Compound pesticide composition containing spirotetramat and application thereof

Abstract

The invention discloses a compound pesticide composition containing spirotetramat and an application thereof, and belongs to the field of chemical prevention and control of injurious insects. The composition is an insecticide composition which comprises amitraz used as a first active constituent and spirotetramat used as a second active constituent, wherein the mass ratio of the amitraz to the spirotetramat is (1-20):(1-20). Cotoxicity coefficients of the compound pesticide composition to diaphorina citri are all bigger than 120, and the constituents of the compound pesticide have good synthetic interactions. The compound pesticide composition is used for preventing and controlling the diaphorina citri, is reasonable in matching ratio of each constituent, and has obvious synergism in activity and insecticidal efficacy, meanwhile, the compound pesticide with the matching ratio has good preventing and controlling effects on panonychus citri, can delay generation of drug resistance, and guarantees good safety for crops.

Description

technical field [0001] The invention belongs to the technical field of pest chemical control, in particular to an insecticide compound composition with a synergistic effect on citrus psyllids. [0002] technical background [0003] Citrus is one of the world's most important economic crops and international agricultural products and processed products, and is the largest fruit in international trade. In recent years, the occurrence of citrus greening disease has seriously threatened the development of citrus industry. The disease can cause mottled yellowing on the leaves of the host, the symptoms of "red nose fruit" on the fruit and the weakening of the tree vigor of the whole plant. The young trees usually die within 2-3 years after the onset, and the adult trees generally die within 5-8 years after the onset , has seriously affected the economic value of citrus. The disease can infect all citrus varieties, and there is no effective treatment for the disease at present. On...
