蚕豆主要病虫害全程生物农药防控技术研究

Field trials of biopesticides for whole course management of broad bean diseases and pests

目的:研究蚕豆生育期主要病虫害全程生物农药防控技术.方法:从播种期开始选择枯草芽孢杆菌、哈茨木霉、多粘类芽孢杆菌、藜芦碱、蛇床子素、植物免疫蛋白和微量元素水溶性肥料对蚕豆田主要蚜虫、赤斑病、枯萎病进行全程生物农药防治.结果:全程生物农药防控对蚜虫、赤斑病、枯萎病的防效均在70%以上,且较常规化学防治技术增产达到12.86%,品质得到提升,商品优良率提高10%,可进一步大面积示范推广.

Objective:In order to study the whole-process biological pesticide control technology of main diseases and insect pests of broad bean.Method:the whole-process biological pesticide control was carried out on the aphids,red spot and blight of broad bean field.From the sowing time,select Bacillus subtilis,Trichoderma harzii,Bacillus polymyxoid,veratrol,osthol,plant immune protein and water soluble fertilizer with trace elements.Conclusion:The results showed that the control effect of biological pesticide on aphids,red spot and fusarium wilt in the whole process was more than 70%.Compared with the conventional chemical control technology,the yield increased by 14.8%,the quality was improved,and the rate of good and good products increased by 12%,which could be further demonstrated and popularized in a large area.
