摘要
室内毒力测定结果表明 ,阿·苏 WP对小菜蛾有明显的增效作用 ,其共毒系数为 15 0 .1。大田试验结果表明 ,阿·苏 WP112 5～ 15 0 0 g· hm-2药后 3d对小菜蛾防效为 6 6 .3%～ 85 .2 % ,药后 7d达86 .1%～ 95 .6 %。
The results of toxicological test showed that abamectin-Bacullus thuringiensis WP had remarkable synergistic effect on Plutella xylostella L in green-house, and its co-toxicity coefficient was 150 1 The control effect against Plutella xylostella L was 66 3%～85 2% on the third day after treatment, 86 1%～95 6% on the 7th day after treatment at the rate of 1125～1500ghm -2 in field
