几种颗粒剂防治草坪地下害虫蛴螬效果研究

研究四种颗粒剂对草坪地下害虫蛴螬的防治效果,筛选对蛴螬高效、环保的颗粒剂。调查根埋施药后19d、31d、38d防效,进行数据分析。试验结果表明：10%丁硫克百威颗粒剂与1%联苯噻虫胺颗粒剂对蛴螬的防效较好,2%吡虫啉缓释颗粒剂对蛴螬的防效较差。10%丁硫克百威在19d后防治效果显著,1%联苯噻虫胺颗粒剂在31d后开始显著。10%丁硫克百威颗粒剂与1%联苯噻虫胺颗粒剂可以替代呋喃丹用来防治地下害虫蛴螬。

Study on Control Effect of Several Granules Underground Pest White Grub in Lawns

Four kinds of granules in treating effect on underground pest white grubs are studied, in order to select effective, efficient, environmentally friendly granule on grub. Control effect ofSrootsSafter sprayingS19d,S31d,S38d were investigated,Sand the data processed and analysed.The results show that: 10% Carbosulfan Granules and 1% Bifenthrin Clothianidin Granules has good control effect on white grubs, control effect of 2% Imidacloprid Granules on grubs is poorer. The control effect of 10% Carbosulfan Granules is remarkable after 19d, the control effect of 1% Bifenthrin Clothianidin Granules is remarkable after 31 d. 10% Carbosulfan Granules and 1% Bifenthrin Clothianidin Granules can replace the carbofuran used for prevention and control of underground pest white grub.
