✦ Synopsis

Phenylthio)acetohydroxamie acids have been recently reported to possess fungicidal properties against phytopathogenie moulds (ZAYED et al., 1965(ZAYED et al., , 1966)). It has been shown that the transformation of the thiogroup into sulphonylgroup resulted in complete disappearance of the fungicidal activity. The presence of a halogen atom (C1 or Br) in the para-position of the phenyl ring was found to increase the fungitoxic effect. For completion of our knowledge about the relation between the chemical constitution and biological activity, a number of substituted thioacetohydroxamic acids as well as some (phenylthio)alkanoylhydroxamic acids now have been tested for their effect on the myeelial growth of some phytopathogenic fungi.
