Gardeners often face a problem: during harvesting, raspberries crumble right in their hands.
The reason for this phenomenon is the virus of the rassypukha. The infectious agent, getting into the plant, disrupts the process of fruit formation.
The berries form few drupes, they are weakly connected to each other. Therefore, when picking berries, you do not get a whole fruit in your hands, but a scattering of small "balls".
What to do
Fertilizers and treatments will not help. Radical action will have to be taken. It is necessary to dig up the affected bushes and destroy them.
It is important to get rid of not only the above-ground part, but also to remove as many roots from the ground as possible.
Viral plant diseases are incurable, but they spread very quickly and easily.
Preventive measures
1. High-quality seedlings purchased from a certified nursery.
2. You cannot plant raspberries in the place where a diseased plant grew for several years.
3. Weed control. They are a reservoir of various viruses. The spread of pests (aphids, leafhoppers, etc.) begins with weeds. Insects transfer infected material from grass to crops.
