Abstract
Compounds of Formula I and their agriculturally suitable salts are disclosed which are useful for controlling undesired vegetation ##STR1## wherein Q is ##STR2## and R.sup.1 through R.sup.7, m, n, p and q are as defined in the disclosure. Also disclosed are compositions containing the compounds of Formula I and a method for controlling undesired vegetation which involves contacting the vegetation or its environment with an effective amount of a compound of Formula I.

- R.sup.5 is H, C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.6 haloalkyl, C.sub.2 -C.sub.6 alkoxyalkyl, formyl, C.sub.2 -C.sub.6 alkylcarbonyl, C.sub.2 -C.sub.6 alkoxycarbonyl, C.sub.2 -C.sub.6 alkylaminocarbonyl, C.sub.3 -C.sub.7 dialkylaminocarbonyl, C.sub.1 -C.sub.6 alkylsulfonyl or C.sub.1 -C.sub.6 haloalkylsulfonyl;
- or R.sup.5 is benzoyl or phenylsulfonyl, each optionally substituted with C.sub.1 -C.sub.3 alkyl, halogen, cyano or nitro;
- R.sup.6 is H, C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.6 haloalkyl, C.sub.3 -C.sub.6 alkenyl or C.sub.3 -C.sub.6 alkynyl;
- or R.sup.6 is phenyl or benzyl, each optionally substituted on the phenyl ring with C.sub.1 -C.sub.3 alkyl, halogen, cyano or nitro;
- R.sup.7 is H, C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.6 haloalkyl, halogen, cyano, or nitro;
- R.sup.8 is H, C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.6 haloalkyl, C3-C.sub.6 alkenyl or C.sub.3 -C.sub.6 alkynyl;
- R.sup.9 is H, C.sub.1 -C.sub.6 alkyl, C.sub.1 -C.sub.6 haloalkyl, C2-C.sub.6 alkoxyalkyl, formyl, C.sub.2 -C.sub.6 alkylcarbonyl, C.sub.2 -C.sub.6 alkoxycarbonyl, C.sub.2 -C.sub.6 alkylaminocarbonyl, C.sub.3 -C.sub.7 dialkylaminocarbonyl, C.sub.1 -C.sub.6 alkylsulfonyl or C.sub.1 -C.sub.6 haloalkylsulfonyl;
- or
