How to get rid of aphids on trees

With the advent of spring, all gardeners begin the “battle for the harvest”, because many bushes and fruit trees attack various pests, among which the smallest and nastiest are aphid, settling on leaves and young shoots. Experienced gardeners know how to deal with aphids on fruit trees, what are the ways to destroy pests, and which one is the best remedy.

What is dangerous aphids for trees

Aphids attacking a tree are hard to miss: as soon as the leaves begin to turn yellow and curl, you can lift them up and see an accumulation of small green, brown-brown or black insects on the back side. Aphid also appears on a tree trunk, on fresh shoots, buds to eat plant juice. Aphids can settle on a birch, poplar and other trees in the forest.

If you do not immediately begin to fight insects with various means, then the consequences for fruit trees can be deplorable (see photo aphids on trees):

  • settling on fresh shoots, the aphid eats their tops, preventing the tree from growing correctly, which then will affect its fruiting;
  • attacking young plants, the aphid is able to completely suck out the juices from them and even completely destroy;
  • small pests are carriers of viral infections, resulting in gall formations on fruit trees, which can cause their death;
  • if you do not destroy the aphid immediately, then the insects will spread to the entire garden, including flowers, berry and ornamental shrubs and other trees.

In the second phase of development, these small insects acquire wings, with the help of which they can fly over long distances, moving between trees and garden plots - this is where aphids from trees come from. Also, ants often carry it on themselves for the purpose of resettlement and reproduction.

On trees and bushes, where there is aphids, most often settle and black ants. They are very fond of the sweet pad secreted by insects, and therefore even breed and guard their settlements. To destroy such a symbiosis, it is necessary to simultaneously fight with ants in the garden.

Aphid control methods

Fighting aphids on fruit trees should be carried out in various ways and means, which must be alternated throughout the season. There are several basic methods:

  • Biological - planting plants (nettles, spicy herbs with a pungent odor) around trees that attract insects that feed on aphids: ladybugs, lacewings, female flies, wasps. Some species of birds like to feast on insects: sparrows, linnet, tits and chicks, for which feeders, drinking bowls and birdhouses are installed in the garden. So that there are fewer pests on trees and shrubs, plants are planted nearby whose smell they cannot tolerate: onions and garlic, chamomile, marigolds, mint, fennel, coriander.
  • Folk methods of controlling small insects include the use of various substances and fluids, which need to be treated with trees from aphids to destroy it.
  • Chemical aphid control agents containing pesticides are highly effective and harmful to insects, it is better to use them in the spring so as not to harm the ovaries and fruits.
