Disclosed are herbicidal compositions containing a combination of the compound 2-[1-(3-transchloroallyloxyimino)propyl]-5-(2-ethylthiopropyl)-3-hydroxy-2 -cyclohexene-1-one (or a herbicidally effective salt thereof) and the compound 2-[7-fluoro-3,4-dihydro-3-oxo-4-(2-propynyl)-2H-1,4-benzoxazine-6-yl]-4,5, 6,7-tetrahydro-1H-isoindole-1,3(2H)-dione. It has been found that this combination synergistically interacts so as to accelerate the post-emergent herbicidal activity of 2-[1-(3-trans-chloroallyloxyimino)propyl]-5-(2-ethylthiopropyl)-3-hydroxy- 2-cyclohexen-1-one (or its salt) against grassy weeds.
