Cyhalothrin water dispersible granule insecticide

Abstract

The invention discloses a cyhalothrin moisture particulate agent insecticide for preventing agricultural cruciferae vegetable cabbage caterpillars or aphids. The insecticide is particulate agent mix-processed by cyhalothrin, auxiliary agent and filling materials, capable of rapidly disintegrating and dispersing in water to form a high suspending and stable disperse system. The cyhalothrin moisture particulate agent insecticide belongs to insecticide for protecting plants, and is utilized for resolving the missible oil insecticide questions of low flashing, unsafe storage and transportation, bad insecticidal effect, high cost and environmental pollution. The cyhalothrin moisture particulate agent insecticide of the medicament has no floating dust during processes of producing, utilizing and packing, is safe for operators and doze not pollute environment. Compared with wettable powder, the cyhalothrin moisture particulate agent insecticide can greatly lower packing, storing and transporting cost, the medicament has great dispersity and high suspending rate in water, and cruciferae vegetable cabbage caterpillars and aphids preventing and curing rates respectively achieve 88.65-99.36% and 89.6-98.56%. Compared with the prior art, parasiticide effect of the cyhalothrin moisture particulate agent insecticide of the invention is more than one time enhanced.

Description

technical field [0001] The invention relates to an agricultural insecticide, in particular to a cyhalothrin water-dispersible granule insecticide for preventing and controlling cabbage caterpillars or aphids of cruciferous vegetables in agriculture. Background technique [0002] Cyhalothrin is also known as high-efficiency cyhalothrin Aikonin, English name: lambda-cyhalothrin Structural formula: [0003] [0004] Molecular formula: C 23 h 19 o 3 NCIF 3 [0005] Chemical name: α-cyano-3-phenoxybenzyl-3-(2-chloro-3,3,3-trichlorofluoro-1-propenyl)-2,2-dimethylcyclopropanecarboxylate 1:1 mixture of (Z)-(1R,3R),S-ester and (Z),(1S,3S),R-ester [0006] The drug is a broad-spectrum insecticide that is extremely effective against environmental sanitation pests, and has the advantages of fast knockdown speed, strong knockdown power, and less dosage. It can eliminate vector pests that spread diseases and control various sanitary pests. [0007] Cabbage caterpillar is the mo...
