    摘要: 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, difuoromethoxy, 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.
