玉米斑病是世界主要玉米产区普遍发生的病害,是生产上的重要问题。特别是1970年小斑病在美国大流行,引起了全世界的注意。目前国内外都认为推广抗病品种是防治玉米斑病最经济有效的措施。推广抗病品种,首先要进行抗病性鉴定。在国外,通过研究玉米抗病性和病菌致病性的化学机制,试图用化学方法测定玉米对斑病的抗病性。国
Corn streak is a common disease in the major maize producing areas in the world and is an important production issue. Especially the small spot disease in the United States in 1970 pandemic has aroused the attention of the world. At home and abroad at present, it is considered that the promotion of disease-resistant varieties is the most economical and effective measure to prevent and cure corn leaf spot. To promote disease-resistant varieties, we must first conduct disease resistance identification. Abroad, by studying the chemical mechanism of maize disease resistance and pathogenicity of the pathogen, it is attempted to determine the disease resistance of maize to spot disease by chemical method. country
