Novel 2-nitro-5-(4-trifluoromethylphenoxy)-N-substituted benzamides optionally containing additional ring substituents, herbicidal compositions containing them and the use of the novel compounds for combating weeds particularly those in an agronomic crop area. The novel compounds are of the formula: <CHEM> wherein X is hydrogen, halogen, (C1-C4)alkyl, cyano or trifluoromethyl; Y is hydrogen or halogen; R<1> is hydrogen, hydroxy, (C1-C4)alkoxy, (C1-C4)alkyl optionally substituted with various defined substituents, or monocyciic (C5-C7)cycloalkyl; R<2> is hydrogen, (C1-C4)alkyl optionally substituted with various defined substituents, or monocyclic (C5-C7)cycloalkyl; or R<1> and R<2> can be joined to form together with the attached nitrogen atom, a saturated heterocyclic ring having 4 to 6 carbon atoms and up to one additional hetero nitrogen, oxygen or sulfur atom. |
