The invention relates to cyclohexenondioxothiochromanoyl derivatives of formula (I) wherein the variables have the following meanings: X is oxygen, sulphur, S=O, S(=O)2, CR<4>R<5>, C=O or C=NR<6>; R<1> is hydrogen, nitro, halogen, cyano, alkyl, alkyl halide, alkoxy, halogenalkoxy, alkylthio, halogenalkylthio, alkylsulfinyl, halogenalkylsulfinyl, alkylsulfonyl, halogenalkylsulfonyl, optionally substituted aminosulfonyl or optionally substituted sulfonylamino; R<2> is alkyl, alkyl halide, alkoxy or halogenalkoxy; R<3> is hydrogen, alkyl or halogen; and R<4>, R<5> are hydrogen, nitro, halogen, cyano, alkyl, alkyl halide, alkoxy, halogenalkoxy, alkylthio, halogenalkylthio, alkylsulfinyl, halogenalkylsulfinyl, alkylsulfonyl, halogenalkylsulfonyl or substituted amino; or R<4> and R<5> together form a chain which can be substituted and/or interrupted by oxygen or sulphur; or an optionally substituted methylide group; l is 0 to 4; R<7> is substituted (3-oxo-1-cyclohexen-2-yl)-carbonyl or substituted (1,3-dioxo-2-cyclohexyl-methylides. The invention also relates to the agriculturally usable salts of said derivatives, to methods for producing the derivatives, to substances containing them, and to the use of the derivatives or substances containing them for combating undesirable plants. |
