Agricultural chemical composition

Abstract

The invention relates to a pesticide composition, in particular to a pesticide composition comprising avermectin with the synergistic effective quantity and methylamino abamectin benzoate, wherein the preferred weight ratio of the avermectin to the methylamino abamectin benzoate is between 20 to 1 and 1 to 10, the more preferred weight ratio is between 10 to 1 and 1 to 5, and the most preferred weight ratio is between 2 to 1 and 1 to 2. The pesticide composition is particularly suitable for preventing and controlling pests and pest mites such as prodenia litura.

Description

technical field

[0001] The invention relates to a synergistic pesticide composition, in particular to a synergistic pesticide composition comprising abamectin and emamectin benzoate. Background technique

[0002] Abamectin (abamectin) is a macrolide disaccharide compound, a natural product isolated from soil microorganisms, which has contact and stomach toxicity to insects and mites and has a weak fumigation effect without systemic absorption. effect. Abamectin has a strong penetrating effect on the leaves, can kill the pests under the epidermis, and has a long residual effect, but it is ineffective for the eggs of most insects. Its mechanism of action is different from that of general insecticides in that abamectin interferes with neurophysiological activities and stimulates the release of r-aminobutyric acid, while r-aminobutyric acid can inhibit the nerve conduction of arthropods, and mite adults, nymphs and Insect larvae will appear paralyzed after contact with the dru...
