In places where the density of two-spotted stem borer egg nests is 1 nest/m2 or more, double spraying is required (first spray before flowering, second spray after flowering).
From September 21 to 23, due to the influence of the northeast monsoon, in Thai Binh province there will be moderate to heavy rain, the temperature will drop to 23 - 24 0 C. This is a favorable condition for the rice blast fungus to invade and cause damage to the green and ripening rice; two-spotted stem borer and small leaf roller due to their dense nature will cause great damage to the ripening rice area after September 20. If no preventive spray is applied, the yield will drop seriously.
The Department of Agriculture and Rural Development requests districts, cities, specialized departments, and units in the industry to strengthen direction and urge farmers to spray pesticides to prevent and control two-spotted stem borers or small leaf rollers for rice that will flower after September 20. In places where the density of two-spotted stem borer eggs is 1 nest/ m2 or more, double spraying is required (first spray before flowering, second spray after flowering). Urgently take advantage of the clear weather to spray pesticides to prevent neck blast disease on rice areas that are still green and are flowering, especially on susceptible varieties such as Q5, Thien Uu 8, local sticky rice, BC15, TBR225.
