There are a number of proven effective preventive measures against aphids on apple trees, which will help minimize the likelihood of mass reproduction in the garden of this pest.

Why does aphid appear on apples, and how to find it

An apple-tree is struck by a red-headed or gray aphid about 2-3 mm long, with a red head and a black back and tail. Eggs overwinter on the bark of an apple tree, and in spring females are born from them, which contribute to the reproduction of entire colonies on a tree. Insect females are highly fertile and can produce 40 larvae at a time. Active aphids multiply in September. Aphid attacks only those plants that have a high content of amino acids in the juice of the leaves. This may be due to a lack of potassium, phosphorus or an excess of nitrogen. Identifying aphid on an apple is easy: the affected leaves begin to curl down, turn black and dry. Then red blisters appear on the leaves, which signify further twisting and dying of the leaf.

Due to the defeat of aphids leaves are covered with sticky liquid. This is the fall on which the ants crawl. The appearance of ants is also one of the symptoms of aphids in apple trees. In the early stages, it is difficult to identify a pest on a tree, as the aphid begins to settle on top of it. Over time, when insects eat out all the fresh leaves of the apex, they descend to the lower branches, where they are easy to find, it is enough just to turn over any leaf. Since, in addition to eating the leaves, this insect is a dangerous carrier of viral diseases, it is necessary to destroy the aphids on the apple tree immediately after detection.

Unfortunately, even on the most well-groomed and properly processed site there is a high probability of hitting the apple tree by aphids. Since these pests migrate through the air, they can easily fly in from neighboring areas.

How to protect seedlings and mature trees from aphids

Today, the chemical industry is actively developing and to combat pests, including aphids, can offer a wide range of pesticides. At the same time, experienced gardeners use folk pest control methods that have proven to be effective. In addition, biological methods of insect control are widely used as prevention. Next, we take a closer look at how to protect the apple crop from aphids.

However, considering the effectiveness of one or another method of combating insect pests, one cannot call one method a panacea for all cases, since the effectiveness of measures depends on the conditions on the site, the number of trees and associated plants.Sometimes it is even necessary to apply all measures in the complex, because the aphid is a living organism, and it can develop addiction to one or another means.

• planting beside apple trees of special plants that aphids do not like. The aroma of lavender, Dalmatian chamomile, calendula, tomato, garlic or tansy scares off various pests of fruit trees, including aphids.There are also plants that are extremely attractive for aphids, which in no case can not be planted near the apple tree. These are such as nasturtium, hypnotic poppy, kosmeya, mallow, tuberous begonia, viburnum and linden;

This also leads to aphids. Before leaving the apple orchard for the winter, it is necessary to destroy the aphid larvae that have settled for this period in the bark of the apple tree. To do this, in the autumn they are cleaning the bark of trees. Carefully, without damaging the healthy bark of the tree, scrape the dead bark on the trunk and skeletal branches with a scraper or wire brush. First you need to lay a film so that the pieces of bark infected with aphids do not fall around the tree. Then collect everything and burn, along with the root shoots and wen, which are also cut off.
