【摘要】 为了筛选出防治花生蛴螬高效、低残留药剂,对15%毒死蜱颗粒剂(乐斯本)防治花生蛴螬进行了药效对比及用量试验,发现1 000、1 500、2 000g/667m2防效高于30%毒死蜱.辛硫磷乳油(邦得)和辛硫磷灌墩处理,荚果被害率最低,分别为10.84%、9.78%、8.86%;按防虫效果比较,15%毒死蜱颗粒剂(乐斯本)1 500、2 000g/667m2的防效与30%毒死蜱.辛硫磷乳油灌墩处理效果均达90%以上,比辛硫磷灌墩处理分别提高39.91和40.37个百分点。15%毒死蜱颗粒剂(乐斯本)1 000g/667m2即可达到理想的防治效果,且成本最低,花生荚果产量最高,纯增值495.1元,比辛硫磷和邦得纯增值分别提高147.6元和8.6元。因此15%毒死蜱颗粒剂(乐斯本)可替代高毒农药,一次施药即可控制蛴螬的危害,可在生产上大面积推广应用。更多还原

【Abstract】 In order to find the most effective,low residue pesticide to control white grub on groundnut,pharmic effect and dosage analysis were carried out on chlorpyrifos 15%GR and other two pesticide: Bangde(mixture of chlorpyrifos+phoxin)30% EC and Phoxim 40% EC.The results showed that the chhorpyrifos 15% GR was a effective pesticide to control white grub on groundnut.It could be a alternative product for replacement of high-toxicity pesticide.更多还原
