Patent Images
1. A herbicidal composition concentrate comprising:
- dicamba, or an agriculturally acceptable salt or ester thereof; and
a potassium or sodium monocarboxylate of a monocarboxylic acid;
wherein;
the concentrate comprises an amount of the potassium or sodium monocarboxylate sufficient to reduce the concentration of volatilized dicamba in the vapor phase surrounding a diluted version of the concentrate relative to the concentration of volatilized dicamba in the vapor phase surrounding an otherwise identical diluted version of the concentrate lacking the potassium or sodium monocarboxylate.

34. A herbicidal composition concentrate comprising:
-
(a) dicamba, or an agriculturally acceptable salt or ester thereof; (b) at least one monocarboxylic acid; and (c) a neutralizing base, wherein the neutralizing base is an alkali metal hydroxide selected from potassium hydroxide, sodium hydroxide, or a mixture thereof, wherein; the concentrate comprises an amount of the monocarboxylic acid and neutralizing base sufficient to reduce the concentration of volatilized dicamba in the vapor phase surrounding a diluted version of the concentrate relative to the concentration of volatilized dicamba in the vapor phase surrounding an otherwise identical diluted version of the concentrate lacking the monocarboxylic acid, and neutralizing base.

35. A herbicidal composition comprising:
-
(a) dicamba or an agriculturally acceptable salt or ester thereof; (b) at least one monocarboxylic acid, or a monocarboxylate thereof; (c) a neutralizing base, wherein the neutralizing base is an alkali metal hydroxide selected from potassium hydroxide, sodium hydroxide, or a mixture thereof; and (d) water; wherein; the composition comprises an amount of the monocarboxylic acid and neutralizing base, or an amount of the monocarboxylate, sufficient to reduce the concentration of volatilized dicamba in the vapor phase surrounding the composition relative to the concentration of volatilized dicamba in the vapor phase surrounding an otherwise identical composition lacking the monocarboxylic acid and neutralizing base, or monocarboxylate. - View Dependent Claims (36, 37, 38, 39, 40, 41, 42, 43, 44, 45)
