Water suspension agricultural chemical formulation and suspension stabilization medicine

摘要

PROBLEM TO BE SOLVED: To provide an aqueous suspended agricultural chemical preparation without separating or sedimenting during storage for a long period of time by adding a specific suspending stabilizer to a herbicide active component and further adding a specific polymeric compound, a surfactant and water, and adjusting viscosity of the preparation within a specified range. ;SOLUTION: This aqueous suspended agricultural chemical preparation is composed of a herbicide active component, a suspending stabilizer comprising an isopropylnaphthalene-based solvent of the formula {(m) is 0-2; (n) is 1-2}, a natural water-soluble polymeric compound, a surfactant and water, and viscosity of the preparation is adjusted to 100-1,000mPa.s at 25°C. A content of the herbicide active component in the aqueous suspended agricultural chemical preparation is 0.1-60wt.%. As the compound of the formula, e.g., monomethylmonoisopropylnaphthalene is exemplified and its adding amount is about 0.02-50 pts.wt. based on 1 pt.wt. of the agricultural chemicals active component. As the natural water-soluble polymeric compound, e.g., starch, carrageenan, pectin and pullulan and its adding amount is about 0.01-10wt.%. The adding amount of the surfactant is about 0.2-30wt.%.;COPYRIGHT: (C)1997,JPO
