Having discovered spots and holes on cherry leaves, inexperienced gardeners may not attach any importance to this, and completely in vain.
This is the first sign of a tree being affected by one of the serious fungal diseases of stone fruit crops – apricots, peaches, cherries, cherries and plums.
What to look out for
The first thing that should alert the gardener is small light-brown spots. In 2-3 days they will be decorated with a reddish border. The spots from 2-3 mm will grow to 0.5 and even 1 cm, and in a couple of weeks through holes will appear. This is clasterosporium.
The affected foliage dries up and falls off. Then the disease spreads to the fruit - they will develop purple spots or dents, which will quickly turn into a crust and the berries will grow crooked.
During the flowering stage, the disease causes buds and flowers to fall off.
Prevention
It is necessary to carry out sanitary pruning, remove dry damaged shoots. Treat cuts with garden pitch or 1% solution of copper sulfate.
Before the buds open, the tree is treated with a solution of copper sulfate.
Treatment
The disease cannot be stopped without fungicides. The preparations used are "Abiga-Peak", "Skor" or a 1% solution of Bordeaux mixture.
The first treatment is carried out in early spring, and the second after flowering. The third one is carried out in a week.
The treatment is repeated a month before harvesting.
In advanced cases, after the autumn leaves fall, the cherry is treated with a 3% Bordeaux mixture.
