Abstract
The present invention relates generally low volatility herbicidal compositions comprising at least one auxin herbicide and at least one monocarboxylic acid, or monocarboxylate thereof. The invention further relates generally to methods for preparing and using such low volatility herbicidal compositions, including methods for controlling auxin-susceptible plant growth on agricultural and non-agricultural lands.
Claims54
A method for preparing an herbicidal composition, the method comprising:
- combining (i) an auxin herbicide, or an agriculturally acceptable salt or ester thereof, (ii) a monocarboxylate, and (iii) water, wherein the auxin herbicide is selected from dicamba, or an agriculturally acceptable salt or ester thereof, 2,4-D, or an agriculturally acceptable salt or ester thereof, and mixtures thereof, and the monocarboxylate is selected from the group consisting of a formate salt, an acetate salt, a propionate salt, a benzoate salt, and combinations thereof;
- wherein said combining comprises:
- providing a liquid herbicidal composition concentrate comprising from about 120 to about 600 g a.e./L of auxin herbicide;
- diluting the herbicidal composition concentrate comprising the auxin herbicide with water, thereby forming an herbicidal composition comprising from about 0.1 g a.e./L to about 50 g a.e./L of auxin herbicide;
- and
- adding the monocarboxylate to the herbicidal composition, wherein the herbicidal composition comprises an amount of the monocarboxylate sufficient to provide enhanced protection from off-target crop injury as compared to an otherwise identical herbicidal composition lacking the monocarboxylate while maintaining comparable herbicidal efficacy on auxin-susceptible plants located in the target area.

- providing a liquid herbicidal composition concentrate comprising from about 120 to about 600 g a.e./L of auxin herbicide;
- adding the monocarboxylate to the herbicidal composition concentrate;
- and
- diluting the herbicidal composition concentrate comprising the auxin herbicide and monocarboxylate, with water, thereby forming an herbicidal composition comprising from about 0.1 g a.e./L to about 50 g a.e./L of auxin herbicide, wherein the herbicidal composition comprises an amount of the monocarboxylate sufficient to provide enhanced protection from off-target crop injury as compared to an otherwise identical herbicidal composition lacking the monocarboxylate while maintaining comparable herbicidal efficacy on auxin-susceptible plants located in the target area.

A method for preparing an herbicidal composition, the method comprising:
- combining (i) an auxin herbicide, or an agriculturally acceptable salt or ester thereof, (ii) a monocarboxylic acid, (iii) a neutralizing base, and (iv) water, wherein the auxin herbicide is selected from the group consisting of dicamba, or an agriculturally acceptable salt or ester thereof, 2,4-D, or an agriculturally acceptable salt or ester thereof, and mixtures thereof, and the monocarboxylic acid is selected from the group consisting of formic acid, acetic acid, propionic acid, benzoic acid, and combinations thereof, wherein said combining comprises:
- providing a liquid herbicidal composition concentrate comprising from about 20 to about 600 g a.e./L of auxin herbicide;
- adding the monocarboxylic acid to the herbicidal composition concentrate comprising the auxin herbicide, followed by adding the neutralizing base to the herbicidal composition concentrate;
- and
- diluting the herbicidal composition concentrate, thereby forming an herbicidal composition comprising from about 0.1 g a.e./L to about 50 g a.e./L of auxin herbicide, wherein the herbicidal composition comprises an amount of the monocarboxylic acid sufficient to provide enhanced protection from off-target crop injury as compared to an otherwise identical herbicidal composition lacking the monocarboxylic acid while maintaining comparable herbicidal efficacy on auxin-susceptible plants located in the target area.
