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 indoor toxicity test showed that Arabidopsis WP had obvious synergistic effect on Plutella xylostella and its co-toxicity coefficient was 150.1. The results of field trials showed that the control efficacy against P. xylostella was 56.3% ~ 85.2% after A. suva WP112 5-1500 g · hm-2 for 3 days and reached 86.1% ~ 95% on the 7th day after treatment. 6%.
