Peaches are often sick and affected by pests, but most gardeners point out one problem - curly. This disease can not only spoil the leaves of the plant, but also at times reduce the yield. Peach Curliness - the causes of the problem, the methods of control will be described in detail below.
Where does peach leaf curl come from?
The cause of the problem is the Taphrina deformans. It strikes a tree through any wound or crack in early spring. The affected leaves spread the spores, the latter fall on the trunk and branches of the tree, overwinter, and the next year a new cycle of the disease begins.
Peach leaf curl
Peach leaf curl is hard to miss. The most susceptible diseases are young leaflets that are not more than 2 weeks old. Adults or old leaves do not usually get sick. In this case, the disease develops very rapidly.
The problem manifests itself in the form of blisters on the leaves. They are initially light green in color, later turn red, and then turn brown. At this time, they appear bloom, where the spores of the fungus are heated. Later, the bubbles become brittle, and the leaf itself is compacted and as a result it falls. On the whole branch, after an illness, no more than 2-5 leaflets can remain - if the problem is solved on time. It is not recommended to run it.
The worst thing in the fungus is that the peach curl affects not only the leaves, but also the shoots. They turn yellow, swell up, dry up. And since the young twigs are sick, then after a tree is damaged by a disease, it is pointless to wait for the harvest for the next year.
Fruits in the first year of the destruction of the tree may also become infected. On them, this is reflected in the deformation, small size, as well as poor taste.
The chance that such a weakened tree will bear the winter is extremely small. Moreover, as early as May, it may not even have any leaflets on it, because since March, disputes will diligently destroy branches, buds and young leaves.

The most dangerous time for a tree is early spring. The fungus is active during periods of high humidity and medium temperatures. Therefore, it is precisely in early spring that you need to start treating the plant with all available means.
