Corado (insecticide): instructions for use, composition and properties

The main properties of the product "Colorado"

The drug for controlling the Colorado potato beetle "Colorado" is a powerful insecto-fungoacaricide with a triple action effect (intestinal, contact, systemic), which has a positive effect on the process of eliminating the population of insect pests.
The active ingredient in the remedy for Colorado beetles and other insect pests is the neonicotinoid imidacloprid, contained in Colorado in the amount of 200 grams per 1 liter of concentrate.

Imidacloprid, acting on the central nervous system of the Colorado potato beetle by binding to the corresponding receptors, causes paralysis of the pest and its convulsions. The death of the Colorado potato beetle population occurs very quickly, and the maximum impact occurs within 3-5 days after spraying the plants with the product. High residual activity allows the substance to maintain a protective effect for up to 14-28 days.

Imidacloprid has a crystalline structure and the following physical characteristics:

• molecular weight value – 255.7;
• melting point value – 136.4-143.8°C;
• solubility in water at a temperature of 20°C is 0.51 grams per 1 liter of water.

Methods of storage and combination with other drugs

If the solution is fresh, then it is not stored, but used immediately.

Storage Features:

• the packaged drug is stored for 3 years;
• average temperature from +5 to +35 degrees;
• store in places out of reach of children and animals.

It is recommended to store and use separately from other drugs.

The product contains components that are inconsistent with other substances.

Other means may include:

• insecticides;
• fungicides;
• biological products;
• poisonous compounds;
• activators and growth regulators.

Note! The exception will be alkaline components. Before use, a small chemical compatibility test should be carried out.

If a sediment remains, the incompatibility is obvious.

The poison can be used against various insects and for a variety of crops. Features of dilution proportions, waiting periods and other standards will be given below.

Examples of plants and processing features:

1. Potatoes – removes the Colorado potato beetle and potato ladybug, the working rate of the solution is 5 ml per 20 liters, normally 4 ml per 100 square meters should be used. Spraying should be carried out during the period of insect reproduction and the activation of crop growth. 1 treatment is enough, work can begin 3 days after spraying.
2. The main pest of apple trees is aphids. For leaves, use 5 ml of solution per 20 liters of water, and for aphids feeding on shoots, 10 ml of solution per 10 liters of water. Application rates are as follows: 2 or 2.5 liters per young plant, 3-3.5 liters per plant of medium height and up to 5 liters per mature tree, with a crown with a diameter of 12 - 15 m. The norm can also be determined by eye - the solution should cover surface with a film, without dripping. Spraying should be carried out after the flower corollas fall off and the ovaries form. The waiting period is 20 days, 1 treatment is enough, and you can start work after 3 days.
3. Carrots for storage - carrot fly. Prepare the solution in the proportion of 1 ml of chemical per 1 liter of water. The norm is 1 liter per 100 square meters. Crops are sprayed twice: during the first mass attack of pests and after 21 days. The waiting period is 30 days. Work begins in 3 days.

Treat all plants, as well as the surface of the potato bed, at the same frequency, with the exception of onions.

Description and release form

This is not just a remedy for the Colorado potato beetle and its larvae, but also a remedy for aphids, onion and carrot flies. The Corado insecticide is produced in India and supplied to our market not so long ago, so it is not known to all farmers.

The insecticide contains special components that are obtained from a fungus of the genus Streptomyces. The active ingredient of this drug is imidacloprid, it has a sharp, specific odor that is not dangerous to the human respiratory tract.

“Corado” is sold in liquid form, packaged as follows:

• 1 ml ampoules, packed in a bag;
• boxes with 1 ml ampoules (5 pcs.);
• glass bottle 10 ml;
• glass bottle 25 ml (box).

Instructions for use are included on each package.

The good thing about the Corado insecticide is that it has a long shelf life, is resistant to moisture and direct sunlight, stays on plants for at least a month after spraying, and the insects themselves have not yet developed immunity to it, so they die immediately.

Purpose

Insecticide "Korado" is a systemic drug with long-term protective action:

• potatoes, eggplant (from the Colorado potato beetle and its larvae);
• apple trees, gooseberries, currants (from aphids, leaf rollers, codling moths , etc.);
• vegetables (from soil-borne onion and carrot flies and their larvae).

Examples of Corado preparations for Colorado potato beetles and aphids

Advantages of the drug

Those who, before using Corado, unsuccessfully fought the Colorado potato beetle with other poisons, note the following advantages:

1. Nice price and low consumption.
2. Easy to use.
3. Suitable for controlling eggs, larvae and adults of Colorado potato and other pests.
4. Can be used on different crops (cherries, cabbage, potatoes, currants, cucumbers and tomatoes, onions, carrots).
5. Economical. It takes 1 ml of the drug to process a potato field of 1 hundred square meters. This is one dose per ampoule.
6. Does not harm animals or humans.
7. High efficiency. The action begins after a single application.
8. Long shelf life.

Corado kills pests, causing paralysis, and becomes part of its structure, as a result of which the plant becomes stronger, grows better and gains immunity for the entire period of action. Vegetables do not suffer from the use of chemicals, but the pest, which managed to hide from direct contact with the drug by eating the pulp of the greens, receives a dose of poison along with it and dies in two or three days.

Historical reference

The liquid in the ampoule or bottle is a solution of a substance called imidacloprid at a concentration of 200 g/l.
This newest chemical was developed by the German chemical and pharmaceutical company Bayer. Its sole worldwide patent recently expired and imidacloprid is now free to be produced and sold by any entity. A large quantity is produced in China and supplied for packaging to other countries. Imidacloprid belongs to the chemical group of neonicotinoids - artificial analogues of the natural alkaloid nicotine.

The alkaloid nicotine is found in the tops of plants of the Solanaceae family. There is especially a lot of it in tobacco. Even in ancient times, it was noticed that tobacco infusion had a detrimental effect on many insects. In the twentieth century, artificial pure nicotine was synthesized, but it turned out to be a strong poison not only for insects, but also for humans. Scientists continued their research and developed new substances - neonicotinoids, which are poisonous to insects in small doses, but relatively safe for humans and animals.

In the modern world, 5 main neonicotinoids are used to control insects in everyday life and agriculture:

• thiacloprid (only for large agricultural enterprises),
• thiamethoxam (Aktara),
• acetamiprid (Stozhar, Mospilan),
• clothianidin (Apache, Bushido, Punisher),
• imidacloprid (several dozen drugs).

Advantages and disadvantages of the drug "Colorado"

"Corado" is an effective drug for controlling the Colorado potato beetle and aphids

From year to year, the fight against the Colorado potato beetle remains one of the main problems of almost all gardeners.
At the same time, the Colorado potato beetle quickly (over several years) acquires resistance to traditional drugs. This year we recommend that you purchase a new, very effective drug, Corado. It guarantees almost 100% death of adult beetles and larvae of all ages, as well as the death of newly hatching larvae. “Corado” protects potatoes for a long time: for 3-4 weeks after spraying. That is, just one treatment is enough for the whole summer! At the same time, the drug does not penetrate into potato tubers and does not accumulate in them.

Systemic drug - protects even young growth growing after spraying.

Works well in all weather conditions. It is not sensitive to summer heat and is not washed off by rain.

Note:

after spraying, within one to an hour and a half, the beetles and larvae stop feeding, but still continue to move and retain signs of life for some time. The complete death of all pests occurs approximately on the second or third day, although the beetles are neutralized already from the first hours after treatment.

"Corado" is a very economical drug. To guarantee victory over the Colorado potato beetle, only 1 ml of the drug per 4 liters of water is enough to spray 1 hundred square meters. The drug is available in 1 and 5 ml ampoules and 10 ml bottles. Everyone can choose the most convenient and profitable packaging for themselves.

It will help defeat not only the Colorado potato beetle, but also aphids. Aphids are one of the most difficult pests to eradicate. Developed resistance to a number of drugs, incredibly fast and massive reproduction have made aphids a real scourge of our gardens. “Corado” guarantees almost complete destruction of aphids and protection against them for at least three to four weeks. With timely and high-quality spraying, one treatment will be enough to protect plantings and crops for the whole season. "Corado" is a unique drug, a real find for gardeners and gardeners.

"Corado" - destroys beetles and aphids. There will be no survivors!

The principle of operation of the product

The active substance amidacloprid in Corado is a nerve poison with a specific property. After penetrating into the sap of the plant, the poison is absorbed, moves through the vessels, distributed throughout all its parts. Under the damaging effect of the active substance, the transmission of impulses from the central nervous system to muscle cells is blocked.

Poisoning causes involuntary muscle contractions, which gradually become convulsive and then completely paralyzed, as a result of which the larvae that eat the plant leaves die.

The drug is distinguished by its duration of action, its protective properties persist for a long time after spraying.

On a note! A distinctive property of pesticides based on imidacloprid is that there is no ability of pests to become accustomed to this poison.

Operating principle

During crop treatment, imidacloprid penetrates into the plant in the shortest possible time. The substance becomes a kind of both an internal defender of culture and an organic stimulator of its growth. When eating a plant, small doses of imidacloprid enter the insect's body, but this is enough to paralyze the nervous system of the pest. The insect begins to lose vitality, stops feeding, and 2-3 days after contact with the chemical it completely dies. The Corado insecticide destroys both adult insects and their larvae and reduces the viability of eggs.

The uniqueness of Corado lies in the fact that the drug has a long period of protection: pests do not get used to the product, even if adult insects or their larvae managed not to die after the first treatment, for 3 seasons. After the 3rd treatment of plants with Corado solution, it must be alternated with an insecticide that contains another active ingredient.

Compound

The active component is a broad-spectrum insecticidal substance - imidacloprid. There are no populations of Colorado potato beetles resistant to this poison. The poison acts in several directions, providing high efficiency in a matter of days.

The insecticidal substance acts by contact-intestinal route. The maximum concentration of poison is maintained for 5 days after processing the potatoes. It penetrates into the body of insects when the product comes into contact with the chitinous cover, during feeding.

Corado from the Colorado potato beetle

Instructions for using the drug against the Colorado potato beetle

It makes more sense to use the product only when there is a real danger to the crop. It carries environmental risks and is not suitable for thoughtless prevention.

Storage conditions

Use within three years from the date of manufacture.

Store in a room where it is no colder than -5 degrees and no higher than +25. Do not allow fire, do not burn.

Objects of influence

The chemical causes paralysis of the nervous system of insects.

The Colorado potato beetle and its larvae die from direct contact with the pesticide (contact effect), as well as from eating foliage (intestinal poisoning). Oviposition is not affected, but hatched larvae also die from poison in the food (greens remain poisonous for almost a month after treatment).

The 28-spotted potato ladybug is a dangerous beetle that destroys potato tops in Primorye and Sakhalin. The fight against it is similar to the measures taken against the Colorado potato beetle.

Aphids on the apple tree are destroyed at any stage of the growing season. It is advisable to capture it during the initial period of resettlement.

The biological insecticide Fitoverm (analogues - Iskra Bio, Akarin) copes well with any aphid; it is safer for the environment.

Spraying the garden with corado

Processing times

• The treatment is carried out once, when pests are first detected on plants.
• Avoid windy weather.
• It should be at least 4 hours before it rains. Then the chemical will penetrate inside the plants, and precipitation will no longer weaken its effect.
• Choose the evening (after 18 o’clock), or at least the morning (before 10 o’clock). This way there is less exposure to the sun and it is safer for the bees.
• Temperature does not play a big role (the optimal range is wide: from +10 to + 26).

Application technology

The pesticide is applied by spraying. The spray should be fine (a broom is not suitable).

1. The ampoule (bottle) contains a liquid concentrate, which is diluted with water - first in a small amount, then brought to the required volume. Prepare the solution before use and do not store it for a long time.
2. Recommended dosage: 1 ml of concentrate per 4 liters of water.
3. There is no need to soak the plantings abundantly. Surface spraying with a consumption of 4 liters of solution per 1 hundred square meters is sufficient. If at least a third of the plant is processed, the tissues will have the required concentration.
4. Corado can be mixed with fungicides (for plant diseases), except for copper-containing preparations.

Impact

In the very first hours, insects almost cease to live. Complete death occurs after 2-3 days, maximum after 5. Protection from emerging larvae and newly arriving individuals lasts at least two weeks, up to a month.

Spraying potatoes against the Colorado potato beetle

Precautionary measures

1. Usually the drug does not irritate the skin, mucous membranes of the eyes and mouth, but it is better to protect yourself with standard protective clothing.
2. All work must be carried out in the absence of children and pets.
3. Do not spray flower plants visited by pollinating insects.
4. Do not allow splashes to come into contact with other plantings, especially green crops. They quickly penetrate inside the plants and cannot be washed off with water. Heat treatment (cooking, frying) will not help either. The pesticide is destroyed only over time: in the plant after a month, in the soil after almost a year.
5. Corado is destructive to aquatic life. Do not spray near water bodies, much less send the remaining solution into them. They are poured into a hole and covered with earth.
6. It is allowed to enter the treated plantation three days after treatment. After 10 days, the concentration of poison in the leaves and tubers decreases. The foliage will be poisonous to insects for another 10-20 days.
7. Imidacloprid has a 3rd (medium) hazard class for humans, mammals, and birds. (Accidental) consumption of concentrate and freshly processed greens should be avoided. Symptoms of poisoning: breathing problems, trembling limbs, lethargy; in this case, urgent medical attention is required, otherwise the liver may be damaged. Long-term dietary exposure to small doses can disrupt the endocrine system.

It is recommended to wait at least three weeks after spraying before digging potatoes.

Corado is very effective in the fight against the Colorado potato beetle. It acts quickly, is not addictive, and reliably protects the plantings for another month. The pesticide is used strictly when necessary, with strict adherence to all safety rules.

Consumption rate for different plants

The insecticide is used for spraying potatoes, tomatoes, eggplants, apple trees and other crops. Consumption rates and dosages for each plant are different, so before using the product you must carefully read the instructions contained on the package.

Potatoes - to destroy the Colorado potato beetle, 1 ml of the drug is used per 100 m² of plantings. If there are wireworms in the soil, before planting, it is recommended to treat the tubers in Corado solution, which is diluted at the rate of 1 ml of insecticide per 10 liters of water. In private farms, 4 liters of working fluid are consumed per 100 m²;

Apple tree - treated during the growing season when a large number of aphids appear. The solution is prepared at the rate of 2.5-5 ml of product per 10 liters of water. One medium-sized tree requires about 5 liters of finished working fluid.

Expert opinion Stanislav Pavlovich A gardener with 17 years of experience and our expert Important: Corado should not be used during flowering of garden and vegetable crops, as this can cause mass death of pollinating insects.

Drug toxicity class and precautions

This product is allowed to be used on private farms. Hazard class of the Corado insecticide for humans – 3, for bees and inhabitants of water bodies – 1

.

Therefore, the product cannot be used during the flowering period of cultivated plants and the mass flight of bees, as well as in the water protection zone of reservoirs.

During processing, care must be taken to ensure that the solution does not fall on neighboring crops. Also, do not spray against the wind.

Important!

To prepare the solution, do not use containers intended for storing food.

Spraying is carried out in the absence of children and animals. From the moment you prepare the working solution until the end of the work, you must wear a suit, rubber gloves and a respirator.

During treatments, it is prohibited to eat, drink and smoke. After finishing work, you need to take a shower and wash your face and hands with soap.

You can go to the site only three days after the treatment.

Preparation and use of working solution

To get a positive result, you must use the insecticide correctly. To treat tomatoes and eggplants growing in open ground, as well as potato beds, the solution is diluted at the rate of 1 ml of product per 5 liters of water. Before preparing the working fluid, it is recommended to warm the water to room temperature.

If there are wireworms and aphids on the site, you will need to dilute 5 ml of Corado in 10 liters of water for potatoes, cucumbers and tomatoes. The same dosage is used when processing vegetable crops that grow in a greenhouse.

It is better to spray plants in the morning or evening, in the absence of strong wind.

Mechanism of action

Chemical formula of imdacloprid

Imidacloprid (chemical formula and its spatial model in the figure on the right) and in Corado remains a neonicotinoid - a neurotoxin (nerve poison) with a specific effect. Imidacloprid causes, so to speak, abnormal discharges in the nicotinic acetylcholine postsynaptic membranes of the synapses of nerve cells, i.e. blocks the transmission of “command” impulses from the central nervous system to muscle cells. As poisoning progresses, involuntary muscle contractions begin, turning into convulsions and complete paralysis, resulting in death. Neonicotinoids have the strongest effect on insects (all without exception); weakest on vertebrates. But the mechanism and consequences of poisoning are the same in all cases, only the lethal dosage is different.

Therefore, precautions when working with neonicotinoids should be strictly observed.

Instructions for use

When diluting the drug, you need to take into account the area being treated. The consumption of "Colorado" is 1 ml per 1 hundred square meters (100 sq.m.). The procedure is carried out in the early morning or evening so that it has time to be well absorbed, which will protect gardeners and their animals from harmful fumes of the drug. The treatment should be carried out in the direction of the wind at a speed of no more than 2 m/s, so that droplets of the solution do not fall on the summer resident.

Dilute the product (1 ml bottle) in 5-10 liters of water at room temperature. Mix well, pour into a spray bottle and irrigate plants infested with insects. They process carefully so as not to miss a single bush. Especially the leaves, where there is a large concentration of larvae. Dilute Colorado immediately before use, while protecting the skin and respiratory tract. The solution must be used immediately.

Important! The treatment procedure should be carried out no later than 20 days before harvest, so that imidacloprid has time to erode. In areas with high harmfulness of the leaf beetle, the use of the drug begins when insects colonize 5% of potato bushes or when their first larvae appear.

How to apply

Each package of Corado product of any volume is supplied with instructions for use, which indicate the type of pest, the crop on which it has settled, liquid consumption (for example, per one tree or one hundred square meters of area), the rate and period for which the treatment is intended, its effect .

The drug is prepared using the instructions in the instructions on how to dilute. To make a liquid solution from the drug concentrate, follow the instructions on the package. Against larvae and adult Colorado potato beetles, take 1 ml of the product and five liters of water at room temperature, stir, bring the volume up to twenty liters again with water and pour the resulting solution into a spray bottle.

Typically, five liters of the mixture is enough for one tree, and the same amount of toxic liquid will be needed to spray a hundred potato and tomato plants. Dilution of the drug is done strictly before treatment or used within one day. There is no point in storing it.

Application area

The popularity of Corado is caused not only and not so much by the relatively low price combined with catchy advertising. Based on the complex of properties of the drug, it is possible to determine the scope of its use in private household plots:

• Corado, like its chemical “brothers,” is primarily a remedy for the Colorado potato beetle on potatoes and aphids on apple trees.
• At the same time, the drug is applicable against some pests that are “atypical” for neonicotinoids, see below.
• Corado is not only a one-time “first aid” for a massive pest invasion: this drug is applicable as a powerful means of ongoing (planned) control of target objects of elimination.
• For potatoes, in exceptional cases, it is permissible to use the drug twice during the season, and for some. For other crops, 2-fold processing is routine (also see below).
• In the black soil zone and south of Corado, it can be used for up to 3 seasons in a row, without fear of the accumulation of the active substance in the soil.
• Corado is not applicable for protected soil crops (in greenhouses).

Note: in addition to apple trees, Corado from pome fruits is applicable according to the same regulations on quince and medlar (loquat, sheseku). But it is unacceptable to use it on pears, stone fruits and berries - the active substance will penetrate through the cuticle of the ovaries into the ripening fruits and remain in their pulp for an indefinitely long time!

“Colorado” and “fly” Corado

Corado drug against onion and carrot flies

LLC “Vashe Khozyaystvo” offers Corado in 2 commercial formulations: against the Colorado potato beetle and against onion and carrot flies, see fig. on right. The visible difference between them is the granularity of packaging: “Colorado” corado is bottled in ampoules of 1 and 5 ml and in bottles of 10 and 25 ml. Ampoules with a capacity of 1 ml are packaged individually or in blisters of 5 pieces; 5 ml ampoules individually. “Fly” Corado is packaged in blisters in pairs of 2 ml ampoules.

The chemical composition and effect of Corado in any packaging are identical; as they say, “they poured from the same barrel.” The difference in packaging size is explained by ease of use against target objects, see below. But if for some reason it is more convenient for you to poison the “Colorados” with the “fly” Corado or vice versa, do not hesitate - the effect will be the same, because the substance in container units is the same.

Note: the expression “they poured from the same barrel” has a relatively recent origin, from a Soviet joke. A Krokodil correspondent interviews the director of an Armenian wine and cognac company. He asks: “At the competition in Paris, your 3-star cognac won a gold medal, but your 5-star cognac did not reach the finals at all. How do you explain this? He throws up his hands - “I don’t understand. They poured from one barrel."

Corado from cows

In addition to the target elimination targets indicated on the packaging, both Corado formations are equally effective against another pest - the 28-spot or potato ladybug. This cute little bug has not yet gained the sad fame of its striped “colleague,” but in some regions it successfully competes with it in terms of harmfulness.

Pest potato beetle (28 spot) ladybird

The color of the potato ladybug is variable (see figure), even the number of spots is not necessarily 28, but this does not make it any more harmless. In addition, 28-spotted, like all ladybugs (including beneficial entomophages) can be dangerous to humans. From time to time, ladybugs are attacked by some kind of beetle rage; they attack people in masses and bite. Ladybird bites are weak (they do not bite through the skin until it bleeds), but are poisonous. There are known cases where hordes of maddened ladybugs have eaten people to death. Single, extremely rare. Therefore, there is no need to exterminate insectivorous ladybugs, especially since the most useful 7-pointed ones rage much less often than others

Corado from the Colorado potato beetle: features of the pesticide, use

With the onset of the summer season, many people have a question about how to deal with pests this year. Among the many drugs, Corado for the Colorado potato beetle is the most effective. This is a fairly new product that can be used to treat not only potato bushes, but also other crops.

Features of the drug against the Colorado potato beetle

Corado belongs to a group of pesticides that fight not only Colorado potato beetles, but also annoying aphids. The product is produced in ampoules of 1 ml or in the form of bottles of 10, 25 ml. The packaging is sealed, which prevents poison from spilling during transportation.

Since the drug belongs to hazard class 3, it must be kept away from children.

Compared to other products, Corado has many advantages. An important advantage is its resistance to moisture and scorching sun.

Other positive aspects of the product:

• Pests do not get used to this drug, since it is one of the new ones;
• fulfills its protective properties throughout the month;
• has a quick effect on pests;
• low price category;
• destroys not only adult beetles, but also their larvae.

The mixture consists of an avermectin complex. It is obtained from mushrooms of the Streptomyces family. The main active ingredient of Corado is imidacloprid.

The product can be stored for 3 years, provided that the packaging has not been opened. It is not recommended to keep the printed ampoule for more than a day. In this case, the temperature regime of the room must be observed. The optimal indicators are -5C - +25C.

Used ampoules must not be burned. They should only be thrown away in designated areas.

Corado from the Colorado potato beetle: the effect of the composition

The components that are included in the composition negatively affect the nervous system of beetles. Within 2–3 hours after spraying the bushes, the pests stop feeding on them. Then the beetles begin to experience paralysis and convulsions. As a result, pests and deposited larvae die. This happens after 48, 72 hours.

You can work with Corado in any weather conditions.

Ways of getting the product into the body of insects:

• intestinal;
• systemic;
• contact.

The drug is also used to treat plants against aphids, ladybugs, and spider mites. Insects do not get used to this product, so it can be used throughout the summer season.

How to use Corado

To get maximum results the first time, prepare the mixture according to the instructions on the package.

The drug acts only on insects and is not able to penetrate the tubers and the stem.

The first thing you need to do is prepare a container. The liquid must be diluted in a bucket that is not used for food purposes. Take water only at room temperature and dilute an ampoule of the drug in it. Mix everything thoroughly and you can start processing.

Plants must be sprayed with a spray bottle. You can also use a broom or brush.

Potato bushes must be processed at least 20 days before harvest. It is recommended to carry out the procedure early in the morning or in the evening, when the sun has set. This way it will be possible to protect the plants from leaf burns.

Corado is not recommended to be mixed with other types of drugs. The mixture is not compatible even with the compounds that are included in its group.

Precautions when working with the drug

To get the desired result and not harm your health, you must follow some rules.

It is recommended to prepare the product only with rubber gloves, a respirator and safety glasses. All other parts of the body will need to be covered with clothing.

In addition, the following rules should be observed:

• do not consume water and food;
• do not use food containers for work;
• If the product gets into your eyes or nose, you should immediately wash them with clean water;
• if it gets into your mouth, you must rinse the cavity thoroughly with water and then drink more than 1 liter of liquid;
• After finishing working with the poison, it is recommended to drink a glass of water with soluble activated carbon.

Before you start treating plants, you should remember that the drug can negatively affect bees and domestic animals. Therefore, if there is an apiary nearby, it must be moved to a safer place.

Corado is a potent remedy for the Colorado potato beetle, which does not cause pests to become addicted to the active ingredient.

But despite all the advantages of the drug, we must remember that it has a number of features that should be taken into account when processing crops.

Is it possible to spray potatoes during flowering?

The instructions state that the Corado insecticide is not recommended for use during the flowering period of plants.

Important. If you didn’t have time to spray for beetles before flowering, but flowering has already begun, you need to use folk remedies.

Bees pollinate plants, and potato flowers also “lure” these beneficial insects. Corado can be toxic to bees. During the flowering period, potatoes have a weak protective ability against pesticides.

Attention! The drug must be diluted in a non-residential area.

How does the drug against pests work: spectrum of activity

Over time, the Colorado potato beetle and a host of other pests can perfectly adapt to the influence of various chemicals and poisons. This is due to the fact that such pests multiply very quickly.

But in the case of Corado, everything is completely different. This drug ensures that there will be fewer harmful insects, and by the end of the season almost all of them will be exterminated. Corado is not afraid of sunlight and does not lose its properties depending on weather conditions.

Just a couple of hours after treating crops with poison, it affects the nervous system of insects, and causes them to stop eating and no longer harm the plants.

A day after using Corado, the larvae of the Colorado potato beetle will begin to die, and after some time, all adult representatives of these insects will completely die.

Work regulations

The procedure for preparing the working solution (s.r.) is to open the ampoule/vial, dissolve the concentrate in a small amount of water, mix thoroughly and add water to the required volume (see table).

Treatment is carried out by spraying with r.r. using a garden sprayer in the morning or evening hours before sunset, in calm weather. When applying the drug to the vegetative parts of the plant, you should ensure that the leaf plate is evenly wetted on both sides. And although the manufacturer claims that the drug is not washed off by rain, it is still recommended to carry out treatment 4-6 hours before rain to ensure maximum impact of the drug.

The Corado instructions define a high rate of impact on insects - within 1 hour after treatment.

Treatment of potatoes and eggplant against the Colorado potato beetle

Treatment of potatoes against the Colorado potato beetle with the insecticide "Corado"

Treatment of potato plantings against the Colorado potato beetle and its larvae is carried out when they appear en masse. The period of protective action against the beetle and its larvae is at least 14 days. The number of treatments is no more than 2.

Treatment of apple trees, currants, gooseberries from aphids, etc.

When fruit and berry bushes or trees are infected by aphids and other pests, repeated treatment up to 3-4 times is allowed, although usually double treatment is sufficient. The waiting period before harvesting should be at least 20 days.

Treatment of vegetable crops against carrot and onion flies

The regulations establish two stages for processing carrots - the first spraying during the first emergence of flies, in the phase of 2-4 leaves, and the second spraying 20 days later.

For onions, two sprays are also carried out. The first treatment is spraying the sets before planting, the second treatment is in the phase of 3-4 onion feathers. It is prohibited to use the drug to treat onions grown for harvest.

Reviews about Corado are mostly positive if the product is used correctly. Allowed to be used in summer cottages and fields.

We have been processing Corado potatoes for three years now. The result is wonderful. Our neighbor poisons pests several times a season, we only do it once, a few weeks before the potatoes bloom. It kills Colorado potato beetles instantly and protects for a long time. We collect a wonderful harvest without much effort.

Anna, Moscow

Corado is one of the best remedies. We have a large potato garden; we don’t really want to process it several times a season. This poison always helps. We sprayed the plant once and forgot about beetles and other pests. It is economically used, affordable, there have never been any side effects. It’s easy to use – dilute the insecticide in water and pour it into a spray bottle.

Anton, Voronezh

You can buy an effective remedy for the Colorado potato beetle in a specialized store, at the market, in the hardware departments of supermarkets, or order on websites via the Internet. The price of Corado pleasantly surprises everyone. You can buy a bottle with a capacity of 10 ml for 55 rubles. Should be stored in a dark place, away from sunlight. Must be used within 3 years from date of manufacture.

Corado: reviews of use

Anya, 44 years old, Belgorod region I plant potatoes and tomatoes in my garden every year, and every year throughout the entire season I fight the Colorado potato beetle almost unsuccessfully. And last year I tried the Corado insecticide. The product comes with clear instructions, with which I diluted the working solution and carried out the treatment. The beetle larvae all fell off at once. In 20 days I will carry out another preventive treatment.

Oleg, 50 years old, Rostov region I purchased this drug from my own hands and treated rose bushes against aphids and midges. However, the result was practically zero. I looked on the Internet and it turned out that the drug I purchased was counterfeit. I had to go to a specialized store to get the product. And there I bought a real Corado insecticide, which in one spray dealt with all the pests on the bushes of the queen of flowers.

Natalya, 40 years old, Moscow region Treated onion plantings with this drug against onion flies. First, I sprayed the seedlings with Corado solution before planting, and when the plants had three leaves, I sprayed them as well. As a result, there were no onion flies in my garden this season. One thing you need to know: onions are not treated with such a chemical, as it accumulates in the greens and can cause poisoning in humans.

Many gardeners and vegetable growers note the high effectiveness of the Corado insecticide in the fight against the Colorado potato beetle, aphids, carrot and onion flies

. It is important that harmful insects do not develop resistance against this drug, so it can be used to treat the area for three seasons in a row.

Degree of toxicity

Corado has a hazard class 3 for humans and a hazard class 1 for bees.

Under no circumstances should plants be treated while they are flowering - this can lead to mass death of pollinating insects. It is prohibited to use the drug closer than 6 km from apiaries and 1.5 km from reservoirs in which fish are found.

If after or during spraying you experience nausea, weakness, vomiting, or increased heart rate, you should immediately stop working, take activated charcoal and call a doctor.

Restrictions and security

The instructions for use of Corado indicate a 3rd class of hazard for humans, therefore well-known safety measures should be applied:

• When carrying out treatments, isolate children and pets;
• work in special clothes;
• do not eat, drink, or smoke while working;
• Do not store together with food and medicines;
• when preparing r.r. do not use food containers;
• In case of poisoning, use activated carbon and consult a doctor or consult a poison control center.

The time to enter the areas after treatment is 3 days.

"Corado" poses a particular danger to bees - it belongs to the 1st hazard class. It is strictly forbidden to use insecticide during flowering, or to carry out treatment in the evening after sunset. The summer limit for bees is 4–6 days.

“The insecticide is dangerous for fish and aquatic organisms. Do not allow the drug to get into bodies of water or water sources. Instructions for use “Corado” establishes a sanitary zone to the water source - at least 50 meters.

Precautionary measures

For treatment, you will need thick clothing that reliably covers all areas of the skin, as well as a gauze mask. Before next use, clothes will need to be machine washed using powder. If some of the solution has been spilled on your trousers or jacket, the clothes must be removed as quickly as possible, without dismissing the fact that “it will dry anyway.” Prolonged contact of the insecticide with the skin is hazardous to health.

Contact of the drug with the eyes or mouth may cause poisoning. Under no circumstances should you process against the wind. It is better to hold the spray bottle at arm's length from your face. If Corado does end up in the oral cavity, you should immediately stop processing and rinse your mouth several times. Then you will need to drink 3-4 glasses of warm water and induce a vomiting reaction. After completing the procedure, drink activated charcoal and rest. If it gets on your eyes, you should rinse them for 10-15 minutes, trying to make yourself cry.

When making a solution or processing, the presence of children, animals, and pregnant women is unacceptable. If pets walk uncontrollably around a dacha or country house where insects have been exterminated, it is better to limit pets’ access to the garden for several days. It is also worth making sure that they do not eat poisoned insects. Despite the fact that the dose of poison contained in the body of beetles is extremely small, the animal can suffer if it eats them for pleasure.

If your dog or cat likes to pick through the trash can, wrap the used bottles in a transparent bag. If a child or pet comes into direct contact with the drug, you should immediately consult a doctor.

Description of the drug

Colorado stands out sharply against the background of a variety of drugs with similar effects. It contains the neonicotinoid poison imidacloprid, which can completely destroy the pest beetle.

The additional component is a complex of substances obtained from a special type of mushroom that has a neurotoxic effect.

Fact. Colorado not only kills the beetle, but also spider mites, potato borers and many other insect pests.

Advantages and disadvantages

An undoubted advantage is that pests do not become accustomed to the components of the product. This means that Colorado will always be effective in controlling insects on potatoes. But you shouldn’t use it more than 3 times per season. The effect of the poisonous solution begins immediately upon contact of the solution with pests.

In a matter of hours, both adults and their larvae are destroyed. The beetles die in convulsions after the drug enters their body, and the poison attacks the larvae through the skin, paralyzes them and they die due to the inability to receive food. For about a month after treatment, you can forget about beetles and larvae.

Important. Many gardeners get scared when they see a huge number of pests on their potato plantings on the second or third day after spraying.

This is rare, but is considered normal.

According to the instructions, the effect of the drug lasts from 2 hours to 5 days. Under no circumstances should you duplicate processing.

The advantages include the affordable price. Colorado is sold packaged in ampoules in granular form or as a solution. 1 ml costs approximately 8 rubles. Considering that it is enough to process 10 acres, it turns out to be very affordable financially.

But there are also disadvantages. The most important thing is the high toxicity of Colorado. It belongs to the 3rd level of danger for humans, so it must be used exclusively in protective clothing and under no circumstances should it be inhaled. During work, poultry and animals must be kept away, and if there are hives with bees nearby, then treatment is prohibited. This can lead to the complete death of the apiary. The drug has no other disadvantages.

How it works

The effectiveness of Colorado is due to its triple action:

• contact;
• systemic;
• intestinal.

That is, it destroys pests by getting inside their body, upon contact with the skin, as well as when used systemically, accumulating and protecting plantings from further damage.

Once on plants, Colorado Systemic Insecticide spreads very quickly. When it enters the insect's body, it blocks the nervous system. The beetles stop moving and die.

Colorado has a slightly oily structure, which helps it stay on the bushes longer, not be washed off in the rain and not evaporate in the sun. Therefore, after treatment there is no need to worry about weather conditions. The effectiveness of the drug can only be reduced by a torrential downpour that began an hour after spraying.

Analogues of the drug

Corado has many analogues that contain imidacloprid; they are also effective when used against garden pests. Golden Spark with imidacloprid in its composition is considered a good remedy for combating the Colorado potato beetle. It enters through the contact-intestinal route, affects the nervous system of pests, causes convulsions, then leads to paralysis and death of larvae and beetles.

The result from the toxic substance of the poison is observed already 2-3 days after treatment. It is characterized by high functionality both in the heat and after rain. Imidor. After treatment, the active substance of the drug reaches pests through the leaves, paralyzes the nervous system, and as a result, the beetle larvae stop eating crop plants and die. It is used not only against the Colorado potato beetle, but also against whiteflies and thrips.

Commander. Another analogue of Corado with the active ingredient imidacloprid. Strong organic poison with a concentration of 200 g per 1 liter. Characterized by efficiency at different temperature conditions. It acts quickly on insects after treating plants, penetrating through their leaves, stems, and into the root system. Tanrek. In addition to Colorado potato beetles, it is used against ground beetles, locusts, aphids, leafhoppers, and whiteflies. UV resistant and not washed off by dew or rain.

Attention. These pesticides are interchangeable, but Corado has a wider spectrum of action.

Corado's analogs

There are many drugs with imidacloprid as an active ingredient.

The most popular analogues of Corado:

Biotlin, VRK, Zhukoboy, VKR, Zubr, VRK, Imidor, VRK, Iskra Zolotaya, VRK, Commander, VRK, Konfidelin, VRK, Prestige, KS C, Tabu, VSK, Tanrek, VRK.

Application procedure

Corado working solution for open ground plants is prepared on the basis of a mother solution so that the chemically active solvent does not get on the plants. A measured dose of the drug is poured into 1 liter of lukewarm water (25-28 degrees) and the solution is allowed to stand for 1-5 minutes. In the meantime, fill the sprayer tank halfway, pour the mother solution into it while stirring, and immediately start working, because the working solution must be produced in no more than 4 hours.

Plants are treated according to the usual rules with one exception: the weather must be dry. Working hours are late morning (after the dew has dried) or evening from the subsidence of the day's heat until sunset. The permissible wind force is no more than 5 m/s (thin tree branches sway from time to time). Time before rain – 6 hours.

Corado's working solution for treating seed (see below), due to the low total consumption, is prepared directly in the tank of a hand-held sprayer. Before starting work, the device is kept for approx. 5 minutes with the head removed (with the neck open). The readiness of the solution for use is determined by the absence of the smell of the solvent. You need to sniff chemically: holding the container 15-20 cm from your face, wave your palm over your neck towards you while inhaling. Poking your nose into the neck and sniffing is unacceptable!

Instructions for using the Corado insecticide on private farms are given in table. below. The fungicidal activity of the drug is manifested at a dosage equal to or higher than that indicated in the column for treating onion sets, but at a concentration an order of magnitude lower, the phytotoxicity of the drug is already strongly manifested, therefore exceeding the indicated dosages for treating vegetative plants is unacceptable.

Instructions for use

The instructions for using Corado against the Colorado potato beetle are extremely simple, but require strict adherence to the rules.

1. When working with poison, you need to wear personal protective equipment - rubber gloves, a respirator, a long-sleeved jacket, trousers. Failure to comply with these instructions may result in side effects. In case of contact with the skin, the product causes irritation, an allergic reaction, penetration into the respiratory tract and esophagus. Risks poisoning of varying severity.
2. It is necessary to spray the plant early in the morning or in the evening. Otherwise, the leaves of the plant may suffer from bright sunlight and get burned.
3. The weather should be dry and windless. The spray bottle should be held in such a way that the spray flies in the opposite direction from the person. Particular attention is paid to the back side of the leaves, since this is where the eggs and first instar larvae are located.
4. It is recommended to spray the plant with poison during the growing season once per season. In special cases, repeated treatment is allowed no earlier than 45 days after the previous one. It is prohibited to poison Colorado potato beetles 20 days before harvest.

Efficiency is reduced if heavy torrential rain occurs within 2 hours after spraying. The product should not be used during the flowering period of the crop, since imidacloprid is a lethal poison for bees.

The results of Corado's action can be seen within half an hour. Adults die within 24 hours. The drug kills not only Colorado potato beetles, but also many other pests - potato moths, caterpillars, aphids.

Reviews from gardeners about the drug

Gardeners note the high effectiveness of the drug Corado.

Irina. From year to year, like many farmers, I have one problem: how to get rid of the Colorado potato beetle on potatoes. I tried a lot of different folk remedies and popular drugs, but it didn’t help. There were fewer pests, but they did not disappear completely. I accidentally saw an advertisement for Corado and decided that since nothing was helping, it couldn’t get any worse. Corado insecticide helped me a lot. Colorado potato beetles disappeared from the garden instantly, after one treatment. Now I will always use it.

Andrey. I purchased a summer cottage quite recently, planted potatoes for the first time - and it began. There was no escape from the Colorado potato beetle. I am against insecticides and any “chemistry” in general, but there is nothing to be done. Friends advised me to buy Corado. Excellent tool! Not only did the pests completely disappear from the beds, but the harvest turned out to be enviable. I recommend.

Reviews

Oksana, Vologda A friend told me about Corado when I was visiting her in Krasnoyarsk. To be honest, I was simply tormented by Colorado potato beetles in my summer cottage. I tried everything: poisoned it with tobacco, and collected it by hand. I’m ashamed to say, but I even went to our witch, Baba Zina. She gave out a slander, which, of course, did not help. But Corado coped with his task with a bang! Finally, I can calmly plant potatoes, knowing that no one will spoil them.

Oleg Petrovich, Kazminskoye Korado village I have been using it for three years, and now I’m just looking for a replacement product. During the entire period of use of this drug, I did not notice any beetles, although previously they caused a lot of concern. Before that, I used other means, the names of which, of course, I don’t remember anymore (that was 5 years ago), but they did not have such an effect, but Corado helped out well.

Natasha, St. Petersburg Recently, my friends and I finally moved to an eco-village near St. Petersburg, where we grow all the necessary vegetables and fruits ourselves. We treat potatoes with Corado, which my grandmother recommended to me. Honestly, I can’t say how effective it is, since we are using it for the first time, but a woman from a nearby store, having learned that we didn’t have beetles, asked the name and even wrote it down. She said that she is using another remedy, with zero results so far.

What is the difference?

The full composition of pesticides for spraying treatment includes, in addition to the active ingredients, adhesives (surfactants, surfactants), ballast additives, which to some extent regulate the translaminar and biological activity of the drug (its ability to penetrate plant tissues and effectiveness on objects to be eliminated), and a solvent . The solvent also plays a certain role in the properties and activity of the drug.

While manufacturers willingly disclose the composition and concentration of additives to everyone, branded surfactants, ballast and solvent are a taboo and a sealed secret, known only to the leading specialists of the developer company, especially since there is practically no information on the dangers and toxicological properties of the finished drug surfactant and ballast. influence. But they largely determine the scope of application of the product and the features of its use. Corado's solvent is certainly different from that of other pesticides with neonicotinoids: a pungent odor of some organic volatile liquid spreads from the opened package of the drug.

In terms of general indicators, Corado is the same as its analogues (not complete) at 20% imidacloprid:

• It has high translaminar activity - it is completely absorbed into the plant tissue in 2-3 hours;
• The protective effect is high - correct application (see below) ensures 100% destruction of a pest population of any volume and density at any phase of its development;
• The drug is not phytotoxic;
• Effective against pests resistant to pesticides based on other chemicals;
• Resistance of elimination objects to imidacloprid itself has not been recorded;
• The effectiveness of the drug is practically independent of the weather (imidacloprid is neither photolytic nor hydrolytic);
• Temperature range of effectiveness of the drug is +(12-25) degrees Celsius;
• The degree of danger of imidacloprid for humans and warm-blooded animals is 3 (moderately dangerous substance), but chronic poisoning with microdoses of DV produces long-term negative after-effects, incl. mutagenic and teratogenic (on fetal development in pregnant women);
• In the external environment, imidacloprid persists for a long time (half-life in soil up to 8 months);
• The degree of danger of the drug for bees and aquatic organisms is 1st (extremely dangerous substance).

Note: the craze for such seemingly convenient neonicotinoids has led in a number of countries around the world (the list of which is ever expanding) to the extinction of domestic bees and beneficial wild insects - pollinators and entomophages. This threatens an environmental disaster on a planetary scale. Currently in the EU and some. In other countries, the use of pesticides with neonicotinoids on open ground crops is prohibited.

At the same time, the effect of the drug Corado is noticeably different from agrochemicals for a similar purpose:

1. The speed of action is below average - the pests stop feeding within 2-3 hours and die within 2-3 days (apparently, the manufacturer has developed a surfactant that regulates the translaminar activity of the drug);
2. For the same alleged reason, the protective effect of Corado is longer, up to 20 days;
3. As a consequence of paragraphs. 1 and 2, the effect of the drug on the imago (adult individuals) of the Colorado potato beetle is weakened - the beetles have time to migrate before dying;
4. Some ovicidal activity of the drug was noted: a decrease in the volume of oviposition of pests, anomalies in the development of eggs and a decrease in the percentage of larvae hatching from them;
5. The dosage and consumption rates of the drug are even less than those of others at 20% imidacloprid. This reduces the cost of one treatment, but in no case gives a reason to neglect precautions, see below;
6. Corado in tank mixtures is incompatible with other agrochemicals. However, in private household plots treatment with mixtures is almost never carried out;
7. In certain dosages (see below), Corado exhibits fungicidal activity.

Note: the acaricidal activity of neonicotinoids is a myth, most likely generated by “network hamsters” and “sofa barmalogs”. Harmful mites have a significantly different metabolism than insects. After the use of neonicotinoids, a decrease in the number of predatory mites, pest exterminators, was noted on plants. But in laboratory conditions, the LD50 doses for them turn out to be several times and orders of magnitude higher than for insects. But in natural conditions - well, where do the predators have to go, since, excuse me, all the food has died?

How to prepare the solution correctly

To prepare a working solution of Corado, you must first carefully study the instructions - the insert, the dosage of the drug, and only then proceed with implementation.

1. The ideal container for diluting with Corado is a clean bucket with volume marks up to 5 liters.
2. Pour about 1.5 liters of water into a bucket.
3. Pour 1 ml of liquid drug into it, breaking the ampoule.
4. Shake the liquid carefully.
5. Bring the volume of water to 5 liters.
6. Mix gently again.

This amount of solution can be used to treat an area of ​​1 sq.m. with potatoes. If it seems to you that there are a lot of larvae and beetles, you need to make a more concentrated solution using 3-5 ml of product per 10 liters of water.

On a note! For dilution, you need to use warm water so that the concentrate is completely dissolved.

Product effectiveness

The active substance of the product (imidacloprid) has a detrimental effect on parasites and pests, providing a nerve paralytic effect. After just 1-1.5 minutes they stop gnawing on the plant, and you can notice a slowdown in the motor activity of the beetle larvae. 2-3 days after treatment, the potatoes will not be attacked by Colorado potato beetles.

Corado destroys pests completely, from laid eggs, larvae, to adult parasites. And as advertised on the packaging, there will be no surviving beetles.
