不同药剂对花生蛴螬的防治效果试验比较

摘要

Field trails of four pesticides for the control of peanut grub are carried out. The resulsts show that all four pesticides have good effets. The control effects of chlorpyrifos 30%CS with dosage of 1800g/hm^2, Phoxin 30%CS with dosage of 500g/hm^2, chlorpyrifos.Phoxin 30%EC with dosage of 500g/hm^2 and phorate-carbofuran 25%SC with dosage of 500g/hm^2 are all more than 82% after harvest. The four pesticides tested above are proposed to be used for control of peanut grub.%田间药效试验结果表明．供试验的4种杀虫剂对花生蛴螬均有较好的防治效果和速效性、持效性。收获后，毒死蜱30％微囊悬浮剂、辛硫磷30％微囊悬浮剂、毒·辛30％乳油和甲·克25％悬浮剂对花生蛴螬的防效均在82％以上。4种杀虫剂均可作为防治花生蛴螬的优良药剂。
