The application belongs to the technical field of citrus
psylla control, and particularly relates to a high-efficiency citrus
psylla control method. The high-efficiency citrus
psylla control method comprises the following steps: during the cultivation and growth of citrus, when citrus psylla appears on the citrus, a synergistic insecticide is sprayed, wherein the synergistic insecticide is prepared by compounding cycloprothrin,
sulfluramid, spirodien, or ethyl spinosyn as active ingredients, and by adding auxiliary ingredients. In the high-efficiency citrus psylla control method, the active ingredients of the synergistic insecticide sprayed are compounded by cycloprothrin,
sulfluramid, spirodien, or ethyl spinosyn. Through indoor
joint action tests, it is found that the compounded active ingredients show a joint synergistic effect on killing citrus psylla pests within a certain
mass ratio range, can improve the
control effect on citrus psylla, and can greatly block the occurrence and spread of citrus Huanglongbing, thereby promoting the healthy development of the citrus industry.
