摘要
除虫菊素为常用的植物源杀虫剂,对农作物害虫都有相关防治效果,且不易产生化学药剂抵抗、对环境友好,是理想的植物源杀虫剂。本试验中,5%除虫菊素防治效果稍弱于10%虫螨腈悬浮剂,而在5%除虫菊素各处理中,T2(稀释900倍5%除虫菊素)防治效果最好。在施药14d后,T2处理防治效果为30.25%。
As a common plant-derived pesticide,pyrethrin(extract of Pyrethrin cineriifoliun)shows a control effect on agricultural pests,is an environmentally friendly biological pesticide with less pest resistance.In this study,the control effect of 5%pyrethrin was investigated and it showed weaker control effectsthan that of 10%pyrethronil suspension.Among the tested treatments of 5%pyrethrin,T2(diluted 900 times with 5%pyrethrin)had the best control effect.After 14 days of application,the control effect of T2 treatment was 30.25%.
