Prevention and control methods The proposed Rhizoma spinosa has a single feeding habit and is an important transmission medium for mulberry atrophy. (1) Reasonable fertilization, avoid late application, partial application of nitrogen fertilizer, heavy shearing during pruning in winter, cut 1/4 to 1/3 of new shoots, kill more than 50% of eggs. (2) Key prevention and control The first generation of eggs hatched in the incubation period, spraying 50% of malathion EC 800 times or 80% of dichlorvos EC 1000 times, 50% of CASS 600 to 900 times, 90% Crystal trichlorfon 1000 times. (3) Control and nymphs can be sprayed with 50% phoxim EC 2000 times or 40% Dimethoate 1500 times, 25% imidophos EC 1000 times, and 50% Malathion EC 1500 times. 10% imidacloprid wettable powder 2500 times, 48% chlorpyrifos EC 1300 times.
