灭蚜宁防治烟蚜药效试验

Experiments on Control of Myzus persicae (Sulzer)with a Biological Insecticide, Mieyaning

摘要: 2001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500~1 500倍防治烟蚜效果均显著,药后10d防效达99.03%以上、药后20d防效达93.96%以上。大田示范表明:用750g/hm²的灭蚜宁1 000倍防治烟蚜平均防效为96.69%。灭蚜宁防治烟蚜防效显著,可在烤烟生产上全面推广使用。

Abstract: Field and plot experiments on control of Myzus persicae (Sulzer)with a biological insecticide, Mieyaning WP, were conducted in 2001.The results showed that the plot control effects of Mieyaning at a dilution of 500~1 500 were over 99.03% and 93.96% for 10 days and 20 days after application, respectively, and the field demonstration showed an average control effect of 96.69% by application of Mieyaning (dilution 1 000)at a rate of 750g/ha.
