Silkworm toxin insecticides have strong contact and stomach toxicity effects. They invade the binding sites of nerve cells, blocking the transmission of acetylcholine secreted by the previous nerve cell to the subsequent nerve cell, thus preventing the nerve cells from becoming excited. This causes the insect's nerves to become paralyzed, unable to gnawing, move, and stop developing, eventually leading to death. It has a good control effect on both the rice stem borer and the rice stem borer, and can also control the rice leaf roller, leafhoppers, slime beetles, etc. It is also effective against the small vegetable moth and the yellow-striped spiny beetle. For the rice stem borer and rice stem borer, spray with 50% soluble powder at a dilution of 1000 to 1500 times. For the rice bud worm and rice leaf rolling worm, spray with 1000 times dilution. For the water stem borer, water stem ash borer, small vegetable moth, yellow striped flea moth, citrus leaf miner, and onion thistle, spray with 1000 times dilution.
