摘要:
Compositions containing heterocyclic compounds are described which include an amide group, can act as herbicides and be defined by the general formula: ##STR1## in which: R is a linear or branched alkyl group containing from 1 to 6 carbon atoms;the phenyl group;a phenyl group having a substituent, or several substituents which may be identical or different from each other, selected from the halogens and alkyl (C.sub.1 -C.sub.4), oxyalkyl (C.sub.1 -C.sub.4), halogenoalkyl (C.sub.1 -C.sub.4) and nitro groups;R.sub.1 is a linear or branched alkyl group containing from 1 to 12 carbon atoms;a linear or branched alkyl group containing from 1 to 12 carbon atoms substituted with one or more halogen atoms;a cycloalkyl group containing from 3 to 8 carbon atoms;a (methyleneoxy)alkyl (C.sub.1 -C.sub.5) group;a (methyleneoxy)phenyl group;a (methyleneoxy)phenyl group having one or more substituents in the ring which are selected from halogen, (C.sub.1 -C.sub.4) alkyl, (C.sub.1 -C.sub.4) halogenoalkyl groups;the phenyl group;the benzyl group;a phenyl or benzyl group having one or more substituents, which may be identical or different from each other, selected from halogen atoms and (C.sub.1 -C.sub.4) alkyl, (C.sub.1 -C.sub.4) halogenalkyl, (C.sub.1 -C.sub.4) oxyalkyl and nitro groups;or R.sub.1 is definable by: ##STR2## where R' is a (C.sub.1 -C.sub.2) alkylene group and R" and R"' are linear or branched alkyl groups containing from 1 to 5 carbon atoms; or R" and R"' taken together with the nitrogen atom to which they are connected form a 5 or 6 membered heterocyclic ring possibly containing another heteroatom selected from O, N and S.
