试验结果表明:247 g.L-1EngeoSC对大豆蚜虫具有良好的防治效果。施药后13、7、d,对大豆蚜虫的防治效果在88.5%-99.0%。在生产中,建议用247 g.L-1EngeoSC30 mL.hm-2或60 mL.hm-2,在大豆蚜虫发生期喷施。
The result showed that the control effect of 247 · L-1 EngeoSC on Aphis glycines Matsumura was quite high.Its control effect reached 88.5%~99.0% after using pesticide for 1、3 and 7 days.Proposing use 247 g·L-1 EngeoSC 30 mL·hm-2 or 60 mL·hm-2 when Aphis glycines Matsumura was occurring.
