摘　　要：对苏云金杆菌水分散颗粒剂(Bt WDG)的稳定性、防治效果、技术指标等的研究结果表明,水分散颗粒剂的平均降解率为15.1%,优于可湿性粉剂的19.8%;小区试验,水分散颗粒剂与可湿性粉剂在同样剂量下防效相当;大田示范,水分散颗粒剂防效略优于对照药剂;各项技术指标均达到水分散颗粒剂企业标准的要求。The stability and application effect and technical indexs Bacillus thuringiensis （Bt）water dispersible granule （ WDG ）. Was studied in the paper. Results showed that average decompose rate of Bt WDG was 15.1%, better than Bt WP. Field testing showed that the effect of Bt WDG was closed to comparison pesticides. Other indexs could reach the quality standard of WDG.
