DISEASES AND PESTS OF CHARCOAL
© Author: Nikolai CHROMOV
Quite recently, some 50-60 years ago, cherry plum was considered an exclusively southern culture, even in the central regions, where winters, as a rule, are not too harsh, it froze out. With the development of the breeding culture, many varieties appeared, the fruits of which are juicy and tasty, and the plants themselves are able to withstand frosts up to 45 C. Such varieties are resistant to drought and practically not damaged by pests and diseases, but such troubles still happen ...
Small spots of yellow-brown color on the leaves, leading to the gradual drying of the leaf and their premature abscission. You can fight by collecting and destroying (burning) plant residues, processing with 1% copper sulfate (50 g per Yul of water).
Spraying is carried out in early spring, before bud break. Good results are obtained by treatment with Bordeaux liquid (70 g per 10 l of water). This treatment must be carried out in the green cone phase or in the bud extension phase. Re-processing is carried out immediately after flowering. In case of severe damage, additional treatments with HOM are also necessary, they are carried out two weeks after flowering, and the last one - three weeks before harvesting.
MONILIOSIS OF CHARCOAL
Shoots and even whole branches turn brown and wither, giving the impression of being burnt. In the future, growths form on the bark. Affected fruits rot, and gray growths form on their surface. The branches crack and die. Pruning and burning affected shoots and fruits, treating the soil with 1% iron or 2% copper sulfate, as well as 1% Bordeaux liquid before flowering will help to resist the disease. The second treatment is carried out immediately after the end of flowering, using 1% Bordeaux liquid (80 g per 10 l of water). HOM preparation is also suitable for processing.
Withering away of plum branches
Pinkish warty growths on the bark lead to the death of the shoots. You can fight by pruning and burning affected shoots. Cut the wounds to healthy tissue and cover with garden varnish.
Caterpillars eat up passages in young shoots, reaching the lignified part. Damaged shoots become brittle and often dry out. In addition to shoots, caterpillars also consume fruit pulp. Treatment with a solution of sodium chloride (500-700 g per 10 liters of water), which is carried out immediately after flowering, will help to get rid of them. For one adult plant, at least 7 liters of solution are needed, for a young plant - 1,5-2 liters. It is useful to repeat the treatments after harvest.
FRUIT FATHERLANDS AND WESTERN NON-PAIRED BOX
Females gnaw through passages in the wood and bark of trees, laying eggs in them. Weakened or frost-damaged shoots are more often affected. Pruning and burning affected shoots in early June will help to cope with the pest.
Caterpillars make moves in the wood, leading to the death of shoots or individual branches. Whole trees die when severely damaged. It can be dealt with by removing and burning damaged shoots outside the territory of the site. If only small areas are damaged on the shoots, then they can be cleaned to healthy tissue and covered with garden varnish.
