Patent ID: 7196229

Claim:
A benzoylcyclohexenone derivative of the formula I in which the variables are as defined below: R 1 is C 3 –C 6 -alkyl, C 3 –C 6 -haloalkyl or C 1 –C 4 -alkoxy-C 1 –C 4 -alkyl; R 2 is C 1 –C 6 -alkyl or C 1 –C 6 -haloalkyl; R 3 is halogen, cyano, nitro, C 1 –C 6 -alkyl, C 1 –C 6 -haloalkyl, C 1 –C 6 -haloalkoxy, C 1 –C 6 haloalkylthio, C 1 –C 6 -alkylsulfinyl, C 1 –C 6 -haloalkylsulfinyl, C 1 –C 6 -alkylsul-fonyl or C 1 –C 6 -haloalkylsulfonyl; R 4 is hydroxyl or SR 11 ; R 5 , R 6 , R 9 R 10 independently of one another are hydrogen or C 1 –C 4 -alkyl; R 7 , R 8 independently of one another are hydrogen or C 1 –C 4 -alkyl or together with the carbon atom to which they are attached form a carbonyl group; n is 1 or 2; where R 11 is C 1 –C 4 -alkyl or phenyl which is optionally partially or fully halogenated and/or optionally carries one to three of the following groups: nitro, cyano, C 1 –C 4 -alkyl, C 1 –C 4 -haloalkyl, C 1 –C 4 -alkoxy or C 1 –C 4 -haloalkoxy; and its agriculturally useful salts.
