wherein R1 is H, C1-C3 alkyl or OCH3;
R2 is H or C1-C3 alkyl;
R3 is
<CHEM>
R4 is C1-C3 alkyl;
R5 is H, F, Cl, Br, NO2, CH3, OCH3 or CF3; X is CH3, C2H5, CH2OCH3, C1-3 alkoxy, OCH2CH2OCH3, CF3 or SCH3;
Y is CH3 or OCH3; and
Z is CH orN;
and their agriculturally suitable salts, provided that R1 and R2 are not both H, exhibit activity as general and selective herbicides and as plant growth regulants. For such uses the compounds may be formulated into compositions in conventional manner.
<??>The novel compounds may be made by reacting together corresponding compounds of formulae R3SO2NCO and
