How to control stem borer in rice (tana chhedak)?

Control rice stem borer by monitoring for dead hearts in the vegetative stage and white ears at panicle stage, and clip and destroy egg masses early. Use pheromone traps to track moth flights and install them in the field. Cartap hydrochloride or chlorantraniliprole granules or sprays at the recommended dose give good control when applied at egg hatching or early infestation. Avoid excess nitrogen, remove stubble that harbours larvae, and conserve egg parasitoids like Trichogramma, which can be released as cards. Synchronised planting in a village reduces carryover. Confirm product and dose with your local KVK as recommendations change.
