乙基多杀菌素等5种药剂对设施甜瓜上蓟马的防效试验

Control Efficacy of Five Different Insecticides on Thrips of Melon in Facility Cultivation

为了筛选防治三亚地区设施甜瓜蓟马的药剂,选取目前国内常用的5种药剂进行田间试验。试验结果表明,60 g/L乙基多杀菌素悬浮剂的防效最好,最高达到了99.17%;其次为10%虫螨腈悬浮剂,最高防效为70.47%;25 g/L多杀霉素悬浮剂、70%吡虫啉水分散粒剂和25%噻虫嗪水分散粒剂防效比较差,最高防效分别为58.40%、53.34%和52.85%。

The trial was carried out to screen out the best insecticide to control melon thrips in the facility cultivation from five insecticides.The results showed that the insecticide 60 g/L spinetoram suspension concentrate（SC） possessed the highest control efficiency of 99.17%,and 10% chlorfenapyr SC took the second place with the highest control efficiency of 70.47%,while the other three insecticides 25 g/L spinosad SC,70% imidacloprid water dispersible granules（WG） and 25% thiamethoxam WG had worse control efficiency,which were only 58.40%,53.34% and 52.85% respectively.
