A water-dispersible herbicidol composition and use thereof, said composition having improved crystallization characteristics when dispersed in water below about 37°C at concentrations above the solubility limits of the triazine, and comprising (a) 1-methyl-3-cyclohexyl-6-dimethyl- amino-s-triazine-2,4(1H,3H)-dione, and (b) at least 2% by weight, based on the dry weight of said triazine, of a surfactant selected from isopropyl naphthalene sulfonic acid and alkali metal or alkaline earth metal salts thereof.
The defined surfactant is effective to reduce crystal growth of the triazine compound in aqueous dispersions and hence to mitigate plugging of spray nozzles thereby.
