This invention relates to certain substituted and unsubstituted alpha-aryl-alpha-phenylethyl-1-H-1,2,4-triazole-1-propanenitriles, their enantiomorphs, acid addition salts and metal salt complexes which are active broad-spectrum systemic fungicides effective in controlling phytopathogenic fungi such as corn helminthosporium, barley helminthosporium, cucumber downy mildew, cucumber powdery mildew, cucumber anthracnose, botrytis, tomato early blight, tomato late blight, grape downy mildew, bean powdery mildew, peanut cercospora, rice blast, rice sheath blight, wheat leaf rust, wheat septoria nodorum, wheat powdery mildew and wheat stem rust. The invention also concerns a method of preparing alpha-aryl-alpha-triazolylmethyl-acetonitrile compounds by reacting an aryl acetonitrile compound with a halomethyltriazole.
