Azolidine derivatives, process for preparing the same and agricultural

Abstract

There are disclosed an azolidine derivative represented by the formula: ##STR1## wherein R.sup.1 represents a hydrogen atom, an alkyl group or a cycloalkyl group; R.sup.2 represents a hydrogen atom, an alkyl group, an alkenyl group, an alkynyl group, an alkoxyalkyl group, an alkenyloxyalkyl group, an alkylthioalkyl group, an alkoxycarbonyl group, a furyl group or a thienyl group, or a phenylalkyl group, a phenoxyalkyl group, a phenylthioalkyl group, a phenylalkyloxyalkyl group, a pyridyloxyalkyl group, a phenoxyphenoxyalkyl group, a benzyloxyphenoxyalkyl group or a pyridyloxyphenoxyalkyl group, or R.sup.1 and R.sup.2 may be combined with each other with carbon atoms bonded thereto to form a group represented by the formula: ##STR2## where R.sup.6 represents a hydrogen atom, a halogen atom or a lower alkyl group; R.sup.7 represents a hydrogen atom, an alkyl group, an alkenyl group, an alkoxy group, an alkenyloxy group or an alkylthio group, or a phenyl group, a phenoxy group, a benzyloxy group or a pyridylthio group; n is an integer of 1 to 3; R.sup.3 represents a hydrogen atom or a lower alkyl group; R.sup.4 represents a hydrogen atom, a lower alkyl group, a phenyl group or a benzyl group; or R.sup.3 and R.sup.4 may be combined with each other with carbon atoms bonded thereto to form a group represented by the formula: ##STR3## where m is an integer of 4 or 5; R.sup.5 represents a hydrogen atom, a lower alkyl group or a phenyl group, or R.sup.4 and R.sup.5 may be combined with each other with carbon atoms bonded thereto to form a group represented by the formula: ##STR4## where l represents an integer of 3 or 4; and Z represents an oxygen atom or a sulfur atom, a process for producing the same and an agricultural and horticultural fungicide containing the same as an active ingredient.
