摘　　要：50 g/L双丙环虫酯可分散液剂具有全新的结构和作用机制,是一种由天然产物衍生而成的新型生物源杀虫剂。为明确它对茶小绿叶蝉的防治效果,开展了50 g/L双丙环虫酯可分散液剂防治茶小绿叶蝉的田间试验。结果表明,药后1~14 d,15.00 g/hm^(2)和18.75 g/hm^(2)药剂的防效最高分别达到90.23%和92.17%。田间推荐使用剂量为15.00~18.75 g/hm^(2),使用时间为阴天或晴天下午4:00以后。The 50 g/Lafidopyropen dispersible liquid is a new biogenic insecticide derived fromnatural products,with a newstructure andmechanismof action.In order to clarify the difference in its control effect in tea green leafhopper,we carried out a field test to control tea green leafhoppers by the 50 g/L afidopyropen dispersible liquid.The results show that the maximumcontrol effects of 15.00 g/hm^(2)and 18.75 g/hm^(2)were 90.23%and 92.17%,respectively,from1 to 14 days after treatments.The recommended field dose is 15.00-18.75 g/hm^(2)on cloudy or sunny days and the use time is after 4 p.m.
