Dispersible herbicidal compositions and methods of use
Herbicidal dispersible concentrates include an herbicide and substantially water miscible amide-based solvents. Such concentrates may be diluted in water and used in methods to control weeds.
1. A method of treating weeds comprising applying to the weeds an herbicidally effective amount of a formulation comprising:
an agrochemical dispersible concentrate and water, the dispersible concentrate comprising:
about 10% to about 20% by weight of the concentrate of topramezone; and
about 0.6% to about 90% by weight of the concentrate of N-methyl pyrrolidone;
wherein topramezone is the only active ingredient of the dispersible concentrate;
wherein in a ratio of dispersible concentrate to water is in a range from about 1:50 to 1:25,000 by volume, and wherein the formulation is in the form of a colloidal suspension.
2. The method of claim 1 , wherein the weeds are monocots or dicots.
3. The method of claim 1 , wherein the weeds are resistant to glyphosate, acetolactate synthase inhibitors, protoporphorin oxidase IX inhibitors, or triazine inhibitors.
4. The method of claim 1 , wherein the formulation further comprises an additive selected from the group consisting of a surfactant, urea-ammonium nitrate (UAN), and combinations thereof.
