摘要

为评价喷雾助剂对5％氯虫苯甲酰胺悬浮剂防治番茄潜叶蛾Phthorimaea absoluta Meyrick的增效作用,分别向比推荐用量减量10％、20％、30％的药液中添加有机硅Silwet 408、矿物油或芦荟精油助剂至终浓度为0.05％(V/V),测定其对番茄潜叶蛾的田间防效.结果显示,添加3种喷雾助剂均能不同程度地提高5％氯虫苯甲酰胺悬浮剂对番茄潜叶蛾的防效.相较于推荐用量,添加有机硅Silwet 408、矿物油或芦荟精油可使农药减量10％～20％.田间应用时可将5％氯虫苯甲酰胺悬浮剂按照推荐用量减量10％～20％,并添加有机硅Silwet 408、矿物油或芦荟精油来防治番茄潜叶蛾.

Abstract

To evaluate the synergism of spray adjuvants to chlorantraniliprole 5％SC against Phthorimaea absoluta Meyrick,control efficacies of chlorantraniliprole suspension solution at dosages of 90％,80％and 70％of the common dosage(recommended dosage)mixed with 0.05％(V/V)adjuvants(organosilicon Silwet 408,mineral oil or aloe essential oil additives)against P.absoluta were evaluated in the field.The results showed that adding three kinds of spray additives could improve the control efficacies of chlorantraniliprole,significantly higher than that without addition of spray additives.Compared with the common dosage,the dosage of insecticide could be reduced by 10％-20％by adding organosilicon Silwet 408,mineral oil or aloe essential oil.In practice,organosilicon Silwet 408,mineral oil or aloe essential oil are recommended to be mixed with chlorantraniliprole 5％SC,which would reduce the application amount of insecticide by 10％-20％.
