Rice temperature disease is one of the most serious diseases that damage rice. It belongs to the world's rice diseases. The reduction in production is generally 10-15%. Severe land masses can lead to outbreaks, so it is crucial to do preventive work.
Rice blast generally begins to occur in early July in the province. The period of damage is from late July to mid-August. During this period, in case of unfavorable climatic conditions such as high temperature (optimal 25-28°C), high humidity (relative temperature 90% or more), and widows, we must promptly prevent it. The main measures include: 1. Conduct field inspections carefully and find that the disease center does not spray drugs for control. 2, fertilization should be based at the end of the main fertilizer to see seedlings (by its use to control the use of nitrogen fertilizer). The water layer is mainly shallow irrigation to enhance the resistance to disease. 3. The disease area is expanded, and Fujitsu No. 1 and Keweisan are used for prevention and treatment.
