Methoxyiminoacetic acid derivative and agricultural/horticultural fungicide containing the same as active ingredient

Abstract

A methoxyiminoacetic acid derivative represented by the following formula (I): ##STR1## wherein X represents a hydrogen atom, a halogen atom, an alkyl group having 1 to 4 carbon atoms or an alkoxy group having 1 to 4 carbon atoms; A represents a methoxy group or a methylamino group; when A is a methoxy group, B represents --O--CO-- or --N=C(R.sup.1)-- and when A is a methylamino group, B represents --O--CR.sup.1 R.sup.2 --, wherein R.sup.1 and R.sup.2 independently represent a hydrogen atom, an alkyl group having 1 to 4 carbon atoms or a trifluoromethyl group; and Ar represents an optionally substituted aryl group or an optionally substituted heteroaryl group, and an agricultural/horticultural fungicide containing the same as an active ingredient.

Dependencies are inferred from the claim text.
