不同杀菌剂对毛豆豆荚炭疽病的防治效果研究

Study on the Control Effect of Different Fungicides to Beanpod Anthracnose of Green Soybean

选用68.78%易保水分散粒剂、10%世高水分散粒剂等4种杀菌剂进行毛豆豆荚炭疽病的大田药剂试验。结果表明,68.78%易保水分散粒剂稀释1000倍的处理防治效果最好,该药对毛豆豆荚炭疽病的防效显著而且持久,在药后7d和14d时,相对防效均可达75%以上,优于其他杀菌剂。

Four kinds of pesticides （including 68.78% Yibao WDG, 10% Shigao WDG, etc.） are chosen for the field drug experiment about the beanpod anthracnose of green soybean. The result shows that the 68.78% Yibao WDG diluted with 1000 times water has remarkable and lasting effect, and the relative control effect which is all in excess of 75% after medicine of 7d and 14d is superior to the other fungicides.
