Last year, I encountered such a problem as a spider mite on raspberries. I grow a plant for only 2 years, I didn’t know anything about this pest. While the berries were being sung, I plucked the damaged leaves, sprayed with salt water. After harvesting, she immediately processed Fufanon. Raspberries came to life in a week. In the spring I did the treatment again, I didn’t see any more parasites on raspberries.
