Spraying is carried out before the flowering of the tree. Well-proven drugs "Lepidotsid" and "Bitoksibatsillin." But they work effectively only if the temperature does not drop below 15 ° C.
- Green caterpillars on an apple tree in a web, paired with very roughly gnawed leaves, will indicate the appearance of a winter moth. The green body is covered with one dark and three light strips on the sides. The danger lies in the fact that the caterpillar crawls inside the kidneys before it dissolves and completely eats up the contents. And later the wrecker switches to leaves and flowers of the tree. In order to fight these caterpillars on the apple tree in the web, in autumn we put on the tree trunks the hunting belts. After bud budding, we treat the trees with pesticides or herbal tinctures. During the period of blossoming, trees can be treated with biological preparations designed specifically to fight this pest.
