摘要
[目的]筛选对棕榈蓟马有较好防治效果的药剂。[方法]用浸叶法开展了40%辛硫磷EC对棕榈蓟马的室内毒力测定,并进行了田间药效试验。[结果]辛硫磷对棕榈蓟马成虫的LC50值为6.881mg/L,40%辛硫磷EC用量900～1125kg/hm2对棕榈蓟马具有较好的防治效果。[结论]40%辛硫磷EC是防治设施蔬菜棕榈蓟马的较好药剂,生产上可以推广应用。
[Objective] The aim was to screen the pesticide with good control effects of Thrips palmi.[Method] The toxicity of 40% phoxim EC against Thrips palmi were evaluated by leaf-dipping method in the lab and field trials were carried out.[Result] The LC 50 of phoxim against T.palmi adult were 6.881 mg/L and the control effects of T.palmi were better when the dosages of 40% phoxim EC were 900 ～1 125 kg/hm 2.[Conclusion]40% phoxim EC was the excellent pesticide for controlling Thrips palmi,and it could be used in application and dissemination of vegetabble production.
