Geometrical isomer of 1-substituted-1-triazolylstyrenes, and their production and use as fungicide, herbicide and/or plant growth regulant

摘要

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), <IMAGE> (I) <IMAGE> (II) wherein R1 is a hydrogen atom, a C1-C4 alkyl, C3-C4 alkenyl or 2-propynyl group, R2 is a C1-C6 alkyl, cyclopropyl or 1-methylcyclopropyl group, R3, which may be the same or different, is a halogen atom, a C1-C4 alkyl, halogen-substituted C1-C3 alkyl, C1-C4 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.
