Diseases of apple trees

Apple trees are nourished from the roots and leaves. Therefore, the disease of any of the parts of the tree, if not treated, will lead to death. Why an apple tree dries and what can be done can be determined on the spot. There are various diseases that are transmitted:

  • spores;
  • bacteria;
  • viruses.

Scab

In the spring after blooming of young leaves, oily specks on the young foliage will be noticeable. This is a scab on an apple tree. Over time, the spots on top are covered with velvet bloom, then the whole plate becomes brown. That is why the apple trees not only turn black and the leaves dry at the height of summer, but the fruits are also affected by the disease and become unfit for food.

Scab is a fungal disease. Its spores overwinter on last year's foliage and are introduced into the plant along the green cone, from the moment young leaves appear. The condition for the introduction becomes a slow leaflet, and warm rainy weather. In such conditions, the embedded spores germinate and create a mycelium. Scab often affects old trees with a thick, poorly blown crown. Having developed, the disease first destroys the leaves, they turn black and fall off. Fruits are ugly or fall off after setting.

On the spots there are black dots, under them are spore sacs that open and shoot spores. The bottom of the sheet also gets a yellow spot in this place. In the future, the disease progresses, as seen in the photo. Diseases of apple leaves and their treatment is a process that requires patience.

In addition to leaves, rust in a state of neglect affects the fruits and branches of the tree. Initially, the fungus develops on a juniper, and later, after wintering on plant residues, it falls on a leaf of a tree.

  • on the basis of copper - cuproxate, chlorine oxide, vitriol of copper 1%;
  • Zineb Solution 0.4%;
  • Topaz, Vectra.
