[Study of the phytoiatric antifungal activity of derivatives of 2- and 4-aminophenylthioacetonitrile and ethyl 4-aminophenylthioacetate].

Some N-acyl and N-carbamoyl-derivatives of 2-, of 4-amino-phenylthioacetonitrile and of ethyl 4-aminophenylthioacetate, and also some N-thiocarbamoylderivatives of the latter were prepared in order to test their antimycotic activity against representative plant parasites. The substances, (I-XXVI), mostly unknown, were subjected to in vitro and in vivo tests (in preventive phase). Some of the compounds studied, especially the 2-aminophenylthioacetonitrilic derivatives, showed in the in vivo tests interesting activity and good specificy against P. viticola.
