为了探讨毒死蜱.甲胺基阿维菌素苯甲酸盐对稻纵卷叶螟的防治效果。在随机区组设计的田间试验中,在稻纵卷叶螟低龄幼虫高峰期,采用20%毒死蜱.甲胺基阿维菌素苯甲酸盐WP 7509、001、050 g/hm2,48%乐斯本EC 900 ml/hm2,1%甲胺基阿维菌素苯甲酸盐EC 225 ml/hm2和清水对照(CK)6个处理,通过施药前的基数调查和药后7 d的药效调查,研究了毒死蜱.甲胺基阿维菌素苯甲酸盐对稻纵卷叶螟的防治效果。药后7 d,用20%毒死蜱.甲胺基阿维菌素苯甲酸盐WP 7509、001、050 g/hm2,对稻纵卷叶螟的防效分别为79.9%、85.1%和86.8%,对二化螟的防效分别达64.1%、78.8%、85.7%。20%毒死蜱.甲胺基阿维菌素苯甲酸盐可湿性粉剂对稻纵卷叶螟有良好的防治效果,兼治二化螟,且对水稻生长安全。
In order to investigate the control effect of chlorpyrifos-emamectin benzoate on rice leaf roller. In the field trial of randomized block design, 20% chlorpyrifos was used at the young larvae of C. medinalis and methamidophos benzoate WP 7509,001,050 g / hm 2, 48% Six treatments were applied with 900 ml / hm 2 of Swainson EC and 225 mg / hm 2 of emamectin benzoate EC and CK (CK) Effectiveness of chlorpyrifos and emamectin benzoate for control of rice leaf roller Cnaphalocrocis medinalis was investigated. Seven days after the treatment, 20% chlorpyrifos, emamectin benzoate WP 7509,001, and 050 g / hm2 were 79.9%, 85.1% and 86.8% , The control effect on the stem borer reached 64.1%, 78.8%, 85.7% respectively. 20% chlorpyrifos. Emamectin benzoate wettable powder has good control effect on Cnaphalocrocis medinalis, treats Chilo suppressalis, and is safe for rice growth.
