为筛选经济有效安全药剂防治稻纵卷叶螟,对20%氯虫苯甲酰胺(康宽)SC、10%氟虫双酰胺·阿维菌素(稻腾)SC、生物农药病毒增强Bt WP 以及甲维盐WG等几种杀虫剂进行田间药效试验,结果表明,20%氯虫苯甲酰胺SC、10%氟虫双酰胺·阿维菌素SC药剂防治稻纵卷叶螟用量分别为10 mL/667m2、30 mL/667m2时,在药后7 d的保叶效果分别为88.6%、79.7%,在药后14 d的保叶效果分别为90.9%、86.2%.20%氯虫苯甲酰胺SC、生物农药病毒增强Bt WP、200 g/667m25.7%甲维盐WG在药后7~14 d用量分别为10 mL/667m2、200 g/667m2、14 g/667m2时,对稻纵卷叶螟的防治效果分别为89.0%~100%、53.2%~88.3%、84.4%~97.7%,防效均超过80%;另外,1.8%阿维菌素EC 50 mL/667m2在药后14 d对稻纵卷叶螟的防效由药后7 d 76.7%上升为81.2%,可见,以上几种药剂均能作为防治稻纵卷叶螟的较理想药剂.

In order to effectively control Cnaphalocrocis medinalis, we chose 20% chlorine benzamide (Kangkuan) SC, 10%fipronil bisamide?avermectin (Daoteng) SC, Bt WP and avermectin benzoate WG to control Cnaphalocrocis medinalis in field trials. The results showed that 7 days after application, the effects of Kangkuan at 10 mL/667m2and Daoteng at 30 mL/667m2 were 88.6%and 79.7%, respectively. After 14 days of application, the effects of the Kangkuan and Daoteng were 90.9%and 86.2%, respectively. The insecticidal effects of, Daoteng at 10 mL/667m2, Bt at 200 g/667m2 and avermecin benzoated WG at 100 g/667m2 were 89.0%to 100%, 53.2%to 88.3%, 84.4% to 97.7%, respectively, at 7 to 14 days after application. The control efficiency of those 4 insecticides were higher than 80%. In addition, the efficacy of 1.8%avermectin EC at 50 mL/667m2 increased to 81.2%from 76.7%14 d after application.
