近几年,水稻褐飞虱在华东、华南等大部分稻区连年重发,一般药剂防治效果不理想,不同程度地影响了水稻生产。试验结果表明,25%吡蚜酮WP等药剂对褐飞虱具有较好防治效果,2006年开始大面积推广应用后,取得了十分显著的控害保苗效果。
In recent years, Nilaparvata lugens (Nilaparvata lugens) repeats in successive years in most of east, south and other areas in China. The general control effect is not satisfactory, which affects rice production in varying degrees. The results showed that 25% pymetrozine WP and other pesticides had good control effects on N. lugens. After large-scale popularization and application in 2006, a very significant control effect on seedling conservation has been achieved.
