How to prevent the rice stem borer (Chilo suppressalis)? Please provide an introduction to the methods
The following methods can be used for preventing the rice stem borer (Chilo suppressalis):
1. Agronomic measures. When damaged plants with dead leaf sheaths, dead hearts, or dead panicles are found, they should be pulled out promptly, which not only reduces the number of insects but also prevents larvae from moving to other plants to cause damage.
2. Chemical control. For fields that have reached the control threshold, adopt the control strategy of "spot treatment as the main approach, general treatment as supplementary, and timely treatment of young larvae." The best control effect is achieved during the peak hatching period of eggs. You can choose 5% fipronil suspension concentrate, using 40 milliliters per mu mixed with 30 kilograms of water for spraying, or apply 500 milliliters of 18% bisultap dropping granules per mu. Use pesticides 3-5 times throughout the rice growth period (with an interval of 7-10 days). Fields with severe infestations in the previous year should be treated earlier.
