Abstract

The invention relates to a suspension agent composition containing pyraclostrobin and a preparation method of the suspension agent composition. The suspension agent composition is prepared from the following components by weight: 1% to 30% of crude drug containing pyraclostrobin, 1% to 30% of surfactant, 0.1% to 3% of leveling agent, 0.1% to 1.0% of PH (potential of hydrogen) regulator, 0.1% to 1.0% of preservative, 1% to 20% of oily substance, and a thinner, wherein the total percent is 100 percent. The suspension agent composition has the advantage that by adopting the preparation formula, the difficult problem of poor stability in thermal storage of a pyraclostrobin suspension agent in the processing industry of pesticide preparations can be well solved.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to solving the technical problems that pyraclostrobin raw medicine is processed into a suspension product with unstable heat storage and easy crystal growth and crystal transformation of the raw medicine. Background technique [0002] The melting point of pyraclostrobin active drug is very low. At present, according to the several crystal forms disclosed, the temperature span range is relatively large, between 40 and 60°C; the physical processing properties between the various crystal forms are not complete Similarly, it is still relatively difficult to process it into a suspending agent. [0003] Easy to flocculate and coalesce. Because of the strong force between ions, flocculation and coalescence of fine particles are prone to occur, and the particles grow longer to form a larger combination, which eventually makes the suspension appear lumpy or creamy, loses flui...
