【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。更多还原

【Abstract】 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.更多还原
