15%安打悬浮剂防治烟青虫药效试验

Experiments on Control of Heliothis assulta (Guenee) with 15%Abao-dall

进行了15%安打悬浮剂防治烟青虫试验,结果表明:用15%安打悬浮剂3000倍液药后3 d后虫口减退率可达100%,15%安打悬浮剂3500倍液药后3 d虫口减退率可达95.65%,明显优于氧化乐果500倍液和清水对照。一般从烟青虫发生初期进行防治,用药1～2次即可有效控制烟青虫的危害,建议生产上使用15%安打悬浮剂3000倍液。

Toxicity of Abao-dall against Heliothis assulta（Guenee） was tested on the field of Henan Agricultural University in 2008.The results showed that mortality was 100%in field spray with 3 000 - fold fluid of 15%Abao-dall after 3 days.The mortality was 95.65%in field spray with 3 500 -fold fluid of 15%Abao-dall after 3 days.If 3 000 - fold fluid of 15%Abao-dall prevent Heliothis assulta（Guenee） were used once or twice in initial stage,Heliothis assulta（Guenee）could be controued.
