摘　　要：为降低农药使用量,提高农药效能和生态效益,开展了不同增效助剂的田间筛选试验。从末次药后7 d防效看,烯酰吗啉减量40%+纳米控失剂处理的防效为63.38%,14 d后防效高达100.00%,明显高于其他处理;同时,烯酰吗啉减量40%+有机硅处理14 d后的防效也达到100.00%;4种增效助剂均不同程度地增强和延长了药效。综合分析结果表明:烯酰吗啉减量40%+助剂组合效果较好,助剂中又以纳米控失剂、有机硅增效显著。In order to reduce the pesticide usage and improve the effectiveness and ecological benefits of pesticides,field screening trials of different effective adjuvents have been carried out.According to the control effect 7 days after the last treatment,the control effect of dimethomorph reduction by 40%+nano-loss control agent treatment was 63.38%,and the control effect after 14 days was as high as 100.00%,which was more significant than other treatments.At the same time,the control effect of dimethomorph reduction by 40%+organic silicon treatment after 14 days was also as high as 100.00%.The four effective adjuvents have enhanced and prolonged the efficacy to varying degrees.According to the comprehensive analysis results,the effect of dimethomorph reduction by 40%+adjuvant combination was better,and among the adjuvants,nano-loss control agent and organicsilicon have a significant effect.
