摘　　要：龙胆草斑枯病是龙胆草生长过程中最严重的病害,主要危害叶片。近几年,龙胆草种植面积大为减少,斑枯病防治技术研究少有报道。据调查,采用常规药剂不能有效防治,造成龙胆草斑枯病发病率达到80%以上,有时甚至达到100%。为避免此病造成严重损失,我们开展了龙胆草斑枯病防治药剂筛选研究。试验结果表明,凯润、凯泽对龙胆草斑枯病具有较好防治效果,可有效防止龙胆草斑枯病的发展。Gentia leaf blight is the most seriously diseases during the process of man-made cultivating,and mainly harms the leaf. In recent years , the area of man-made cultivating is reduced seriously, and it has few reports of this disease＇s control technique. According to investigates, it can not control the disease effectively with common reagents, so the incidence rate of gentia leaf blight reaches as high as 75%, and the highest rate can be up to 100%. So as to reduce the loss, we bigen this study of safe and highly effective reagents. The results showed that the Kairun and Kaize can control the gentia leaf blight effectively ,and suppress the development of this disease.
