The question of why the cherry dries after flowering does not have an unambiguous answer. It is believed that a violent bloom weakens the tree, reduces its resistance against diseases. On the other hand, it is noticed that the abundant flowering of one specimen compared to the rest is a signal about the disease, and the last effort to prolong life, creating many seeds. Often, incorrect agricultural technology is the root cause of the disease.
Prerequisites for the disease
Wherever cherry orchards are cultivated in large areas, any infection spreads rapidly. Therefore, gardeners should alert the breeding grounds favorable for coccomycosis and moniliasis, weather conditions. Spring is cool and damp, which affects the duration of flowering. During the filling of berries warm and rainy, again a favorable environment for mushrooms. Only the prevention and disposal of the garden from insects will save the tree from the introduction of mycelium.
Cherries dry, what should I do? Any incomprehensible yellowing, drying does not happen spontaneously, it is a sign of the disease, most likely, fungal. The old uncleaned garden becomes a hotbed of many diseases. Gradually, they spread by insects and wind to neighboring plantations.
If there are preconditions, it is necessary to carry out preventive measures more often. But any treatment should be stopped 20 days before harvesting.
Prevention of disease
Healthy crop plants can only be cultured if agricultural practices are observed. Timely processing of cherry trees and shrubs from pests and diseases will kill the infection in the bud.
The tree receiving a full-fledged nutrition will be strong, there will be enough health reserves for flowering and pouring berries without harm to the crown. The resulting damage to the cortex should be immediately examined, disinfected and repaired. It is easier to prevent infection than to treat it with far from harmless methods. Why does a cherry blossom dry after a neighbor?
The answers are simple:
- The tree is planted on a hill or slope, well ventilated.
- The sapling was bought in a selection station resistant to monolithic varieties.
- Trees annually whiten, not only trunks, but skeletal branches. Each cracks on the bark are disinfected and covered with garden fumes so that there is nowhere for the spores to settle.
- The leaves are collected, the trunk circles are well-groomed.
- Branches are thinned according to the principle - the sparrow will fly.
Despite the cramped suburban area, the cherry must have a sufficient area of food.
In order to cherish the color and abundance of healthy berries, the tree should be properly planted and watered in a timely manner. Cherry does not like waterlogging and deep planting, roots can bend.
Spraying in certain periods is carried out as a prophylaxis against fungal diseases, which are introduced:
- in the open canaliculus of the flower;
- in a fresh wound on a broken branch;
- crack on the bark.
The flowers and twigs got sick, that's why the cherry dries after flowering.
Spores, bacteria, insect pests develop in a natural cycle. Therefore, it is impossible to process plants with drugs, as it turns out, there is a graph:
- immediately after the descent of the snow, cultivate the trunks and trees with 3% solution of the Bordeaux liquid or the Bordeaux mixture "Extra
- spraying with a 1% solution of copper sulfate on a green cone;
- Before the beginning of flowering cherry should be treated with Horus from moniliosis;
- During the vegetative period, do preventive treatment with drugs Abiga-Peak, Zato, Topsin, Horus.
Fungal diseases are introduced in the damp and cold period, with prolonged flowering. Take preventive measures is necessary, guided by the weather, not missing the favorable time.
Symptoms of diseases when the cherry dries after flowering
The storm of modern cherry orchards was the disease moniliosis, imported from America. It is a fungal disease on flowers in spring and on fruits before harvesting. A sign of the spring infection is that the leaves of the cherry dry after flowering, necrosis of the branches occurs. At this time, the mycelium quickly penetrates and infects the entire tree. Determine moniliosis can be found by cutting a branch of a dark ring.
The only correct solution is to cut all the branches 5-15 cm beyond the place of visible drying and burning of all plant residues. During the summer, the tree should be observed and continue to remove dried branches. Having destroyed the hearth, the next year should be prevented according to schedule.
The remaining on the branches of the fruit in the places of bites by insects are gray spore-bearing pads. They are located chaotically, and this differs from the gray fruit rot. Mummified fruits, fallen leaves will become a source of infection for the next year. If the disease is started, gray growths appear on the cortex.
It is important that on neighboring plantations, too, be careful to eradicate the infection. The disease itself will not go away, the tree will completely destroy. Systemic fungicides on spores of the fungus Monilia cinerea do not work.
Klyasterosporiosis or spotting - is also the reason why the leaves dry at the cherry. The disease manifests itself throughout the tree, including the roots. In this case, the buds of flowers and leaves turn black, fall off, the leaves become like a sieve. The cherries left on the branches are mummified and become carriers of the dispute. The mycelium is destroyed by copper oxychloride and Bordeaux mixture.
Cockcomicosis - the fungus actively reproduces after the flowering of the tree, and why the cherry dries. The signs of infection are red dots on the leaves from above, pink spores can be found on the back side. The leaves turn yellow, fall off, the pouring of berries ceases. If there are signs of a coccomicosis with a crop of the current year, it will be necessary to say goodbye. The tree in bloom needs to be treated,% with a solution of copper sulfate. If the harvest continues, after harvesting berries should be processed with Horus. Soak the soil with urea solution from the calculation of 40 grams per liter.
Only by carrying out a set of measures to preserve a healthy garden can you reduce the losses from fungal diseases.
