呋虫胺等几种新药剂防治水稻稻飞虱与黑尾叶蝉药效试验

通过田间试验,研究了呋虫胺等几种新药剂对稻田稻飞虱与黑尾叶蝉的防治效果。结果显示：80%烯啶·吡蚜酮WDG 150 g/hm^2、30%烯啶虫胺WDG 240 g/hm^2＋50%吡蚜酮WP 225 g/hm^2对稻飞虱的防治效果居前2位,在药后9-28 d,它们的校正防效达80.08%-96.23%;20%呋虫胺WDG 300-450 g/hm^2、30%烯啶虫胺WDG 300 g/hm^2、50%吡蚜酮150 g/hm^2＋20%呋虫胺WDG 300 g/hm^2对黑尾叶蝉的防治效果较佳,在药后15-28 d,它们的校正防效达94.54%-100%。...

The control effects of Dinotefuran and several new chemicals against rice planthopper and Nephotettix bipunctatus in paddy field were studied through field trials. The results revealed that 80% Nitenpyram·Pymetrozine WDG 150 g / hm^2 and 30%Nitenpyram WDG 240 g / hm^2＋ 50% Pymetrozine WP 225 g / hm^2 had better control effects on rice planthopper,and their corrected control effects reached 80. 08% - 96. 23% from the 9th to the 28 th day after application; 20% Dinotefuran WDG 300 - 450 g / hm^2,30% Nitenpyram WDG 300 g / hm^2,and 50% Pymetrozine 150 g/hm^2＋ 20% Dinotefuran WDG 300 g / hm^2 had better control effects on Nephotettix bipunctatus,and their corrected control effects reached 94. 54% - 100% from the 15 th to the 28 th day after application.
