Herbicidal composition and method of use thereof

An agricultural dry granular concentrate composition that contains mesotrione and pyridate, the dry granular concentrate composition comprising:

• from 10 to 55 parts by weight mesotrione,
• from 45 to 90 parts by weight pyridate, wherein a weight total of mesotrione and pyridate is 100 parts,
• at least two different surfactants, wherein the surfactants are an alkyl sulfate and a ligninsulfonate or an alkyl naphthalene sulfonate and a polymer condensate of the alkyl naphthalene sulfonate with formaldehyde, wherein the total surfactant concentration is 8.5 to 12% by weight, and
• less than 2 weight percent water based on total weight dry granular concentrate composition.

A method of controlling undesirable vegetation, the method comprising:

• providing a dry granular concentrate composition that comprises:
• from 10 to 55 parts by weight mesotrione,
• from 45 to 90 parts by weight pyridate, wherein a weight total of mesotrione and pyridate is 100 parts, wherein the mesotrione is present at 50 g/kg to 420 g/kg of the dry granular concentrate composition, and wherein the pyridate is present at 50 g/kg to 725 g/kg of the dry granular concentrate composition;
• at least two different surfactants, wherein the surfactants are an alkyl sulfate and a ligninsulfonate or an alkyl naphthalene sulfonate and a polymer condensate of the alkyl naphthalene sulfonate with formaldehyde, wherein the total surfactant concentration is 8.5 to 12% by weight, and
• filler, and
• less than 2 weight percent water based on total weight of the dry granular concentrate composition,
• combining the dry granular concentrate composition with water to form a diluted herbicide composition, and
• applying the diluted herbicide composition to resistant undesirable vegetation associated with a crop plant, a habitat of a crop plant, or a combination thereof at an application rate of 2 to 3 ounces/acre of mesotrione and 3 to 7 ounces/acre of pyridate.
