Abstract

The invention belongs to the technical field of pesticides and particularly relates to a suspending agent and a preparation method thereof. The suspending agent contains the following components in percentage by mass (100% in total): 0.5%-10% of emamectin benzoate, 2%-15% of a solubilizer, 1%-3% of a wetting agent, 2%-4% of a dispersing agent, 0.5%-2% of an antioxidant, 2%-5% of an anti-freezing agent, 1%-5% of a film forming agent, 1%-10% of a coloring agent, 0.1%-3% of a thickening agent, 0.2%-0.4% of a defoaming agent, 0.1%-0.5% of a preservative and the balance of water. By virtue of a synergistic effect of the components and the contents, emamectin benzoate can stably exert the pesticide effects, so that the use cost is lowered; and the suspending agent does not contain organic solvent, so that the suspending agent is safe in the production and use processes and is environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a suspending agent and a preparation method thereof. Background technique [0002] In modern agricultural production, chemical treatment of seeds with seed treatment agents is one of the most economical and convenient methods to prevent and control underground pests and crop soil-borne and seed-borne diseases. Seed treatment suspension concentrate is a pesticide formulation with film-forming properties for the treatment of crop or other plant seeds. The seed treatment suspension can solidify on the surface of the seed to form a film called a seed coat, absorb water and swell in the soil without being dissolved, allow the water and air required for normal germination of the seed to pass through, and slowly release the pesticides and seed fertilizers contained in it , can kill underground pests and seedling pests, prevent and control seedling diseases and systemic d...
