摘要
试验分别用3g／L的3种生物碱水溶液单剂及复配方药液为试药，在6种经济作物，2种害虫上进行毒杀效果研究。结果表明：3种单剂对蚜虫均有生物活性，其复配方药液对害虫的毒杀增效作用显著，药后3～5d防效达90％以上，田间持效期长，延长到7．15d。它们是理想的防治枸杞蚜、蔬菜蚜和菜青虫的无公害药剂。
The effects of three 3 g/L alkaloid single aqueous solutions and compound solutions on two pests in six cash crops were studied. The results showed that all the three single doses had insecticidal activity against aphid, and the compound solution significantly increased the effectiveness of insecticidal action. The effect was up to 90% in 3～5 days after the application, and the effective duration was prolonged to 7 ～ 15 days. It could be recommended as an ideal bio -rational pesticide against aphid and cabbage worm.
