Abstract

A method of combating fungi which comprises applying to such fungi or to a fungus habitat a fungicidally effective amount of a thienylurea derivative of the formula ##STR1## in which X is oxygen or sulphur, PA0 R is C.sub.1 -C.sub.4 -alkoxy, PA0 R.sup.1 is C.sub.3 -C.sub.4 -alkyl, and PA0 R.sup.2 and R.sup.3 each independently is C.sub.1 -C.sub.4 -alkyl and one of them may also be hydrogen.
