The present invention relates to a compound of the formula (I) or salt thereofin whichR<1 >is identical or different at each occurrence and is H, halogen, CN, nitro, SF5, (C1-C8)alkyl, (C2-C8)alkenyl, (C2-C8)alkynyl, (C1-C8)alkoxy, [(C1-C8)alkyl]-carbonyl or (C1-C8)alkylsulfonyl, each of the radicals being unsubstituted or substituted,or is S(O)p-R<7>, wherep=0, 1 or 2 andR<7 >is (C1-C8)alkyl, (C1-C8)haloalkyl or NR<8>R<9>, whereR<8 >and R<9 >independently of one another are identical or different and are H, (C1-C8)alkyl, (C2-C8)alkenyl, (C7-C10)arylalkyl, (C7-C10)alkylaryl or (C6-C10)aryl, each of the last-mentioned five radicals being unsubstituted or substituted,or is a group of the formulawhere R<10 >is (C1-C8)alkyl which is unsubstituted or substituted, andW=O or S,A is optionally substituted aryl or an optionally substituted heterocyclic radical,X is O or S,R<2>,R<3>,R<4>, and R<5 >are identical or different and are H, halogen, CN, (C1-C8)alkoxy or (C1-C8)alkyl, each of the two last-mentioned radicals being unsubstituted or substituted,m is 0 or 1,R<6 >is H, (C1-C8)alkyl, (C1-C8)alkoxy, (C2-C8)alkenyl or (C2-C8)alkynyl, each of the four last-mentioned radicals being unsubstituted or substituted, or is hydroxyl or an acyl radical, andB is an acyl radical,or B and R<6 >together form a 4- or 5-membered chain,with the exception of N-hydroxy-N-[(6-phenoxy-2-pyridyl)methyl]-acetamide and its salts.The compounds of the invention are suitable, for example, as herbicides and growth regulators.
