HERBICIDAL AQUEOUS DISPERSION FORMULATION, MANUFACTURING METHOD THEREFOR AND METHOD FOR REDUCING CHEMICAL INJURY BY THE FORMULATION

摘要

PROBLEM TO BE SOLVED: To provide a herbicidal aqueous dispersion formulation capable of reducing chemical injury while reducing effects on environment by providing physical effects on chemical injury component, a manufacturing method therefor and a method for reducing chemical injury by the formulation.;SOLUTION: The formulation contains a herbicidal activity component, a porous powder, at least one kind of dispersion stabilizer selected from a group consisting of a surfactant and a protective colloid agent and water and the content of the porous powder is 1 to 40 pts.wt. based on 100 pts.wt. of the formulation. A method for reducing chemical injury by the formulation includes spraying the formulation obtained by mixing the herbicidal activity component, at least one kind of dispersion stabilizer selected from the group consisting of the surfactant and the protective colloid agent, water and the porous powder of 1 to 40 pts.wt. based on 100 pts.wt. of the formulation to rice paddy under flooding. This inhibits absorption of the chemical injury component of the formulation to rice body leaf sheath, prevents the chemical injury component maintained in the porous powder contacting with lead and stem and the chemical injury reduction effect is achieved, as shown in Fig. 1.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2017,JPO&INPIT
