Abstract: This invention relates to 2-aryl-2-cyano-2-(heterocyclylalkyl)ethyl-1,2,4-triazoles of the formula ##STR1## wherein Ar is an optionally substituted aryl group, Het is an optionally substituted five or six membered saturated or unsaturated heterocyclic ring containing one, two or three heteroatoms selected from oxygen, nitrogen and sulfur, or is a bicyclic unsaturated ring system containing up to ten atoms including one heteroatom selected from oxygen, nitrogen and sulfur, R is hydrogen or alkyl, n is zero or an integer of at least one, and the agronomically acceptable enantiomorphs, geometric isomers, acid addition salts and metal salt complexes thereof.

Abstract: This invention relates to alpha-alkyl-alpha-(4-halophenyl)-1H-1,2,4-triazole-1-propanenitriles, their enantiomorphs, acid addition salts and metal salt complexes. These compounds, enantiomorphs, salts and complexes are highly active broad spectrum systemic fungicides effective in controlling phytopathogenicfungi such as barley spot blotch, grape, wheat and bean powdery mildews, grape downy mildew, rice blast, tomato and potato late blights and wheat stem rust.

Abstract: This invention relates to alpha-(2-alkoxyphenyl)-alpha-alkyl-1H-1,2,4-triazole-1-propanenitriles and derivatives, their enantiomorphs, acid addition salts and metal salt complexes. These compounds, enantiomorphs, salts and complexes are highly active broad-spectrum systemic fungicides effective in controlling phytopathogenic fungi such as barley helminthosporium, cucumber downy mildew, cucumber powdery mildew, grape downy mildew, peanut cercospora, rice blast, wheat powdery mildew and wheat stem rust. The compounds have protective and curative activity against rice blast when they are applied foliarly or systemically and have superior residual activity against rice blast via foliar application.

Abstract: Compounds of the formula: ##STR1## wherein X is hydrogen, halo, trihalomethyl, alkyl, nitro or cyano; X.sup.1 is hydrogen, halo, or trihalomethyl; R.sup.1 and R.sup.2 are hydrogen, alkyl, phenyl or benzyl; n is 1 to 5, and Z is nitro, and compositions containing these compounds exhibit herbicidal activity.
