The present invention relates to one of the two geometrical isomers (a compound defined as I-A isomer in the description below) of a triazole compound represented by the formula (I) or (II), ##STR1## wherein R.sub.1 is a hydrogen atom, a C.sub.1 -C.sub.4 alkyl, C.sub.3 -C.sub.4 alkenyl or 2-propynyl group, R.sub.2 is a C.sub.1 -C.sub.6 alkyl, cyclopropyl or 1-methylcyclopropyl group, R.sub.3, which may be the same or different, is a halogen atom, a C.sub.1 -C.sub.4 alkyl, halogen-substituted C.sub.1 -C.sub.3 alkyl, C.sub.1 -C.sub.4 alkoxy, phenoxy, phenyl, cyano or nitro group, n is an integer of 0 to 3, and the term, halogen, means chlorine, bromine and fluorine atoms, its salts, production thereof and a fungicide, herbicide and/or plant growth regulator for agriculture and horticulture containing said compound as an active ingredient.

Geometrical isomer of 1-substituted-1-triazolystyrenes

Geometrical isomer of 1-substituted-1-triazolylstyrenes, and their

A process for producing a triazolylvinyl ketone compound of the formula: ##STR1## wherein X is a hydrogen or chlorine atom, comprising heating a compound of the formula: ##STR2## wherein X is as defined above. The triazolylvinyl ketone compound is useful as agricultural fungicides.

Production of triazolylvinyl ketones

1-Phenyl-2-azolyl-4,4-dimethyl-1-penten-3-ols of the formula: ##STR1## wherein X, which may be same or different, is an alkyl (C.sub.1 -C.sub.4), cyano, alkoxy (C.sub.1 -C.sub.4), phenoxy, phenyl group, halogen atom, n is zero or an integer of 1 to 2, A.sub.Z is an imidazole group of the formula ##STR2## or a triazole group of the formula ##STR3## and salt thereof, which show high fungicidal activities without any material toxicity to mammals and plants and can be produced by reacting the corresponding 3-ketone compound with a reducing agent.
