Abstract

The invention discloses a phosethy-Al and folpet water dispersible granule and a preparation method thereof. The effective components of the phosethy-Al and folpet water dispersible granule are phosethy-Al and folpet, and the water dispersible granule is prepared by mixing phosethy-Al and original folpet with wetting agents, dispersants, disintegrants, thinners and adhesives, wherein the content of the phosethy-Al is 20 to 60 percentage by weight, and the content of the folpet is 10 to 50 percentage by weight. The preparation method comprises the following steps of: stirring the components well and grinding the mixture to obtain original powder, adding a certain proportion of deionized water to the original powder and uniformly mixing, and then granulating, drying and sieving to obtain the phosethy-Al and folpet water dispersible granule. When the phosethy-Al and folpet water dispersible granule is used, the cost is lowered, and environmental pollution is reduced. Compared with the single dose, because the compound technique is adopted, the efficacy is improved, and the toxicity is lowered. Because different addition agents are added, the water dispersible granule has the advantages of high active component content, high disintegration speed, good dispersive property, good heat storage performance, high bactericidal potence, high safety, and the like.

Description

technical field [0001] The invention relates to two kinds of agricultural fungicides, in particular to a kind of aluminum triethylphosphate · fendan water dispersible granule and its preparation method. Background technique [0002] At present, there are many agricultural fungicides, aluminum triethylphosphate and folpet are two of them. Aluminum triethylphosphate is a systemic fungicide, which can be absorbed by plant leaves, stems, roots, and seeds into the plant body, and can be transported, diffused, retained or produced metabolites through plant body fluids, which can prevent and control some fungicides that penetrate into the plant body or Diseases in the endosperm of seeds to protect crops from infestation by pathogens or to treat infected plants, so they have therapeutic and protective effects. Aluminum triethylphosphate has the control effect on eggs and fungi, and is suitable for diseases caused by various fungi. It can prevent and control tomato late blight, ring...
