Abstract

The invention discloses a microcapsule suspending agent preapred from carbosulfan, chlorpyrifos and abamectin by compounding, and a preparation method thereof. The microcapsule suspending agent mainly comprises 5-20% of carbosulfan, 5-20% of chlorpyrifos, 0.1-5% of abamectin, 5-15% of solvent, 2-25% of capsule wall materials, 3-8% of emulsifier, 0.1-0.4% of thickener, 3-5% of antifreezing agent, 0.01-0.5% of corrosion remover, 0.1-1% of defoamer and the balance of water. By adopting the preparation, the effective components are coated with a capsule wall to form a microcapsule of an environment-friendly and low-public hazard slow-release pesticide suspending in water by adopting an interfacial polymerization method and a coating method. The compound preparation has a broad insecticidal spectrum, has good prevention and treatment effects on soil insects such as stem borers, grubs, cutworms, root-knot nematodes, bradysia odoriphaga and the like, and over-ground insects such as phylloxera, plutella xylostella and the like on crops such as corns, peanuts, vegetables, fruit trees and the like, and is long in lasting period, and the service efficiency of the effective components of the pesticide is improved.

Description

technical field [0001] The invention relates to a new dosage form of a high-efficiency pesticide insecticidal composition, specifically a microcapsule suspension compounded with carbosulfan, chlorpyrifos and abamectin. Background technique [0002] Carbosulfan is also known as Haoniandong and carbsulfur, and its chemical name is: 2,3-dihydro-2,2-dimethylbenzofuran-7-yl(dibutylaminosulfur)methylamino Formate, its structural formula is as follows: [0003] [0004] Appearance of carbosulfan is orange to brown transparent viscous liquid, boiling point 124-128°C, vapor pressure 0.041mPa (25°C), density 1.056 (20°C), almost insoluble in water, soluble in most organic solvents, such as Xylene, hexane, chloroform, dichloromethane, methanol, ethanol, acetone, etc., hydrolyzed in aqueous solution. Carbosulfan metabolizes in insects into toxic carbofuran, which acts as an insecticide. Its insecticidal mechanism is to interfere with the nervous system of insects, inhibit cholines...
