PCT No. PCT/US95/03932 Sec. 371 Date Oct. 3, 1996 Sec. 102(e) Date Oct. 3, 1996 PCT Filed Apr. 6, 1995 PCT Pub. No. WO95/27698 PCT Pub. Date Oct. 19, 1995 <IMAGE> (I) <IMAGE> (II) Bicyclic imides of formulae (I) and (II) and their agriculturally-suitable salts, are disclosed which are useful for controlling undesirable vegatation, wherein G is O or S; n and m are each independently 0; 1; 2; or 3; provided that m+n is 2 or 3; q is 1 or 2; X is CH2; CH(halogen); CF2; CHOCH2F; CHOCF3; CHOCH2CF3; O; S(O)0-2; NH; N(C1-C4 alkyl); or N(C1-C4 haloalkyl); and R1. R2, and Q are as defined in the disclosure. Also disclosed are compositions containing the bicyclic imides of formulae (I) and (II) and a method for controlling growth of undesired vegetation comprising applying to the locus to be protected an effective amount, of the bicyclic imides formulae (I) and (II).
