Abstract

The present invention belongs to the technical field of compound pesticides, and particularly relates to a wheat mite control emulsion in water. The effective ingredients of the composition are theta-cypermethrin and triazophos, the weight ratio of triazophos to theta-cypermethrin is 5:1 to 1:5, the compound composition can effectively inhibit the problem of production of resistance of pests, and maximally alleviates the problem of the drug resistance of the pests in the prior art, thereby reducing the dosage of the pesticide, and alleviating the impact on the environment, and the compound composition is in line with the social trend of green and environmental protection, and the composition reaches the best effect of crop protection.

Description

technical field [0001] The invention belongs to the technical field of compounding of pesticides and insecticides, in particular to an emulsion in water capable of preventing and controlling wheat spiders. Background technique [0002] Triazophos [0003] Chemical name: O,O-diethyl-O-(1-phenyl-l,2,4-triazol-3-yl)phosphorothioate [0004] Molecular formula: C12H16N3O3PS Molecular weight: 313.3125CAS no: 24017-47-8 [0005] Physical and chemical properties: The pure product is a light brown liquid with a melting point of 0-5°C and a specific gravity of 1.247. At 30°C, its vapor pressure is 0.387mPa. At 20°C, its solubility in water is 35mg / L; it is soluble in most organic solvents. Stable to light, hydrolyzed in acid and alkali medium, decomposed at 140℃. [0006] It is a moderately poisonous, broad-spectrum organophosphorus insecticide with strong contact and stomach toxicity, good insecticidal effect, obvious ovicidal effect, strong permeability, and no systemic effect. ...
