小麦条锈病是长期障碍我省中部、西部和西北部小麦生产发展的一种主要病害。轻病年份发病面积近一百万亩,约占小麦播种总面积的13%,重病年份如1981年竟高达270万亩,占40%,减产一亿五千万斤。长期以来,由于对病原菌的越夏规律不清,未能从抗锈良种的合理布局方面控制此病的危害,因而到七十年代,先后出现了1973、1979年的大流行。我院植保所自1979年夏季分别在重病地区的安宁、丽江等县对小麦条锈病菌的越夏情况进行了探索性调查,在自生麦和夏麦上均发现了条锈病发生。同一情况在1980年的调查中又得以印证,因而初步认为小麦条锈病菌可以在我省
Wheat stripe rust is a long-term obstacle to the development of wheat in central, western and northwestern provinces as a major disease. Slightly ill year incidence area of nearly one million mu, accounting for about 13% of the total area planted with wheat, seriously ill year as 1981 up to 270 million mu, accounting for 40%, cut 150 million kilograms. For a long time, due to the unclear summer rules of pathogenic bacteria and the failure to control the harm of the disease from the rational layout of anti-rust seeds, the seventies saw the occurrence of the 1973 and 1979 pandemics successively. The Institute of Plant Protection of our hospital in the summer of 1979, respectively, in the areas of peace, Lijiang and other counties of wheat stripe rust pathogen over the exploratory survey conducted in both self-malting and summer wheat were found stripe rust. The same situation was confirmed in the survey in 1980, which initially suggested that wheat stripe rust can be found in our province
