description: Rice blast, also known as rice fever, fire blast, kowtow blast. Rice blast occurs in all rice producing areas in China. In epidemic years, the yield is reduced by 10-20% in general, 40-50% in severe cases, and even no grain harvest. Rice blast occurs during the whole rice growth period. According to the different stages and locations of rice damage, it can be divided into seedling blast, leaf blast, nodal blast, panicle neck blast and grain blast. Among them, panicle neck blast has the greatest impact on rice yield. [Control methods] The control strategy is based on planting high-yielding and disease-resistant varieties, reducing bacterial sources as the premise, strengthening health cultivation as the key, and chemical control as the auxiliary comprehensive measures. Cultivation of disease-resistant varieties: (1) regular rotation; (2) rational distribution; (3) application of Multi-major and micro-effective disease-resistant genes. Reduce the source of bacteria: (1) do not use germ-bearing seeds; (2) timely treatment of diseased straw; (3) seed treatment, can be 80% ethylallicin solution soaked seeds for 2-3 days or 85% strong chlorine semen soaked seeds for 0.5-1 days. Improve cultivation methods and strengthen water and fertilizer management: (1) rational fertilization, unbiased and excessive application of nitrogen fertilizer; (2) rational irrigation and drainage, water and fertilizer regulation, promotion and control combination. Pesticide control: The control of seedling blast is usually applied at 3-4 leaf stage or 5 days before transplanting; the control of panicle neck blast can be sprayed once from break to earing stage, and then the second pesticide can be applied at full heading stage according to weather conditions. Commonly used medicines are: Chunlaimycin, carbendazim, pyrimidine, cyanamide and so on.
