Coccomycosis is a fungal disease. The main causative agent of the disease is a fungus that survives the winter period in leaves that have fallen in autumn, various plant residues. In the spring, its activation takes place. It is for this reason that it is necessary to remove all debris from the site as often and best as possible. Signs of the disease are the appearance of black spots on the berries, and you will also notice how the foliage begins to turn yellow and fall off ahead of time.
As a fight against the disease, you can spray the soil under the plant, as well as the tree itself, using products that contain copper. You can use copper sulfate, Bordeaux liquid, hom, oxychom, polychoma. You can take a 1% solution, in which one of the listed drugs is taken as a basis (for 5 liters of water, take 2 tablespoons of funds). Spraying is necessary in the spring and summer, after harvesting.
If you process the plant regularly, you can increase its lifespan. But, unfortunately, you will not be able to completely cure and restore the tree.
Also, Zircon is suitable for spraying. For use, you need to start preparing a highly concentrated solution. To do this, 1 capsule of the product must be dissolved in 2 liters of water. Spraying is carried out both on the soil and on the tree itself several times throughout the year: when the buds and buds begin to bloom, after fruiting ends. You can also use Fitosporin. This is a modern biological product. You need to prepare the solution based on the instructions. Spraying is necessary quite often and repeatedly: every 15-20 days throughout the growing season.

This disease has another name - gray rot. This disease is also fungal in nature. This fungus can arise as a result of weather conditions that positively affect the spread of the fungus - if it is damp, cool and the spring is pretty long.
The signs of the disease are that in the spring, when flowering begins, the leaves suddenly begin to darken, as well as young shoots. After which they begin to quickly fade and dry out. This happens in just a few days. The tree seems to be burning down before our eyes. Then the branches begin to grow again with leaves. And it would seem that everything is fine, and the problem is over. But with the onset of the summer period, everything repeats again. Infection of young shoots occurs from those that suffered in the spring. The fungus begins to penetrate the wood, the bark begins to be damaged.But the most important symptom of the disease is the appearance of black and gray dots and spots. The berries begin to crack and rot. It is impossible to eat them. Many people say that it is impossible to completely cure a tree that was infected, you can only prolong its life.
But the tree can be well supported by treatment with various special preparations. In the spring and in the first half of the summer period, it is necessary to spray the tree with Zircon. It is necessary to prepare a solution. To do this, 10 drops of the drug must be dissolved in 1 liter of water. The dose can be increased if you need to prepare a large amount of solution. It is necessary to spray the tree when the buds begin to bloom, before flowering begins, after flowering ends and after the entire crop has been harvested. In the spring, you can combine this drug with Epin-Extra. In August, it is imperative to remove dry foliage and spray the tree with copper-containing preparations (copper sulfate, homme, Bordeaux liquid, polychoma, oxychom). But all these procedures must be performed annually.

A symptom of this disease is the appearance of black dots and holes on the berry, right up to the bone itself. First, the insect begins to damage the foliage, and then moves on to the flowers and berries of the tree.
How to deal with this disease:
»It is necessary to dig all the soil under the tree. Then you can destroy a significant part of the insect larvae. The thing is that those berries that fall to the ground and carry the insect down so that it can survive the winter period without any problems.
»Those berries that have fallen from the tree must be removed and burned. After all, they can store insect larvae in themselves. It is best not to wait for the berries to fall to the ground themselves, but to remove the infected specimens directly from the tree itself.
»Carry out the treatment with the drug Akarin, having read the instructions in advance.
»Set a trap. With the onset of spring, the beetles become more active. They begin to crawl out of the soil in order to get enough of a tasty berry after a long winter period, as well as to lay their larvae in them in order to continue their offspring. It is best to prevent the appearance of insects, get ahead of them. Straw must be laid out in the trunk circle. This will be a kind of obstacle on the way for insects. insects simply cannot get out of the straw. Then the straw is simply burned. If the weevil has already settled on your tree, then you can simply shake it off. But before that, you need to lay out the film under the tree. This type of procedure is best done while the air temperature is no more than +10 degrees. throughout the spring, you can repeat such actions about 3 times in order to achieve the best effect.
