Disease-resistant varieties are the most economical and effective measures for the control of rice bacterial leaf blight. Zhejiang Province in 1970 ~ 1981 is based on the wide 4, 29 green and other susceptible varieties, planting a wide area, the incidence is relatively heavy. In recent years due to the promotion of disease-resistant varieties, disease has eased. However, both the quantity and quality of disease-resistant varieties can not meet the needs of production.
