Apple disease and their treatment
Diseases of garden apple trees can affect both the tree itself and the fruit. In this case, the diseases of the trunk and leaves of the tree are directly distinguished. Here is a list of the most common diseases of apple trees:
- Powdery mildew. This fungal disease affects the leaves, buds and shoots of the tree. The disease appears as a white coating, which eventually begins to acquire a brown tint, and then small black dots appear. At the first manifestations should act immediately. The tree is treated with a drug called "Topaz" (you can use "Skor") in the active growth phase, and after flowering apply "Hom".
- Porsche. The most common disease among fruits and leaves is apple. The onset of the disease occurs in the early spring after the buds are blooming. On the leaves appear greenish-brown spots, and after a while the leaves dry and fall off. From the leaves, the fruits also become infected: as a result, gray spots appear and the fruits stop growing. To prevent this disease of garden apple trees, gardeners are advised to do timely pruning, periodic thinning of the crown for good ventilation.

On the apple appears a brown stain, which eventually grows and infects almost the entire fruit. To fight it is necessary to immediately remove the infected fruits, which then need to be buried further away from the garden. In addition, it is necessary to constantly deal with garden pests, you can apply treatment measures, as in the case of the porcine.
- Among the most dangerous diseases of the apple tree trunk is "black cancer" , which refers to fungal diseases. Can affect leaves, flowers or fruits. But the most dangerous form of the disease is the defeat of the apple bark. This disease manifests itself in the form of depressed violet-brown spots, which eventually grow larger. As a result, the cortex is cracked and irradiated, and the tree eventually dies. Fungal diseases of apple trees appear in weakened plants and their treatment is directed not only at eliminating symptoms, but also taking measures to strengthen the tree bark. Wounds are cleaned and treated with a disinfectant.
