Many types of pests and diseases arise in spring rice.

This spring crop, Thai Nguyen has planted over 28 thousand hectares of rice, with high-quality hybrid and purebred rice varieties. Currently, the rice plants are in the stage of intensive tillering, standing, and panicle formation, and some rice areas have begun to flower. The weather in the past few days has been hot and sunny, with intermittent rain, which is very favorable for some pests and diseases to arise and cause damage to spring rice.

Adult stem borers have appeared and bloomed, with a high risk of causing silver leaf on rice in early May and panicle rot on rice in mid-May.

Leaf blast disease has an average damage rate of 1-10%, in high places 20-30%, locally 50% (in Dong Hy, Dinh Hoa, Phu Luong, Phu Binh...) on varieties J02, sticky rice, TBR 225...
