Abstract

The invention discloses an insecticidal composition. The insecticidal composition comprises the active ingredients of benfuracarb insecticide and neonicotinoid insecticides comprising any one of thiamethoxam, clothianidin, acetamiprid, imidacloprid and nitenpyram; and the active ingredients can be prepared into wettable powder, granules, water dispersible granules, suspending agents, soluble liquid and suspension seed-dressing seed coating agents. The weight ratio of the active agents comprising the benfuracarb insecticide and neonicotinoid insecticides chosen from any one of thiamethoxam, clothianidin, acetamiprid, imidacloprid and nitenpyram is (1-100):(1-10); the total weight percentage content of the active ingredients is 0.2 to 68 percent; and other ingredients are auxiliary ingredients which are allowable in pesticides. The insecticidal composition has the advantages that: obvious synergism is achieved, using amount of the pesticides is reduced, action range is enlarged, medicine resistance is avoided or medicine resistance is delayed and the like.

Description

technical field [0001] The invention relates to an insecticidal composition containing carbosulfan and neonicotinoid insecticides. Background technique [0002] Carbosulfan, also known as prothiocarb, English common name: benfuracarb, the product is a brown-red viscous liquid, slightly soluble in water (8mg / L), easily soluble in most organic solvents, LD 50 138mg / kg. Carbofuran is a highly efficient and low-toxic derivative product obtained in the development and research of the carbamate insecticide "precursor pesticide" carbofuran in the early 1980s. It is an inhibitor of cholinesterase. It has contact killing, stomach poisoning and systemic effects, and has a long lasting effect. It mainly controls various pests with sucking mouthparts and chewing mouthparts in rice, cotton, corn, soybean, vegetables and fruit trees. Compared with the precursor carbofuran, the toxicity of the new low-toxic derivatives is reduced by 20 to 50 times, the insecticidal activity is not greatl...
