town! Put the apple diagnosis! Diseases of apple Black cancer can appear on all aerial parts of plants, but usually on the bark of the skeletal branches and trunks. The illness starts in the field of solar or sun-burns, freezing, frost cracks or mechanical damage. Initially, the cortex appears as a crater, then this dull plot. Then gradually darkens to purple, and then to black. The surface of the cortex becomes like a charred, slightly bumpy or rough. Separate areas crack or crumble., Exposing the wood. For several years the disease extends to the skeletal branches. In this case, the bark swells, behind the wood and cracking. Tsitosporoz or infectious shrinkage occurs in almost all fruit crops. There is defeat trunk, skeletal and thin branches. The bark dries and becomes more reddish, or does not change color. On the surface it appears many easily visible tubercles black. The bark is similar to > and when trying to separate from wood it fray, the branches quickly dry. Common European cancer appears on the branches and trunks in the form of deep cracks with a characteristic wrinkled swimming along the edges. Wounds often reach the core of the tree. In the field of the influx of the branches wither and break off. There are two forms of the disease, closed and open. In the closed form nodules almost completely closed zone, leaving only a narrow slit filled with rotting mass. When open there is the appearance of deep wounds did not grow with the formation of cancer sag at the edges. On apple found both forms of the disease on pear more open. In the spring around the infected wounds appear clearly visible red bumps - spores of the fungus. Remember: all these diseases first appear on the weakened plants. Therefore, the struggle must include not only therapeutic but also preventive measures. In the autumn after the leaves falling and the spring before bud burst, to purge the trunks and branches of skeletal dead bark, cut withering branches, to conduct thorough cleaning and treatment of wounds. If there are signs of black cancer, on the bark garden knives, cut the affected area, capturing 1-2 cm of healthy bark. When cut it a greenish color. Then the wound dezenfitsiruyut1-3% solution of copper sulfate and obscure the garden pitch. Large daubed wounds to wrap burlap. These wastes need to collect and burn! Autumn to protect the trunks and branches of the skeleton of solar-frost Ozhegov spend their whitewash. Collect the fruits of summer are always affected black cancer (as in the crown and the fallen): they were mummified and covered with small tubercles. Should conduct regular subcortex hearth trees - it promotes good development and increase resistance to various diseases
