According to the National Agricultural Technology Extension Service Center, wheat stripe rust has recently continued to develop in Hubei, southern Henan, most of the southwest, and most of the northwestern areas. The incidence of disease in the field is relatively common, spreading from south to north into the epidemic period. As of March 2, wheat stripe rust has been seen in 290 counties in 65 cities of eight provinces in Hubei, Henan, Sichuan, Yunnan, Guizhou, Chongqing, Shaanxi and Gansu Provinces with an area of 2.551 million mu, an increase of 2.5 times year on year, 1.3 times increase over the previous week. The condition is the area with the largest area and the widest area in recent years, and the trend of spreading to the north and to the east is obvious, threatening the main wheat producing areas.
