| 基于兼治水稻害虫二化螟、稻纵卷叶螟和稻飞虱的杀虫单剂缺乏的现状, 2014-2015年采用田间小区试验评价了三氟苯嘧啶与氯虫苯甲酰胺、溴氰虫酰胺、甲氧虫酰肼、茚虫威、阿维菌素或甲氨基阿维菌素苯甲酸盐混配以及吡蚜酮与氯虫苯甲酰胺混配对以上几种害虫的防治效果。结果表明, 三氟苯嘧啶与氯虫苯甲酰胺混配最为理想, 能有效控制二化螟、稻纵卷叶螟和稻飞虱为害; 药后14~21 d对二化螟和稻纵卷叶螟的防治效果分别为89.40%~93.62%和86.57%~90.81%, 药后42 d对稻飞虱的防治效果为77.60%~82.24%。其次为三氟苯嘧啶与溴氰虫酰胺混配, 对二化螟和稻飞虱高效且兼治稻纵卷叶螟; 药后14~21 d对二化螟和稻纵卷叶螟的防治效果分别为80.43%~86.75%和67.31%~75.30%, 药后42 d对稻飞虱的防治效果为79.07%~84.30%。三氟苯嘧啶与甲氧虫酰肼、茚虫威、甲氨基阿维菌素苯甲酸盐或阿维菌素混配对稻飞虱高效, 但难以有效控制二化螟和稻纵卷叶螟为害。而吡蚜酮与氯虫苯甲酰胺混配对二化螟和稻纵卷叶螟高效, 但后期对稻飞虱的控制作用一般。在水稻生产实践中, 使用三氟苯嘧啶与氯虫苯甲酰胺或溴氰虫酰胺混配, 可有效控制二化螟、稻纵卷叶螟及稻飞虱为害。 |
| 英文摘要: |
| Because of the scarcity of single insecticide for the control of the striped stem borer, Chilo suppressalis, rice leaf-roller, Cnaphalocrocis medinalis and rice planthoppers, field plot experiments were conducted to evaluate control efficacy of triflumezopyrim plus chlorantraniliprole, cyantraniliprole, methoxyfenozide, indoxacarb, abamectin or emamectin benzoate, and pymetrozine plus chlorantraniliprole against above several pests in 2014-2015. The results showed that an excellent multi-target insecticides mixture, triflumezopyrim plus chlorantraniliprole gave perfect control against C. suppressalis, C. medinalis and rice planthoppers. The control efficacies of the mixture against C. suppressalis and C. medinalis were 89.40%-93.62% and 86.57%-90.81%, respectively, 1421 d after treatment; control efficacies against rice planthoppers were 77.60%-82.24% 42 d after treatment. A better multi-target insecticides mixture, triflumezopyrim plus cyantraniliprole, also demonstrated perfect control against C. suppressalis and rice planthoppers, and better control against C.medinalis. The control efficacies of the mixture against C.suppressalis and C.medinalis were 80.43%-86.75% and 67.31%-75.30%, respectively, 1421 d after treatment; and the control efficacies against rice planthoppers were 79.07%-84.30% 42 d after treatment. Rice planthoppers were obviously controlled by triflumezopyrim plus methoxyfenozide, indoxacarb, abamectin or emamectin benzoate, but C. medinalis and C. suppressalis were not. However, pymetrozine plus chlorantraniliprole controlled C. medinalis and C. suppressalis effectively but modestly for rice planthoppers at the late-stages of rice. These results suggested that the triflumezopyrim plus chlorantraniliprole or cyantraniliprole could be recommended for control of C. suppressalis, C. medinalis and rice planthoppers during the process of rice production. |
