摘要
以盆栽黄瓜为供试植物,利用灌根法,研究了5种杀虫剂对黄瓜烟粉虱的防治效果。结果表明:阿维菌素对黄瓜烟粉虱最高防效不足30%,吡虫啉、噻虫嗪、啶虫脒和烯啶虫胺灌根施药后7d,防效均在60%以上,10d防效达最高,其中吡虫啉130mg/L处理防效最高为94.3%,持效期长达20d。本研究为黄瓜烟粉虱防治药剂的合理使用提供了科学依据。
The control effect of five insecticides against white flies Bemisia tabaci were examined with root pouring on cucumber plants in greenhouse.The results showed that the control effect of abamectin against B.tabaci was less than 30%.On the contrary,the control effects of imidacloprid,thiamethoxam,acetamiprid and nitenpyram were all more than 60% 7d after application,and reached a high level at 10d.The control effect at 10d of imidacloprid,at the dose of 130mg/L,was up to 94.3%,and its efficacy could prolong to 20d.This study provides a scientific basis for the reasonable application of insecticides against B.tabaci on the cucumber plants.
