Trisubstituted cyanoguanidines of the formula <IMAGE> in which R1 represents an optionally substituted phenyl or phenylalkyl radical, an alkyl radical with more than 1 carbon atom, a substituted alkyl radical, an alkenyl or alkinyl radical or an optionally substituted cycloalkyl radical, R2 represents an optionally substituted alkyl radical or an alkenyl or alkinyl radical and R3 represents an optionally substituted alkyl radical, an alkenyl or alkinyl radical, an optionally substituted cycloalkyl radical or an optionally substituted phenyl or phenylalkyl radical, or R2 and R3, together with the nitrogen atom to which they are bonded, represent an optionally substituted heterocyclic radical, which optionally contains an oxygen atom as a further hetero-atom, or a physiologically acceptable acid addition salt thereof, which possess fungicidal properties. Processes for their preparation are also taught. |
