Abstract
Herbicidal compositions are described containing either 2-(2,4-dichlorophenyl)methyl-4,4-dimethyl-3-isoxazolidinone (2,4-DC) or 2-(2,5-dichlorophenyl)methyl-4,4-dimethyl-3-isoxazolidinone (2,5-DC). Compositions containing 2,4-DC or 2,5-DC and a second herbicide are also disclosed, where the combination does not contain both 2,4-DC and 2,5-DC. Methods of using the same compositions are also described.
Claims13
A method of controlling undesired vegetation in a wheat crop comprising applying to the locus of said vegetation an herbicidally-effective amount of a composition comprising a first herbicide 2-(2,4-dichlorophenyl) methyl-4,4-dimethyl-3-isoxazolidinone (“2,4-DC”) and optionally at least a second herbicide, and agriculturally acceptable salts or esters thereof, the second herbicide being selected from the group consisting of:
- bromoxynil, diflufenican, metsulfuron-methyl, napropamide, pyroxasulfone, thifensulfuron-methyl, sulfentrazone;
- and mixtures of the two or more said second herbicide;
- wherein the first herbicide is applied at a rate of at least 50 g ai/ha and there is no observed phytotoxicity of greater than 10% to the wheat crop 7 to 28 days after treatment (DAT).
