摘要
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 present study was conducted to control cabbage （Brassica oleracea L. var. capitata L. ） pests with several insecticides of 30 % chlorantraniliprole ·thiamethoxam SC, 25 % chlorantraniliprole SC and 40 % chlorpyrifos EC applied by drenching to seedbeds. The results showed that 30 % chlorantraniliprole · thiamethoxam SC had high control effect and longer duration against diamondback moth （Plutellaxy lostella） and striped flea beetle （Phyllotreta vittata） on cabbage. Ten days to twenty-five days after transplanting, the control efficacy of 30 % chlorantraniliprole · thiamethoxam SC was over 89 % , which was equal to 25 % chlorantraniliprole SC by 48.75 g.hm^-2 and very significantly better than that of other insecticides. Seventy days after transplanting, field investigations found that different treatments had significant different impacts on cabbage fruit setting. Among them, the effects of 30 % chlorantraniliprole·thia- methoxam SC had the lowest cabbage fruit setting rate.
