Herbicidal composition
View Patent ↗The present invention provides an herbicidal composition comprising a first herbicide and a second herbicide in which the first herbicide is 2,4-dinitro-N 3 ,N 3 -dipropyl-6-(trifluoromethyl)-1,3-benzenediamine and N-[2,4-dichloro-5-[4-(difluoromethyl)-4,5-dihydro-3-methyl-5-oxo-1H-1,2,4-triazol-1-yl]phenyl]methanesulfonamide and a method of use.
1. An herbicidal composition comprising a first herbicide and a second herbicide in which the first herbicide is 2,4-dinitro-N 3 ,N 3 -dipropyl-6-(trifluoromethyl)-1,3-benzenediamine and the second herbicide is N-[2,4-dichloro-5-[4-(difluoromethyl)-4,5-dihydro-3-methyl-5-oxo-1H-1,2,4-triazol-1-yl]phenyl]methanesulfonamide.
2. The composition according to claim 1 wherein the ratio of 2,4-dinitro-N 3 ,N 3 -dipropyl-6-(trifluoromethyl)-1,3-benzenediamine to N-[2,4-dichloro-5-[4-(difluoromethyl)-4,5-dihydro-3-methyl-5-oxo-1H-1,2,4-triazol-1-yl]phenyl]methanesulfonamide is in the range of from 10:1 to 1:1.
3. The composition according to claim 2 wherein the ratio of 2,4-dinitro-N 3 ,N 3 -dipropyl-6-(trifluoromethyl)-1,3-benzenediamine to N-[2,4-dichloro-5-[4-(difluoromethyl)-4,5-dihydro-3-methyl-5-oxo-1H-1,2,4-triazol-1-yl]phenyl]methanesulfonamide is in the range of from 7:1 to 2:1.
4. A method for controlling weeds comprising applying a composition of claim 1 to a locus where weeds are present or are expected to be present.
5. A method according to claim 4 wherein the ratio of 2,4-dinitro-N 3 ,N 3 -dipropyl-6-(trifluoromethyl)-1,3-benzenediamine to N-[2,4-dichloro-5-[4-(difluoromethyl)-4,5-dihydro-3-methyl-5-oxo-1H-1,2,4-triazol-1-yl]phenyl]methanesulfonamide in the composition is in the range of from 10:1 to 1:1.
6. A method according to claim 5 wherein the ratio of 2,4-dinitro-N 3 ,N 3 -dipropyl-6-(trifluoromethyl)-1,3-benzenediamine to N-[2,4-dichloro-5-[4-(difluoromethyl)-4,5-dihydro-3-methyl-5-oxo-1H-1,2,4-triazol-1-yl]phenyl]methanesulfonamide is in the range of from 7:1 to 2:1.
