Abstract
The water dispersible kresoxim-methyl granule is prepared from the mixture of kresoxim-methyl, an auxiliary agent and filler, and can disintegrate and disperse in water to form a high suspended stable dispersed system. The kresoxim-methyl water suspending agent is the high dispersivity stable liquid preparation prepared by mixing and processing kresoxim-methyl, the auxiliary agent and water as medium. The water dispersible kresoxim-methyl granule and the kresoxim-methyl suspending preparation have no float fly ash in the production, using and packaging processes, safety for operators, no pollution of the environment, comparability with wettable powder, large density, small volume, greatly reduced cost of package, storage and transportation, convenient recovery of the package, good dispersivity in water, high suspension percentage and enhanced control efficiency.
Description
One, technical field
The present invention relates to a kind of novel formulation of disinfectant use in agriculture, specifically two of the bactericide kresoxim-methyl kinds of preparations, i.e. kresoxim-methyl water dispersible granules (WDG) and kresoxim-methyl aqueous suspension agent (SC).
Two, background technology
Kresoxim-methyl (Kresoxim-methyl) has another name called kresoxim-methyl, belongs to methoxy acrylic bactericide.
Structural formula:
Chemical name is:
(E)-α-methoxy imino-2-[(2-methylphenoxy)-methyl] methyl phenylacetate.Be mainly used in wheat, corn, jowar, paddy rice, fruit tree, vegetables, potatoes and other crops, most of diseases that pathomycetes such as Ascomycetes, Basidiomycetes, Fungi Imperfecti and oomycetes subclass are caused have treatment, protection and eradicant action.It is quite valued both at home and abroad in recent years new outstanding kind.CN1237088A discloses the method for this compound control fungi, but does not point out formulation.The disclosed microbicide compositions of CN1359620A is the complex preparation of this compound and other bactericide.The preparation of current kresoxim-methyl is based on wetting powder, and kind is single, and is producing, packing dust drift in the use, and contaminated environment directly endangers the operator, and bactericidal effect is poor simultaneously.
Three, summary of the invention
Water dispersible granules (Water dispersible granule, WDG or WG) disintegration soon, dispersion in water, the dispersion of form higher suspension.It comprises components such as active component, wetability, dispersant, disintegrant, stabilizing agent, burl agent and filler.
Aqueous suspension agent (Suspension concentrate or SC) is to be dispersion medium with water, the formulations of pesticide that former medicine, auxiliary agent (wetting agent, dispersant, thickener, stabilizing agent, antifreezing agent and defoamer) are made through waterproof pulverization.It has polymolecularity and stability.
Task of the present invention is processed into kresoxim-methyl water dispersible granules (calling kresoxim-methyl WDG in the following text) and aqueous suspension agent (calling kresoxim-methyl SC in the following text) exactly.
