摘要
试验测定了8种杀虫剂对甘蓝小菜蛾的田间防治效果.结果表明:15%唑虫酰胺悬浮剂、30%虫螨腈悬浮剂、10%溴氰虫酰胺可分散油悬浮剂和5%氯虫苯甲酰胺悬浮剂药后3d防效＞83%,且药后10d防效＞90%,具有较好的持效性,可有效防治甘蓝小菜蛾.150 g/L茚虫威悬浮剂药后3d防效达89.22%,药后10d防效降到84.93%,具有较好的速效性.10%虱螨脲悬浮剂和5%氟铃脲乳油药后3d防效为75.09%～77.14%,药后10d防效有较大的提高,达到83.99%～87.03%,药效作用较缓慢.5%甲氨基阿维菌素苯甲酸盐水分散粒剂药后3d防效为80.46%,药后10d防效为83.98%,防治效果偏低.各试验药剂对甘蓝安全,对其他有益生物无不良影响.
Abstract
The field efficacy of eight insecticides against Plutella xylostella was tested.The results showed that the control effects of 15% tolfenpyrad SC,30% chlorfenapyr SC,10% cyantraniliprole OD and 5% chlorantraniliprole SC on P.xylostella were more than 83% at 3 days after application and more than 90% at 10 days after application,demonstrating good durability and effectively control of P.xylostella.The control effect of 150 g/L indoxacarb SC was 89.22% at 3 days after application,and 84.93% at 10 days,showing good rapid effect.At 3 days after treatment,the control effects of 10% lufenuron SC and 5% hexaflumuron EC were 75.09%～77.14%,and at 10 days,the control effect improved greatly,reaching 83.99%～87.03% .The control effect of 5% emamectin benzoate WG was 80.46% at 3 days after treatment and 83.98% at 10 days after treatment.All tested chemicals were safe for cabbage and had no adverse effects on other beneficial organisms.
