12种药剂对蛴螬的田间药效评价

为有效控制花生蛴螬危害,筛选高效、低毒、低残留的农药品种,选用12种不同杀虫剂,采用毒土处理方法进行田间药效试验。试验结果表明,供试的12种药剂中,30%辛硫磷微囊悬浮剂4050 g/hm2、30%毒死蜱微囊悬浮剂2250 g/hm2,对蛴螬防治效果分别为80.85%、78.73%,与3%克百威颗粒剂135 g/hm2、10%二嗪磷颗粒剂750 g/hm2差异不显著,但显著高于其它药剂,其对花生的保果效果分别为81.45%、80.99%,增产幅度分别为15.74%、12.71%,可作为替代高毒产品的理想药剂。

Assessment of Field Efficacy of 12 Different Pesticides against White Grub

We set a series of field experiment using application method of soil mixed with 12 different pesticides,in order to control white grub efficiency and screen out the pesticides of high-effect with low-toxicity and less-residual.The result showed,in the 12 different pesticides,the effects against white grub was 80.85% and 78.73% respectively when using 30% phoxim aqueous capsule suspension 4 050 g·hm-2 and 30% chlorpyrifos aqueous capsule suspension 2 250 g·hm-2,there was significant difference when compared with 3% carbofuran granules 135 g·hm-2 and 10% diazinon granules 750 g·hm-2,but significantly higher than other pesticides,the protection effects on peanut was 81.45% and 80.99% respectively,the yield of peanut was increased by 15.74% and 13.71 respectively,significantly higher than other 10 pesticides,so both of the two pesticides can be chosen as the ideal pesticide to replace the highly toxic pesticides.
