The present invention provides a method for post-emergence selective crabgrass control by applying a composition comprising a first herbicide and a second herbicide in which the first herbicide is 2,4-dinitro-N3,N3-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 to a locus where one to two leaf growth stage crabgrass is present.
