20 0 1年在昭通市昭阳区北闸镇开展了灭蚜宁防治烟蚜的小区试验和大田示范。小区试验结果表明 :灭蚜宁 5 0 0～ 15 0 0倍防治烟蚜效果均显著 ,药后 10d防效达 99.0 3%以上、药后 2 0d防效达93.96 %以上。大田示范表明 :用 75 0g/hm2 的灭蚜宁 10 0 0倍防治烟蚜平均防效为 96 .6 9%。灭蚜宁防治烟蚜防效显著 ,可在烤烟生产上全面推广使用。
In 2001, Zhaotong City Zhaoyang District North Gate Township carried out aphid-killing aphid-killing plot test and Daejeon demonstration. The plot test results showed that the effect of controlling aphids was 100% ~ 150 times higher than that of control, and the control effect was over 99.0% after 10 days. The control effect reached 93.96% after 20 days. Daejeon demonstrated that the control effect of aphids was 96.69% with 100 0 times amber amber of 75 0g / hm2. Aphis citric aphids control pest control effect is significant, can be fully promoted in the production of flue-cured tobacco.
