The Prevention and Treatment of Two-Star Leafhoppers
Agricultural control: Remove defoliation and dying grass in the orchard to kill overwintering adults, remove weeds in the growth period, and maintain good ventilation and light transmission conditions.
Chemical control: Combine and prevent other diseases before germination to spray over 5 adult stone sulfur compounds to eliminate overwintering adults. The first generation nymphs were sprayed with 50% dichlorvos 800 times, or 10% imidacloprid WP 4000-6000 times, and 20% chlorfluthrin 2000 times.
