不同药剂对蚕豆赤斑病综合防控效果分析及综合防控体系研究

摘要

Chocolate Spot is one of most serious diseases in broad bean farming in our country, and it is becoming much more threatening with the climate change in recent years.With the support of National Legumes System,we did some research work on it from 201 1 to 2013 and in 8 different farming districts.After the experiments we found that Mancozeb wp,the best in all chemical fungicides,can prevent above 80% of the disease and increase more than 1 6% of the total yield while reduction bacteria,the best in all biological fungicides,can prevent 40% of the disease and increase 8% of the total yield.The experiment also built a prevention and con-trol system ranging from the germplasm selection,building of the warning system to the fun-gicides using,etc.%赤斑病是我国蚕豆上最重要的要病害之一，近几年由于气候变化反常，该病在一些地区发展尤为严重。在国家食用豆产业技术体系的支持下，于2011—2013年对国内8个不同产区蚕豆赤斑病进行药剂筛选试验，化学药剂中80%代森锰锌可湿性粉剂对赤斑病田间综合防效达到80%以上，对蚕豆产量也比对照增产16%以上；生防药剂中裁菌平均防效达到40%以上，蚕豆产量也比对照增产8%左右，起到了较好的防治效果。此外，还建立了包括资源筛选、早期预警机制建立、药剂防治等综合防治手段的立体防控体系。
