99%绿颖乳油对稻纵卷叶螟、二化螟、稻飞虱的控制效果试验

Effects of 99% EnSpray EC on controlling leaf folder(Cnaphalocrocis medinalis G.),strip borer(Chilo suppressalis W.) and planthopper in rice

进行99%绿颖乳油单用及与常规化学农药减量混用后对水稻主要害虫的控制效果试验,结果表明,99%绿颖乳油与常规防治农药5%锐劲特悬浮剂减量混用后增效明显,每公顷5%锐劲特悬浮剂300mL+99%绿颖乳油1500mL药后对稻纵卷叶螟、二化螟、稻飞虱有较好的控制效果,与5%锐劲特悬浮剂600mL药效无显著差异;99%绿颖乳油3000mL单剂处理,对稻飞虱有较好的控制效果,对稻纵卷叶螟、二化螟也有一定的控制能力。

In the experiment, 99% EnSpray EC and the mixture of EnSpray and conventional chemical pesticide were applied to control the main insect pests of rice. The results indicated that the mixture of 99% EnSpray EC and 5% Regent suspending agent had significant effects on the pests control of rice. When the mixture of 300mL/hm^2 Regent and 1500 mL/hm^2 99% Enspray EC was applied in field plot trials, it showed excellent control effects on leaf folder, strip borer and planthopper, which had no significant difference with 600 mL/hm^2 5%Regent. When 3000 mL/hm^2 99 % EnSpray EC was alone applied in field plot trials, it showed good control on planthopper, and it also could inhibit leaf folder and strip borer.
