Herbicidal composition comprising a pyrandione herbicide and a co-herbicide The present invention relates to a herbicidal composition comprising as active ingredient a mixture of a) a herbicidally effective amount of a compound of formula (I) wherein: R 1 is methyl, ethyl, n-propyl, halogen, difluoromethoxy, trifluoromethoxy or trifluoromethyl, R 2 is phenyl or phenyl substituted by C 1 -C 4 alkyl, C 1 -C 4 haloalkyl, C 1 -C 4 alkoxy, C 1 -C 4 haloalkoxy or halogen, R 4 , R 5 , R 6 and R 7 , independently of each other, are hydrogen or C 1 -C 4 alkyl, Y is O, and G is hydrogen, an alkali metal, alkaline earth metal, sulfonium, or ammonium, or G is a latentiating group which is C(O)—R a or C(0)-O—R b ; and b) a co-herbicide selected from the group consisting of fenoxasulfone, ipfencarbazone, propyrisulfuron, and N-[2-[(4,6-dimethoxy-1,3,5-triazin-2-yl)carbonyl]-6-fluorophenyl]-1,1-difluoro-N-methylmethanesulfonamide. The herbicidal composition is typically for controlling grasses and weeds in crops of useful plants, especially for controlling Echinochloa and/or Leptochloa weeds in crops of rice. |
