2004～2006年进行田间12种药剂防治甜菜夜蛾、桃蚜的药效试验和室内毒力及生物活性测定。结果表明,在供试的防治甜菜夜蛾幼虫7种药剂中以溴虫腈的防效最高,药后5、7、14 d的防效分别为96.2%、99.1%、96.5%;氟铃脲和氟虫腈次之,药后5～14 d防效稳定在90%以上;高效氯氟氰菊酯和辛硫磷乳油再次之;阿维菌素、米满防效最低。在供试的防治桃蚜的6种药剂中以啶虫脒和吡虫啉防效较好,药后5～14 d校正防效均在90%以上;三氟氯氰菊酯、辛硫磷防效较低,在生产上应逐步减少使用。
From 2004 to 2006, 12 pesticides in the field were used to control Beet armyworm and Myzus persicae, and the indoor toxicity and bioactivity were determined. The results showed that the control effect of fipronil was the highest among the 7 insecticide beet armyworm larvae tested, the control efficacy was 96.2%, 99.1% and 96.5% on days 5, 7 and 14 after treatment respectively. And fipronil followed, 5 to 14 d after the drug efficacy and stability of more than 90%; lambda-cyhalothrin and phoxim again; avermectin, rice Man control effect of the lowest. Acetamiprid and imidacloprid were the best among the six pesticides tested against Myzus persicae and the corrected control efficacy was over 90% at 5 to 14 days after treatment. The control efficacy of cyhalothrin and phoxim was low, In production should be gradually reduced use.
