Abstract
The present invention relates to an herbicidal composition particularly stable at lower temperatures. The present invention provides a stable herbicidal composition comprising at least one pesticide in its salt form and a crystal habit modifying system comprising an alkoxylated alcohol and a polymer. Further the invention relates to a stable herbicidal composition comprising at least two pesticides in their salt form and a crystal habit modifying system comprising an alkoxylated alcohol and a polymer.
Claims14
A stable aqueous composition comprising,
- at least one herbicide in its salt form, wherein said herbicide is selected from the group consisting of acifluorfen, bentazone, and combinations thereof as the only herbicidal active ingredients in said composition and
- a crystal habit modifying system comprising an alkoxylated alcohol and a polymer, wherein the alkoxylated alcohol is butyl cellosolve;
- and wherein the polymer is selected from esters of polyalkoxylated alcohols, guar gum, xanthan gum, HP guar, and hydroxyethyl cellulose;
- wherein said polymer is present in an amount from about 0.1 to about 0.2% by weight of the composition;
- wherein said composition is stable at −10° C.
A stable aqueous composition comprising,
- 1-25 wt. % acifluorfen salt and 1-50 wt. % bentazone salt based on the total weight of the composition as the only herbicidal active ingredients in said composition and
- a crystal habit modifying system comprising an alkoxylated alcohol and a polymer, wherein the alkoxylated alcohol is butyl cellosolve;
- and wherein the polymer is selected from the group consisting of esters of polyakoxylated alcohols, HP guar, and hydroxyethyl cellulose;
- wherein said polymer is present in an amount from about 0.1 to about 0.2% by weight of the composition;
- and wherein said composition includes 1-15 wt. % of said butyl cellosolve based on the total weight of the composition;
- wherein said composition is stable at −10° C.
A stable aqueous composition consisting of,
- at least one herbicide in its salt form, wherein said herbicide is selected from the group consisting of acifluorfen, bentazone, and combinations thereof as the only herbicidal active ingredients in said composition and
- a crystal habit modifying system consisting of an alkoxylated alcohol and a polymer, wherein the alkoxylated alcohol is butyl cellosolve;
- and wherein the polymer is selected from esters of polyalkoxylated alcohols, guar gum, xanthan gum, HP guar, and hydroxyethyl cellulose;
- wherein said polymer is present in an amount from about 0.1 to about 0.2% by weight of the composition;
- water;
- and
- optionally at least one surfactant,
- wherein said composition is stable at −10° C.
