Abstract

The invention relates to the technical field of pesticide preparations and specifically relates to a synergistic dinotefuran suspending agent and a preparation method thereof. The synergistic dinotefuran suspending agent is prepared from the following raw materials in percentage by mass: 35%-50% of dinotefuran, 3%-10% of wetting dispersant, 2%-5% of synergist, 0.05%-2% of thickening agent, 0-1% ofstabilizer, 2%-6% of anti-freezing agent, 0.1%-1% of defoaming agent and the balance of deionized water. The suspending agent disclosed by the invention is good in stability, strong in persistent effect, relatively low in surface tension, relatively small in contact angle, good in permeability, strong in rainwash resistance and strong in insecticidal effect.

Description

technical field [0001] The invention relates to the technical field of pesticide preparations, in particular to a dinotefuran synergistic suspension and a preparation method thereof. Background technique [0002] Dinotefuran is a third-generation neonicotinoid insecticide developed by Mitsui Chemicals. The agent has a wide insecticidal spectrum, excellent systemic penetration, and shows high insecticidal activity at a very low dose. The drug has a wide insecticidal spectrum and can prevent various pests such as Hemiptera, Lepidoptera, Diptera, Orthoptera, Hymenoptera, and Beetles. The agent is very safe to mammals, birds and aquatic organisms, and has no harm to crops. It can be used for many crops such as rice, fruit trees and vegetables. [0003] However, due to its good environmental compatibility, high drug efficacy, low cost and safe processing and use, pesticide suspension concentrates stand out among water-based formulations and have great development potential. Pe...
