NEW MATERIAL:A compound shown by the formula I (X is halogen, nitro, cyano, formyl, lower alkylcarbonyl, etc.; B is -0-, -S-, -SO-, etc.; Y is H, halogen, cyano, cycloalkyl, etc.; m and n are in 0-5, and 0<=m+n<=5; R is phenyl which may be replaced with lower alkyl, or halogen, etc.). EXAMPLE:N-(3,4-Diethoxy-5-methyl-phenyl)-N'-ethoxy-formylamidine. USE:An agricultural and horticultural fungicide, insecticide, and acaricide showing selectively strong fungicidal effects on molds resistant to chemicals and other molds. PREPARATION:A formimidate shown by the formula II (r is lower alkyl) is reacted with an oxyamine shown by the formula RONH2 in a solvent such as methanol, etc., at room temperature-the boiling point of the solvent to give a compound shown by the formula I.
