Bt WDG稳定性与防治小菜蛾试验
Application of Bacillus thuringiensis Water Dispersible Granule
【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。
【Abstract】 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.
