增效剂与氟啶虫酰胺协同作用防治小麦穗蚜

The synergistic effect of synergistic agent and fluridinamide to control wheat ear aphid

为科学推广农药减量控害技术,实现农药零增长,进行增效剂与氟啶虫酰胺协同作用防治小麦穗蚜试验。试验设6个处理,每个处理3次重复,随机区组排列;施药采用茎叶喷雾方式,用水量按450kg/hm^2。试验结果表明:施药后1d、7d、14d,10%氟啶虫酰胺WG750ml/hm^2与10%氟啶虫酰胺WG525ml+青皮桔油150ml/hm^2、10%氟啶虫酰胺WG525ml+青皮桔油180ml/hm^2、10%氟啶虫酰胺WG600ml+青皮桔油150ml/hm^2对麦穗蚜的防效相当,处理间差异不显著,前述四个处理对麦穗蚜的防效明显优于10%氟啶虫酰胺WG450ml+青皮桔油150ml/hm^2处理区,处理间差异达极显著水平。本试验中,在一定量的农药助剂青皮桔油的协同作用下,杀虫剂10%氟啶虫酰胺WG减量20%~30%,药后7~14d对麦穗蚜的防效仍可达94.3%~99.1%,与10%氟啶虫酰胺WG不减量单用的防治效果相当。药剂处理对小麦安全,不同处理对小麦都有一定的保产效果,小麦产量增幅在5.2%~7.4%之间。

In order to spread the pesticide quantity reduction and control technology scientifically,achieve zero growth in pesticides,the synergistic effect of synergistic agent and flonicamid on the control of wheat ear aphid was carried out.The experiment consisted of 6 treatments,repeated 3 times for each treatment,arranged in a random group;the application was carried out by spray of stem and leaf,and the water consumption was 450 kg/hm^2.The results show that:One,seven,and fourteen days after the use of pesticides,10% flonicamid WG 750 ml/hm^2,10% flonicamid WG525 ml+Qingpi orange oil 150 ml/hm^2,10% flonicamid WG525 ml+Qingpi orange oil 180 ml/hm^2 and 10% flonicamid WG600 ml+Qingpi orange oil 150 ml/hm^2 had similar control effects on wheat ear aphids.The difference between different treatments was not significant.The control effect of the first four treatments on wheat aphid was obviously better than that of10% flonicamid WG450 ml+Qingpi orange oil 150 ml/hm^2.The difference between treatments reached a very significant level.In this experiment,under the synergistic action of a certain amount of Qingpi orange oil,Even a 20-30% reduction in 10% flonicamid,the control effect of wheat aphid was 94.3-99.1% after the use of flonicamid 7-14 days,the effect of controlling aphid was similar to that of controlling aphid without reducing the amount of 10% flonicamid.Chemical treatment is safe for wheat.Different treatments can ensure the yield of wheat,They increased wheat production by 5.2% to 7.4%.
