The invention relates to fungicidal compositions which comprise a carrier and, as active ingredient, an indole derivative of the formula ##STR1## in which R is a substituted phenyl group; R.sup.3 and R.sup.4 independently are hydrogen or halogen or an optionally substituted alkyl, alkoxy, cycloalkyl, phenyl or phenoxy group; R.sup.5 and R.sup.6 independently are hydrogen atom or an optionally substituted alkyl, alkoxy, cycloalkyl, phenyl or heterocyclyl group or R.sup.5 and R.sup.6 together with the interjacent nitrogen atom represent a heterocyclyl group; and R.sup.7 is hydrogen or alkyl group; and their use as fungicides. Certain of the above mentioned indole derivatives are novel and a process for the preparation of these compounds is also provided.
