Fungicidal activity of a series of 1‐substituted‐1‐aryl‐2‐triazol‐1‐yl‐ethanols

Twenty‐four I‐substituted‐I‐aryl‐2‐triazol‐I‐yl‐ethanols were prepared by the reaction between acetylenic, propargylic or allylic organometallics and aryl triazolylmethyl ketones. These were tested for antifungal activity against ten phytopathogenic fungi of different taxonomic classes. EC 80 values were determined for the seven most active compounds and for two commercial compounds, hexaconazole and flusilazole. In these tests, the fungicidal activity of the new compounds was generally lower than that of the two reference triazoles except for two products which were more active than hexaconazole and flusilazole against powdery mildew on barley.
