Abstract:
1. A composition for controlling vegetation comprising an aqueous suspension or slurry of thidiazuron, diuron, an emulsifier comprising alpha-butyl, omega hydroxy polyoxypropylene block copolymer with polyoxyethylene, and a dispersant comprising methyl methacrylate-methacrylic acid-monomethoxypolyethylene glycol methacrylate copolymer in an amount sufficient to maintain thidiazuron and diuron in suspension in an aqueous matrix; wherein the thidiazuron and diuron are present in a ratio of about 2:1 by weight wherein the composition has about 10 wt % to about 40 wt % thidiazuron and about 5 wt % to about 20 wt % diuron based on the total weight; wherein the alpha-butyl, omega hydroxy polyoxypropylene block copolymer with polyoxyethylene and the methyl methacrylate-methacrylic acid-monomethoxypolyethylene glycol methacrylate copolymer are each in an amount of about 2% to about 6% by weight; and wherein the composition is without added organic solvent.
