1997～ 1998年在许昌、漯河、三门峡、平顶山分别做了 10 %一遍净防治烟蚜的小区试验及大田示范。小区试验表明 :10 %一遍净可湿性粉剂防治烟蚜 ,每公顷喷 150～ 30 0 g对烟蚜防效均非常显著 ,对有翅蚜药后 1天防效为 6 2 %和 79% ,对无翅蚜防效为88%和 89%。药后 15天 ,对有翅蚜和无翅蚜防效仍可达 98%和 89%。 30 0 g/hm2 10 %一遍净大田防治示范表明 :移栽后 1个月之内对有翅蚜和无翅蚜都有显著防效 ,防效分别在 80 %～ 95%之内 ,10 %一遍净可湿性粉剂可在生产上大面积推广应用 1997 ~ 1998 in Xuchang, Luohe, Sanmenxia, ​​Pingdingshan made 10% of the net again to prevent the test of aphids and Daejeon demonstration field. The plot test showed that the control efficacy of 10% pure WP was better than that of the control, and the control effect was 150% ~ 300 g / ha. Effective control of wingless aphids was 88% and 89%. Fifteen days after treatment, the control efficacy against winged aphids and wingless aphids was still 98% and 89%. 30 0 g / hm2 10% The demonstration of prevention and control of net field showed that within 1 month after transplanting, there was a significant control effect on winged aphids and wingless aphids with the control effects being within 80% -95% and 10% Once again net WP can be widely applied in production
