Abstract
Compositions and methods for controlling, mitigating, or reducing undesired vegetation including difficult to control weed species such as Juniper and Kochia. Methods for controlling, mitigating, or reducing undesired vegetation belonging to one or more difficult to control weed species may include applying to the undesired vegetation or its environment an herbicidally effective amount of an oil dispersion formulation, the oil dispersion formulation comprising aminocyclopyrachlor in a free-acid form suspended or dispersed in one or more oils.
Claims21
A method for controlling, mitigating, or reducing undesired vegetation belonging to one or more difficult to control weed species, the method comprising:
- applying to the undesired vegetation or its environment an herbicidally effective amount of an oil dispersion formulation, the oil dispersion formulation comprising aminocyclopyrachlor in a free-acid form suspended or dispersed in one or more oils, the oil dispersion formulation comprising from about 15 wt. % to about 70 wt. % of the one or more oils, and wherein the oil dispersion formulation is substantially free of water.
An oil dispersion (OD) formulation for the treatment of undesired vegetation belonging to one or more difficult to control weed species, the OD formulation comprising:
- from about 5 wt. % to about 30 wt. % aminocyclopyrachlor in a free-acid form;
- from about 4 wt. % to about 20 wt. % of at least one emulsifier;
- from about 2.5 wt. % to about 25 wt. % of at least one surfactant;
- from about 5 wt. % to about 55 wt. % of at least one penetration promoter.
A spray solution for the treatment of undesired vegetation belonging to one or more difficult to control weed species, the spray solution comprising an OD formulation and water, OD formulation comprising:
- from about 5 wt. % to about 30 wt. % aminocyclopyrachlor in a free-acid form;
- from about 4 wt. % to about 20 wt. % of at least one emulsifier;
- from about 2.5 wt. % to about 25 wt. % of at least one surfactant;
- from about 5 wt. % to about 55 wt. % of at least one penetration promoter.
A method for controlling, mitigating, or reducing undesired vegetation belonging to one or more difficult to control weed species, the method comprising:
- applying to the undesired vegetation or its environment an herbicidally effective amount of an oil dispersion formulation, the oil dispersion formulation comprising an active ingredient component suspended or dispersed in one or more oils, wherein the active ingredient component consists essentially of aminocyclopyrachlor in a free-acid form.
