Abstract

The invention discloses a pyraclostrobin aqueous suspension agent and a preparation method of the pyraclostrobin aqueous suspension agent. The pyraclostrobin aqueous suspension agent comprises the following ingredients in percentage by weight: 1 to 50 percent of pyraclostrobin, 1 to 8 percent of dispersing agents, 1 to 10 percent of wetting agents, 0.1 to 2 percent of thickening stabilizers, 1 to 10 percent of antifreezing agents, 0.1 to 1 percent of defoaming agents, 0.1 to 0.5 percent of preservatives and the balance of de-ionized water. Except the thickening stabilizers, the materials are subjected to stirring and sand grinding, then, the thickening stabilizers are added, the stirring is carried out, and in addition, a proper number of pH regulating agents are added. The pyraclostrobin aqueous suspension agent and the preparation method have the advantages that the flashing point is high, non-flammable and non-explosive performance is realized, the production, the storage and the use are safe, the environment pollution is low, the product cost is low, the package is easy, and the like.

Description

technical field [0001] The invention relates to a pesticide preparation and a preparation method thereof, in particular to an aqueous suspension of pyraclostrobin and a preparation method thereof. Background technique [0002] Chemical control is an important means for humans to prevent and control agricultural and forestry diseases and insect pests. Chemical pesticides play a very important role in increasing agricultural production and income. and social issues. Therefore, the development direction of the pesticide preparation industry is to gradually develop towards safety, environmental protection and water-based. Pesticide suspension concentrate refers to a preparation that uniformly disperses solid pesticide original medicine in water with particles below 4 microns. It is an environmentally friendly product that is non-flammable and explosive, has small particle size, high biological activity, large specific gravity, and small packaging volume. Pesticide formulations...
