  • Method and composition for treating and promoting the growth of plants
    Patent number: 6589916
    Abstract: Described is a method for promoting the growth of plants in general and promoting the growth and enhancing the color of grass in particular. The method treats the plants and the soil in which they grow with a fungicidally effective amount of methylammonium methyldithiocarbamate, the fungicidally effective amount being insufficient to significantly retard the growth of the grass. In the practice of the invention, the plants are treated with an aqueous solution of methylammonium methyldithiocarbamate by dripping or spraying the solution onto the plants, by injecting the aqueous solution into the soil, or by drenching the soil with the aqueous solution. Significantly reduced amounts of methylammonium methyldithiocarbamate are employed to reduce damage to the plants.
