According to statistics from the People's Committee of Thanh Chuong district,To date, 473 hectares of rice in the area have been infected with rice blast disease, of which 20 hectares have a severe infection rate, posing a risk to yield and production if not controlled promptly.

Rice varieties severely affected by the disease include: Huong Uu 98, Thai Xuyen 111, and Thien Uu 8. The most severely affected communes are Thanh Yen, Thanh Khai, Thanh Luong, Thanh Tung, Thanh Khe, and Thanh Thinh… Mr. Nguyen Nhu Quan, Deputy Head of the District Plant Protection Station, said: Upon detecting the disease, the department advised farmers to spray specific pesticides according to the "four correct principles." If the first spraying is followed by rain, a second spraying should be done after 5-7 days. During the period when the rice is diseased, nitrogen fertilization should be stopped immediately…

Currently, the rice plants are in the tillering and heading stage. Leaf blast disease is temporarily under control, but the risk of neck blast is also becoming a concern.
