In recent years, tens of thousands of acres of wheat crop Lin Zhou Zhou wheat crops, as a result of the prevalence of wheat yellow mosaic virus disease and rampant damage, resulting in serious grain production cuts. The incidence of light reduction of 20-30%, severe cases of more than 80% reduction in production, and even some confiscated, therefore, caused enough attention to the disease, the occurrence of the rules of the experimental observation and investigation, while taking some Prevention.
