| Abstract: | Alfalfa diseases in Northeast China (Heilongjiang and Jilin Provinces)and North China (Hebei Prov-ince and the Inner Mongolia Autonomous Region)were investigated in 2013 and 2014.Fourteen alfalfa diseases were found in Northeast China,12 in Heilongjiang Province and 10 in Jilin Province,and 17 diseases were found in North China,10 in Hebei Province and 13 in Inner Mongolia.Common leaf spot,spring black stem and leaf spot,stemphylium leaf spot,downy mildew and Fusarium root rot were the five most prevalent disea-ses that would cause serious plant damage in Northeast China.The occurrence of these diseases peaked in July and August.Major differences existed in the disease varieties found at each investigation site in North China. There were five major diseases (downy mildew,rust,stemphylium leaf spot,spring black stem and leaf spot and Fusarium oxysporum root rot)which would cause serious damage in Inner Mongolia,especially when their occurrence peaked from June to September.Six diseases (common leaf spot,rust,stemphylium leaf spot,spring black stem and leaf spot,Fusarium equisetum root rot and anthracnose)were found in Langfang City and four (downy mildew,common leaf spot,rust and spring black stem and leaf spot)in Zhangjiakou City of Hebei Province.These diseases would cause serious damage,especially when their occurrence peaked from July to October for Langfang City and from June to October for Zhangjiakou City. |
