Insecticidal composition and preparation method thereof

Abstract

An insecticide composition, which uses 0.1-10% of acetamiprid and 5-80% of benzalkonium bromide as the main active ingredients, and is mixed with other auxiliary agents to prepare water emulsion. The present invention has a good curative effect on various diseases such as gill rot and bleeding caused by parasites, bacterial viruses, etc. of various fish, shrimp, crab, soft-shelled turtle, eel, etc., and can effectively kill all kinds of germs harmful to aquatic organisms, Viruses and germs, viruses, harmful bacterial spores, and algae spores that mutate due to environmental deterioration; have a good killing effect on all parasites that harm fish such as trichomonas and ringworms; can also be used for fish, shrimp, crabs, etc. in the mixed culture pond. The invention has wide insecticidal and bactericidal spectrum, safe and reliable use, stable performance and convenient use.

Description

technical field

[0001] The invention relates to an insecticide composition, in particular to an insecticide composition with acetamiprid as an effective insecticide component, and the insecticide composition is mainly used in the field of aquatic biological control. The invention also relates to a preparation method of the insecticide composition. Background technique

[0002] Acetamiprid (acetamiprid) is a kind of nicotinic ultra-high-efficiency insecticide widely used in my country. Its molecule contains chloropyridyl and cyano groups, and its molecular formula is C 10 h 11 ClN 4 , molecular weight 222.7, melting point 98.9 ℃, pure product is white crystal, soluble in polar organic solvents such as methanol, ethanol, chloroform, dimethylformamide, etc., insoluble in aliphatic hydrocarbons, benzene and other solvents. Acetamiprid has the same insecticidal mechanism as the widely used imidacloprid, and is a new green and efficient insecticide variety after imidacloprid. ...
