<p>Novel fungicidal compounds are urea derivatives of iodo alkynyls, having formula (I), in which R is H or an alkyl group having one to not more than 20 carbon atoms, Ra to Rc are H or a substituted or unsubstituted alkyl, aryl, aralkyl or cycloalkyl group having from one to not more than 20 carbons and Rc is H or alkyl when Ra or Rb is aryl, n and m are a whole number integers between 1 and 3, and X is I or Br. These compounds have shown great fungicidal activity, particularly when used in surface coating compositions, such as paint formulations, and for the protection of wood and wood type material.</p> |
