摘要
[目的]筛选防控刺梨白粉虱的药剂。[方法]选取5种高效低毒化学杀虫剂开展对刺梨白粉虱的田间防效试验,并评价施药后对刺梨品质和产量的影响。[结果]60%呋虫胺WG和50%噻虫胺WG对刺梨白粉虱的综合防效及对刺梨品质和产量的提升效果较好,药后3 d防效均超过89%,药后7 d防效均在90%以上,其中50%噻虫胺WG的防效达95.93%,药后14 d 60%呋虫胺WG的防效降幅最小。[结论]推荐60%呋虫胺WG和50%噻虫胺WG作为防控刺梨白粉虱的药剂。
[Aims] This study aims to screen out the chemicals for preventing and controlling Trialeurodes vaporariorum of Rosa roxburghii Tratt. [Methods] Five high-efficiency and low-toxicity chemical insecticides were selected to carry out the field control experiment on T. vaporariorum of R. roxburghii, and the effects on the quality and yields of R. roxburghii were evaluated. [Results] The comprehensive control effect of dinotefuran 60% WG and clothianidin 50% WG on T. vaporariorum of R. roxburghii were better, and the control effect of dinotefuran 60% WG was over 89% after 3 days and over 90% after 7 days. Among them, the control effect of clothianidin 50% WG reached 95.93%, and the control effect of dinotefuran 60% WG decreased the least at 14 days after spraying pesticide. [Conclusions] Dinotefuran 60%WG and clothianidin 50% WG are recommended as agents to prevent and control trialeurodes of R. roxburghii.
