摘要
为达到农药减量增效的目的,采用纳米控失剂SC108、激健、强力源3种喷雾助剂与10%溴氰虫酰胺(OD)、10.5%三氟甲吡醚(EC)复配,通过室内毒力测定和大田防效试验,研究不同助剂与不同杀虫剂复配后对防治小菜蛾(Plutella xylostella L.)的减量增效作用。结果表明:①3种助剂均能对2种供试药剂起到较好的增效作用,其增效作用效果由大到小依次为强力源、纳米控失剂SC108、激健;②3种助剂均能使供试药剂减量20%~40%以上,其中以强力源表现最佳。
In order to achieve the purpose of reducing pesticide application and increasing efficiency the synergistic effects of three spray adjuvants including Nano loss control agent SC108,Jijian and Qiangliyuancombined with 10% cyantraniliprole OD and 10.5% pyridalyl EC against Plutella xylostella were measured,and field control effect test was also carried outin this paper.The results of indoor synergism showed that all the three spray adjuvant had good synergistic effects on the two tested pesticides.The synergistic effect from high to low was Qiangliyuan>Nano loss control agent SC108>Jijian.The field control effect test results showed that all the threespray adjuvants could reduce pesticide dosage by more than 20%~40%,but Qiangliyuan was the best.
