Brown Spotting - Phyllosis is manifested by round spots with necrotic attacks. Black spots are visible on both sides of the stain - conidia.

Cherry Fruit Rot
Description Cherry disease control and photo fruit with them would be incomplete without the storm of cherry and cherry - moniliosis. A sign of the disease - withered eyelids, and decaying fruit. The development of the disease is rapid, so even the early ripening berry has time to spoil. The task of the breeders was to give the sweet cherry resistance against sweet cherry moniliosis. The fight against the disease lies in the collection and destruction of the cadaver, plant residues on the ground. For preventive treatment using copper-containing drugs. The whitewashing of the boles in the late autumn saves the tree from the gray rot.
On the fruit rot of berries, growths are arranged in concentric circles, as in the photo, the difference between cherry disease and their treatment. At the same time the leaves remain healthy. The berries are removed, the branches with the penetrating disease cut. Sufficient nutrition with mineral fertilizers and spring wood processing with fungicides - fruit rot prevention. On examination, it is possible to determine why the cherry tree rots on the tree according to the location of the pycnidia. The chaotic location of growths is characteristic of moniliosis. In this case, the disease affects the whole tree. Leaves dry out, fruit twigs become fragile, dry, and skeletal branches gradually dry out. If the berry rots in clusters on a tree - it is a sweet cherry moniliosis.

The leaves dry, fall off, the tree does not receive photosynthesis, biological processes slow down. Cherry in the winter goes weak and freezes. Prevention of scab - treatment of black cherry with iron sulfate in the spring, before flowering. Later, the disease is restrained by the drug Chorus.
Why is sweet cherry showered in the middle of summer? The tree fell ill with white rust - a fungal disease. Fallen leaves are removed, and the tree is especially carefully prepared for winter - all the conditions to freeze out.

The photo shows a mosaic disease of cherry, and their treatment is impossible. Signs of illness are found on the leaf plate in the form of strips with a changed color, ring circles. The plate is deformed, changes color, dies. Photosynthesis is impaired, the tree weakens. But the disease moves inward, destroys the sap flow channels.

The Natek on an amber resin trunk should not please the gardener. This is not an infection, but the tree seeks to overgrow a non-healing wound; it sends new portions of gum into an open wound. But the trophic ulcer does not heal, the wood rots, and the gum flows. The reason may not be closed frostbite, breaking branches or improper pruning. Gum can flow if the tree is sitting on acidic soil or groundwater has risen.
After pruning, open the wound should be allowed to dry, and only then dry up with a garden shear.
In order to stop the extraction of the resin, the place must be cleaned, the cut must be treated with copper sulfate, and treated with sorrel leaves for three times with 10-minute breaks. After the cut, close the garden bar.
