Aphids on viburnum Buldenezh eat all the flowers - what to do?

Unfortunately, like most cultivated plants, viburnum is a source of food for black aphids. These insects can occupy the plant to the point where the stems appear completely black. Aphids feed on plant juices and also transmit viral diseases through microcracks in the stem. All this reduces the amount of harvest, leads to weakening, withering of viburnum bushes, and even to their complete drying out and death.

Black aphids attack not only viburnum, but also most fruit trees and shrubs, such as cherries, cherries, and ornamental plants, and can move between them, infecting the entire garden. The affected plant is easy to notice - its leaves are deformed, swollen, curled, and covered with dark spots. Such bushes dry out quickly and do not produce the expected harvest. The dusty, brownish coating of the feces of these parasites contributes to the development of sooty fungus, mold and rot. In general, the aphid population can delay plant growth for 30 days.



Aphids on viburnum: possible insect pests of viburnum trees

The tree that I love the most is the black aphid. She literally lives on it. At the end of summer and beginning of autumn, adult specimens begin laying eggs in the bark and space near the flower buds. This is exactly how future larvae overwinter. With the arrival of spring, the larvae begin to hatch, move onto young foliage and feed on its juices. This causes curling, deformation and the appearance of black spots on the foliage. The older the individual, the more harm it causes. Because over time, aphids move to young branches, which can cause them to dry out. Towards the end of the spring period, individuals with wings begin to appear. These are females and males who can already begin to reproduce. You need to start fighting aphids on viburnum at the moment when the foliage is already beginning to bloom. The pest insect can move to other crops, but it will live specifically on viburnum. During one growing season of a tree, the pest will hatch several generations.

How to spray roses, currants, apple trees with ammonia against aphids

When processing currants, you need to unroll the curled leaves so that the ammonia gets to the pests.

Ammonia is a nitrogen-containing fertilizer. Nitrogen acts on the plant as a growth stimulator. After applying nitrogen, plants increase their green mass. Therefore, it is best to use ammonia against aphids during the period of active growth of garden crops. The ideal time is early spring from April to mid-May. During the period of ripening of fruits and flowering of decorative flowers, it is better to choose another method to combat insect pests.

Roses and other crops should be sprayed several times a season. After spraying, the garden will live without insects for approximately 10 days to three weeks. After the appearance of the first winged individuals, the treatment should be repeated in order to avoid the spread of numerous offspring of insects.

Safety when spraying the garden with ammonia solution

  • sparrows, tits, skrovets, and other small birds will also help destroy aphid settlements. Lure them with feeders, drinkers and birdhouses;
  • plant onions, garlic, herbs - thyme, basil, etc. under the bush. Their smell is unbearable for aphids, so with a high probability the insects will not want to settle nearby. Marigold and pyrethrum are also suitable for this purpose;
  • Some beautiful flowers will not only decorate the garden, but will also attract most of the insects. These are calendula, poppies, cosmos, mallow, etc.

Before the buds appear, the viburnum bush can also be treated with Nitrafen infusion (200 g of product per 1 liter of water). We should also not forget that one of the main reasons for the spread of aphids is ants that feed on the pest’s secretions.
