According to the Measures for the Administration of Pesticide Registration issued by the Ministry of Agriculture and Rural Affairs, abamectin and deltamethrin are both effective pesticides, which can be used to control rice borers. Avermectin is a highly effective and low toxic pesticide, which has a good control effect on rice stem borers. Deltamethrin is a broad-spectrum insecticide, which has a good killing effect on many pests. Therefore, abamectin plus deltamethrin can effectively control rice stem borers.
