Agricultural chemistry is the study of both chemistry and biochemistry which are important in agricultural production, the processing of raw products into foods and beverages, and in environmental monitoring and remediation. These studies emphasize the relationships between plants, animals and bacteria and their environment. The science of chemical compositions and changes involved in the production, protection, and use of crops and livestock. As a basic science, it embraces, in addition to test-tube chemistry, all the life processes through which humans obtain food and fiber for themselves and feed for their animals. As an applied science or technology, it is directed toward control of those processes to increase yields, improve quality, and reduce costs. One important branch of it, chemurgy, is concerned chiefly with utilization of agricultural products as chemical raw materials. Etc.

Water-dispersible granule containing paraquat dichloride and its preparing method
InactiveCN1376030AAvoid poisoning hazardsEfficient removalBiocideDead animal preservationSodium BentonitePyrophyllite
The present invention relates to a water dispersible granule containing Paraquat Dichloride and preparation method thereof. The paraquat, an active component of a nonselective herbicide, is generally known to be inactive due to its strong adsorption to minerals in the soil, particularly to extender such as clay, bentonite, talc, pyrophyllite, montmorillonite, etc. Paraquat is transformed into the water dispersible granule type, so that the dispersible granule type can have safety to human body and superior agrichemical effect than other formulation types such as soluble concentrate type or wettable powder type. The agrichemical composition according to the present invention is prepared by mixing and kneading 5-50 wt.% of paraquat, 5-30 wt.% of surfactant, 1-2 wt.% of disintergrant and the rest of carrier, forming granules out of kneaded mixture, and drying the granules.
