A tree that pleases delicious apples can be found in almost every garden. And let the shelves of shops and markets are full of round fruits, gardeners prefer to feast on their own harvest. It is a pity only that, unfortunately, on the way to the crop are various diseases and pests. So, for example, summer residents complain that red leaves appear on the leaves of the apple tree. It is important to understand what this is connected with and how to deal with this phenomenon.
Red spots on the leaves of apple
The appearance of red spots on the leaves of apple trees is associated with red-throaty aphids. This is called a small green-brown insect, which settles on the underside of the leaves and feeds on them. To recognize the appearance of a pest is simple - usually damaged leaves immediately curl inward along the edges. After that, red convex spots are visible on the apple-tree leaves - wrinkled and dense rolls of oblong-oval form - galls. In case of severe damage, the tree is covered with leaves completely transformed into reddish-crimson platens, where larvae of red-headed aphids develop. If you do not fight with a pest, aphids will become damaged and fruits, as well as pass to neighboring cultures - currants, hawthorn.
The appearance of red spots on the leaves of apple trees is associated with diseases. Reddish spots with orange tint with convex outgrowths on the inner leaf plate are considered a sign of rust development. The disease itself does not lead to the death of trees, but it can weaken it, which is fraught with a decrease in resistance to disease.
