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: R1 is methyl, ethyl, n-propyl, halogen, difluoromethoxy, trifluoromethoxy or trifluoromethyl, R2 is phenyl or phenyl substituted by C1-C4 alkyl, C1-C4 haloalkyl, C1-C4 alkoxy, C1-C4 haloalkoxy or halogen, R4, R5, R6 and R7, independently of each other, are hydrogen or C1-C4 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)—Ra or C(0)-O—Rb 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.
