Bicyclic imides of formulae (I) and (II), and their agriculturally-suitable salts, are disclosed which are useful for controlling undesirable vegetation, 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-C4alkyl); or N(C1-C4haloalkyl); 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 of formulae (I) and (II).

Imides bicycliques de formule (I) et (II) et leurs sels à usage agricole servant à lutter contre la végétation indésirable, où G représente O ou S; n et m sont chacun indépendamment 0, 1, 2 ou 3 sous réserve que m + n soit 2 ou 3; q est 1 ou 2; X est CH¿2?; CH (halogène); CHOCH¿2?F; CHOCF¿3?; CHOCH¿2?CF¿3?; O; S(O)¿0-2?; NH; N(C¿1?-C¿4? alkyle); ou N(haloalkyle C¿1?-C¿4?); et R?1¿, R?2¿ et Q sont tels que définis dans la présentation de l'invention. L'invention porte également sur des compositions contenant lesdits imides et des méthodes de lutte contre la végétation indésirable consistant à appliquer sur la zone à protéger une dose efficace de ces même imides.
