A compound of the formula:
- wherein
- R.sub.f is lower perfluoroalkyl;
- R.sub.2 and R.sub.3 each independently is
- (1) a hydrocarbon group selected from alkyl;
- alkenyl;
- cycloalkyl;
- phenyl;
- and phenyl substituted by up to 3 groups selected from alkyl, alkoxy, alkylthio, mono- or dialkylamino, and halo wherein each alkyl moiety has 1 to 4 carbon atoms;
- (2) haloalkyl;
- (3) alkoxy;
- and
- (4) a heterocyclic group which can contain only carbon, hydrogen, oxygen, nitrogen, and sulfur, but which must contain at least one ring atom selected from oxygen, nitrogen, and sulfur;
- R.sub.4 and R.sub.5 each independently is hydrogen, alkyl, or halo;
- and
- R.sub.6 is hydrogen, alkoxycarbonyl, (alkylthio)carbonyl, (haloalkylthio)carbonyl, haloalkoxycarbonyl, or phenoxycarbonyl;
- and agriculturally acceptable salts of the acid form compounds;
- provided that
