Problems solved by technology

Its disadvantage is mainly that it is highly toxic to fish, and it is also harmful to some beneficial insects. Long-term repeated use will also lead to resistance of pests
[0004] However, in the actual process of agricultural production, the most likely problem in pest control is the generation of pest resistance

Abstract

The invention discloses an insecticidal composition comprising spirotetramat and pyrethroid. The composition is mainly characterized in comprising an active component A, an active component B, and balance of auxiliary agents. The active component A is spirotetramat, and the active component B is any one of permethrin, lambda-cyhalothrin, fenvalerate, beta-cyfluthrin, deltamethrin, and fenpropathrin. A weight ratio of the active component A to the active component B is 60:1-1:60. The composition can be prepared into wettable powders, water-dispersible granules, suspensions, suspension emulsions, water emulsions, micro-emulsions, microcapsule suspensions, and microcapsule-microcapsule suspensions. The composition provided by the invention can control various pests, and has substantial synergetic effect and sustained-release effect. The composition is safe to human and animals, and has the advantages of no phytotoxicity and good environmental compatibility. The preparation has the advantages of enhanced adhesion, rain erosion resistance, long duration, and the like.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to an insecticidal composition containing spirotetramat and pyrethroids. Background technique [0002] Spirotetramat (spirotetramat), molecular formula: C 21 h 27 NO 5 , chemical name: 4-(ethoxycarbonyloxy)-8-methoxy-3-(2,5-xylyl)-1-azaspiro[4,5]-dec-3-ene- 2-keto is a new type of tetronic acid insecticide with a broad insecticidal spectrum and long-lasting effect. It works by interfering with lipid biosynthesis in insects leading to larval death and reduced adult reproductive capacity. Due to its unique mechanism of action, it can effectively control pests resistant to existing insecticides, and at the same time, it can be used as an important species for the management of neonicotinoid insecticide resistance. [0003] Pyrethroids are a class of broad-spectrum insecticides that can control a variety of pests, and their insecticidal toxicity is 10-100 times higher than that of ...
