Abstract

The invention relates to a composition of chitin and avermectin or emamectin benzoate for insecticide and acaricide, and is characterized in that the dosage form of the compound preparation is microemulsion and the weight percentage of effective components in the compound preparation contains 0.5 to 10 percent of the chitin, 0.2 to 2 percent of the avermectin or 0.2 to 1.5 percent of the emamectin benzoate, with the rest of an auxiliary agent, a cosolvent and water. The pesticide preparation of the invention has no public pollution and can be applied to prevention of pests and mites in agricultural production, in particular to the prevention of plant nematode diseases.

Description

technical field [0001] The invention relates to a new agricultural insecticidal and acaricidal preparation, in particular to an insecticidal and acaricidal microemulsion composed of chitin, avermectin or emamectin benzoate. Background technique [0002] Chitin, also known as chitin, polyacetylglucosamine, etc., is white translucent flake solid in appearance, insoluble in water, dilute acid and dilute alkali. After deacetylation, chitin becomes deacetylated chitin, also known as chitosan (Chitosan), insoluble in water and dilute alkali solution, but soluble in most dilute acids, also known as soluble chitin; chitin or chitosan after Some reactions can be easily soluble in water chitin, also known as water-soluble chitin. [0003] At present, the chitin used in agriculture mainly includes soluble chitin and water-soluble chitin. The shell has better physiological activity in controlling nematodes. Water-soluble chitin does not need to add organic or inorganic acids to prepa...
