The application also discloses a method of controlling undesired vegetation in a crop by applying to the locus of such vegetation a herbicidally effective amount of a herbicidal composition.
1. A herbicidal composition containing a first herbicide beflubutamid (BFL), or an optically enriched form thereof, and a second herbicide, wherein the second herbicide is selected from 2-(2,4-dichlorophenyl)methyl-4,4-dimethyl-3-isoxazolidinone (DCI); including isomers and/or C 1-8 -alkyl esters and/or salts thereof, and wherein the BFL and DCI together yields better weed control in comparison to either BFL alone or DCI alone.
2. The herbicidal composition according to claim 1 , wherein the first herbicide is beflubutamid enriched with respect to the (−)-enantiomer.
3. The herbicidal composition of claim 1 further comprising at least one formulation component selected from formulation agents for emulsifiable concentrate formulations, formulation agents for suspension concentrate formulations, and formulation agents for capsule suspension formulations.
4. A method of controlling undesired vegetation in a crop, wherein the method includes applying to the locus of said vegetation a herbicidally effective amount of the herbicidal composition according to claim 1 .
5. The method according to claim 4 , wherein the undesired vegetation is present together with a crop selected from wheat, barley, rye, triticale, corn, soybean and rice.
6. The method according to claim 4 , wherein the herbicidal composition comprising beflubutamid in combination with 2-(2,4-dichlorophenyl)methyl-4,4-dimethyl-3-isoxazolidinone, and wherein beflubutamid is applied in an amount of 30-400 g ai/ha, 45-320 g ai/ha, or 60-250 g ai/ha, and 2-(2,4-dichlorophenyl)methyl-4,4-dimethyl-3-isoxazolidinone is applied in an amount of 10-500 g ai/ha, 45-400 g ai/ha, or 20-300 g ai/ha.
7. The herbicidal composition of claim 2 further comprising at least one formulation component selected from formulation agents for emulsifiable concentrate formulations, formulation agents for suspension concentrate formulations, and formulation agents for capsule suspension formulations.
8. A method of controlling undesired vegetation in a crop, wherein the method includes applying to the locus of said vegetation a herbicidally effective amount of the herbicidal composition according to claim 2 .
9. A method of controlling undesired vegetation in a crop, wherein the method includes applying to the locus of said vegetation a herbicidally effective amount of the herbicidal composition according to claim 3 .
10. The method according to claim 8 , wherein the undesired vegetation is present together with a crop selected from wheat, barley, rye, triticale, corn, soybean and rice.
11. The method according to claim 9 , wherein the undesired vegetation is present together with a crop selected from wheat, barley, rye, triticale, corn, soybean and rice.
12. The method according to claim 5 , wherein the herbicidal composition comprising beflubutamid in combination with 2-(2,4-dichlorophenyl)methyl-4,4-dimethyl-3-isoxazolidinone, and wherein beflubutamid is applied in an amount of 30-400 g ai/ha, 45-320 g ai/ha, or 60-250 g ai/ha, and 2-(2,4-dichlorophenyl)methyl-4,4-dimethyl-3-isoxazolidinone is applied in an amount of 10-500 g ai/ha, 45-400 g ai/ha, or 20-300 g ai/ha.
13. The method according to claim 10 , wherein the herbicidal composition comprising beflubutamid in combination with 2-(2,4-dichlorophenyl)methyl-4,4-dimethyl-3-isoxazolidinone, and wherein beflubutamid is applied in an amount of 30-400 g ai/ha, 45-320 g ai/ha, or 60-250 g ai/ha, and 2-(2,4-dichlorophenyl)methyl-4,4-dimethyl-3-isoxazolidinone is applied in an amount of 10-500 g ai/ha, 45-400 g ai/ha, or 20-300 g ai/ha.
