小菜蛾是危害十字花科蔬菜的重要害虫,为了推广高效低毒杀虫剂,特开展了苏云金杆菌与茚虫威两种低毒杀虫剂桶混防治小菜蛾的田间药效试验。试验结果表明,8 000IU/μL苏云金杆菌悬浮剂与150g/L茚虫威悬浮剂按(75+18)mL/667m~2用量桶混后对防治小菜蛾具有较好的防治效果,较苏云金杆菌单剂具有高效、速效、持效期长的特点,且毒性较低,对甘蓝安全,是防治小菜蛾的理想使用方法。
Plutella xylostella is an important pest that endangers cruciferous vegetables. In order to popularize high-efficiency and low-toxicity insecticides, field trials on the control of Plutella xylostella by combining two low-toxicity insecticides such as Bacillus thuringiensis and indoxacarb were carried out. The results showed that 8 000 IU / μL Bacillus thuringiensis suspension concentrate and 150 g / L indoxacarb suspension mixed with (75 + 18) mL / 667m ~ 2 had good control effect on the control of Plutella xylostella, The single agent has the characteristics of high efficiency, quick-acting, long-lasting effect, low toxicity and safety to cabbage, which is an ideal method for controlling diamondback moth.
