Monilia -sthe Disease progresses, particularly in humid and warm weather. A fungus that affects stone fruit during flowering. Flowers turn brown and die. Then dry the young leaves continuing to hang on the branches. Separate branches and the leaves look like a scalded cat. In the summer the mycelium passes the fruit to rot, the part falls off or dries up, staying to hang on the branches until the following spring. The mycelium lives in the tissues of branches and fruits, and "overwinter".
Control measures. Pruning and burning of diseased leaves, fruits and branches. Spraying before Bud break, before flowering, after flowering and in late autumn fungicides ( Bordeaux mixture, copper sulphate, "Hom", etc.)
The shot-hole disease, a fungal disease of stone fruit crops. At the end of June on the leaves spots appear, which later fall out and the leaf becomes dircetory. In severe cases fungus the leaves drop, the fruits are ugly and tasteless, shriveled to the bone. The bark on the tree cracks and starts to leak a sticky amber-colored gum. After wintering kamedetechenie progresses. The fruit affected by fungus, are mummified and remain hanging on the branches.
Prevention. Timely pruning damaged branches, fallen leaves and fruit should be burned. Wound kamedetechenie should be cleaned, lubricated garden pitch. A good tool - the treatment of wounds sorrel leaves are crushed and applied to the affected gum wounds, tied with a cloth.
This disease is often found in gardens, where stone fruit grow in a cold and damp lands, where dense planting.
The kokkomikoza - the malicious fungal disease. Sick of cherry, black cherry, plum in the European part of Russia. The fungus affects mainly the leaves, less often the shoots and fruits, which covered with brown sores with a whitish spore bloom . With severe cases the leaves turn yellow and fall off. Plants become weak and are unable to prepare well for winter, even nearbuy freeze slightly in winter. The disease is favoured by rainy weather, fog, dew, in warm weather, above-20oC. In August, affected by fungus, the leaves massively fall.
Control measures. In early spring the trees treated three times: before opening the buds, before bloom and after it. Use fungicides, for example, "Hom", Bordeaux blend,"Horus". The good result gives application of 5% urea solution in the first treatment. The same treatment can be done in late autumn.
Immune varieties by these fungal diseases have no.
Grade relatively resistant to kokkomikoza: the Muse, the memory of Vavilov, Novella, Kharitonov, Age, etc.
Grade relatively resistant to brown rot: Vole, Melitopol early, Large-fruited Gorshkov, Institute, Orel early etc.
Advice 2 : Why dry cherry
Monilia is a fungus that affects mainly the trees in years with rainy summers and warm winters. Oblubene trees of this fungus - stone rocks in the form of cherries, apricot and cherry, the last monilia is spreading the fastest. To save the trees you want to trim all the affected branches 5-10 cm from the fungus to healthy parts, then spray the whole tree "chorus", and weeks later to repeat the spraying, but other medication is "Emergency". Usually this treatment is enough to ensure that the tree died and in the following years bore fruit.
Is that cherry suddenly in the middle of summer begin to profusely fall off the leaves. Early leaf fall - a sign of kokkomikoza (fungal diseases). This fungus most often affects the leaves and fruit. First the leaves have small brown dots that grow into large spots, the lower part of the leaves is covered with white or pinkish bloom, the tree is losing leaves. The fruits in this condition are deformed, not ripen. Winters pathogen the fungus in the fallen leaves. To treat cherry is only necessary in late summer, after harvest. First needed around diseased trees to gather all fallen leaves and burn it, the soil is sprayed with urea solution (400 grams of urea per 10 liters of water). In the spring it is very important not to miss the "green cone" (Bud break) and processing 3% Bordeaux liquid, and immediately after flowering - a solution of 0.1% of topsin-M or 1% Bordeaux liquid.
The worst case - sudden shrinkage from the entire tree. The reason for this phenomenon - podpisanie the root collar. To save such trees is impossible, you can only prevent this disease. Since the cause of podpisania is the wrong tree planting, illiterate sampleviagra or watering, you only need to adjust watering, not to impose the trees are too thick layer of manure and try when planting not to bury the cuttings too deep.
