研究了30%氯虫.噻虫嗪SC、25%氯虫苯甲酰胺SC、25%噻虫嗪WG及40%毒死蜱EC等药剂苗床灌根对结球甘蓝害虫的控制效果。结果表明,30%氯虫.噻虫嗪SC对小菜蛾与黄曲条跳甲高效且持效期长,移栽后10～25d各处理防效都很好,均大于89%,与25%氯虫苯甲酰胺SC48.75g.hm-2处理的防效相当,但极显著优于其他药剂处理。移栽后70d田间调查发现,不同处理对甘蓝结球的影响存在明显差异,其中30%氯虫.噻虫嗪SC结球率最低,空白对照结球率最高。
The control effects of 30% Chlorantranilon, Thiamethoxam SC, 25% Chlorantranilon SC, 25% Thiamethoxam WG and 40% Chlorpyrifos EC on the control of cabbage pests were studied. The results showed that Thiamethoxam 30% was effective and long-lasting for Plutella xylostella and Dipterocarpaceae, and the control effect was very good at 10-25 days after transplanting, both of which were more than 89% Chlordimeform benzamide SC48.75g.hm-2 treatment control effect is quite, but very significantly better than other pharmaceutical treatment. 70days after transplanting field survey found that different treatments on the cabbage ball there is a significant difference, of which 30% Chlordimes. Thiamethoxam SC the lowest rate of the ball, the highest percentage of blank control.
