摘要
应用4种绿僵菌、白僵菌、0.3%印楝素、1%苦参碱和森得保8种生物农药对草原蝗虫进行了田间药效对比试验,以期筛选出防效较好的生物农药用于大面积推广。研究表明,0.3%印楝素、1%苦参碱和森得保防治效果显著优于其他5种生物杀虫剂,药后11 d防效均在90%以上。几种杀蝗绿僵菌油悬浮剂药后11 d防效在65%以上,白僵菌油悬浮剂防效较差。杀蝗绿僵菌、印楝素、苦参碱和森得保几种药剂均为高效、低毒的生物农药和植物源农药,可以替代化学农药用于草原蝗虫的防治。
Experiments on the efficacy of 8 biocides for controlling grasshoppers were carried on in field,which included 4 types of Metarhisiums,Beauveria,0.3% Azadirachtin,1% Matrine and Sendebao,for screening out several good biocides to popularize in a large scale.The results of this study showed that the effect of 0.3% Azadirachtin,1% Matrine and Sendebao were better than that of other 5 biocides on controlling grasshoppers and their efficiency reached 90% on the 11th day after spraying in field.The effect of 4 types of Metarhisiums reached 65% on the 11th day after spraying and Beauveria was poorer.Metarhisium,Azadirachtin,Matrine and Sendebao can be used as substitutes for organic phosphorus and cycloprothrin pesticide in field due to their good-effect,low-poison and stemming from vegetation.
