PURPOSE:To obtain a fine granular herbicide having specific particle size and improved drug activity and scattering workability, by using urea or a water-soluble inorganic salt as a solid carrier and mixing said carrier with an adjuvant and a specific herbicidal component at specific ratios thereby imparting a specific solubility to the agent. CONSTITUTION:A fine granular herbicide having a particle size of 48-150 mesh and containing 79-99wt% solid carrier, 0.5-18wt% adjuvant and 0.5-3.5wt% herbicidal component consisting of [(3-amino-3-carboxy) propyl-1]methylphosphinic acid, N-(phosphonomethyl)glycine, (2-amino-4- methylphosphino-butyryl)alanylalanine or their salt. Urea or a water-soluble inorganic salt is used as the solid carrier. The active component is adsorbed and fixed to the surface layer of the carrier in a manner that the herbicidal component and the solid carrier are wholely dissolved in water existing in the leaf and stalk of weed to exhibit sufficient herbicidal action. The herbicide has excellent storage stability and can be scattered without problem.
