<p>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.</p> |
