In areas where the density of two-spotted stem borer egg clusters is 1 cluster/m2 or more, double spraying is required (first spraying before flowering, second spraying after flowering).

From September 21-23, due to the influence of the northeast monsoon, moderate to heavy rain fell in Thai Binh province, and the temperature dropped to 23-24 ^° C. This created favorable conditions for rice blast disease to invade and damage rice crops that were still green and heading; the two-spotted stem borer and small leaf roller, due to their high density, have a very high potential for causing damage to rice crops that headed after September 20. If pesticides are not sprayed, yields will be severely reduced.

The Department of Agriculture and Rural Development requests that districts, cities, specialized departments, and units within the sector strengthen guidance and supervision of farmers to spray pesticides to control two-spotted stem borer or small leaf roller on rice crops that have flowered after September 20th. Where the density of two-spotted stem borer egg clusters is 1 cluster/ ^m² or more, double spraying is required (first spraying before flowering, second spraying after flowering). Farmers should also take advantage of dry weather to spray pesticides to prevent rice blast disease on rice crops that are still green and flowering, especially on susceptible varieties such as Q5, Thien Uu 8, local glutinous rice, BC15, and TBR225.
