| 摘 要： | 室内生测结果表明:吡蚜酮与异丙威质量比为1∶2,对褐飞虱3龄若虫具有较高的生物活性,其LC50值为11.01 mg/L,共毒系数为166.65,表现出明显的增效作用;按此配比加工成30%吡蚜·异丙威WP(有效成分:吡蚜酮10%、异丙威20%).田间防治结果表明:该混剂对褐飞虱表现出良好的速效性和持效性.药后3 d,30%吡蚜·异丙威WP 450～600 g/hm2对褐飞虱若虫的防治效果为90.83%～94.94%,药后21 d,30%吡蚜·异丙威WP 450～600 g/hm2对褐飞虱若虫的防治效果仍有87.60%～89.32%,均好于对照药剂吡蚜酮、异丙威对褐飞虱的防治效果.从防效和经济的角度考虑,30%吡蚜·异丙威WP推荐剂量为450 g/hm2,防治适期宜在褐飞虱若虫高峰期.

| Abstract: | The result of the biological activity showed that the LC 50 and co-toxicity coefficient(CTC)of the mixture of pymetrozine and isoprocarb at the ratio of 1:2,which had excellent effect against the 3 th larval stage of Nilaparvata lugens,were 11.01 mg/L and 166.65,respectively.The mixture indicated addition effect,obviously.The results of field trials of pymetrozine and isoprocarb 30%WP which content pymetrozine and isoprocarb at the ratio of 1:2,showed that the mixture reagent had favorable quick-acting and ... |
