To effectively prevent and stop the spread of rice blast disease, the Department of Agriculture and Rural Development requests the People's Committees of districts, towns and cities to direct specialized agencies to strengthen field inspections, guide farmers on technical measures to care for and prevent rice blast disease; urge the People's Committees of communes, wards and towns to urgently direct cooperatives and farmers to implement technical measures according to the instructions of specialized agencies.

Increase inspection and spray pesticides promptly when the disease rate is about 5%. Severely damaged areas must be sprayed a second time 5-7 days after the first time.

At the same time, increase the water level and stop fertilizing all types of fertilizer until the disease stops developing. Spray neck blast prevention medicine 5-7 days before rice blooms, especially in areas infected with leaf blast, epidemic areas, fields with excess nitrogen fertilizer, and areas where infected seeds are sown.
