Affected by Typhoon No. 1 of this year, the city’s heavy rain and some farmland were flooded, causing mechanical damage to rice plants. This is very beneficial to the occurrence of bacterial blight and bacterial leaf streak.

Therefore, comprehensive prevention and control of key pests and diseases of rice should be done.
