Qingshui spring temperatures picked up faster, precipitation increased month by month. The temperature rose to 2-3 ° C in early March, rose above 10 ° C in mid-April and averaged 119 millimeters from March to May. Therefore, the climatic conditions in spring wheat stripe rust disease occurrence and development is appropriate. To test my county wheat stripe rust overwintering summer problem, for the control of the prevalence of wheat stripe rust in our county, control and control of stripe rust, the development of wheat production, with practical significance. First, the winter wheat stripe rust first, to test the wheat stripe rust base before winter. The incidence of wheat autumn seedlings in our county concentrated in October, the monthly average of the calendar year
