An agricultural and horticultural fungicidal composition comprising a benzothiazole derivative represented by formula (I): <CHEM> wherein R1 represents a lower alkyl group, an alkenyl group, an alkynyl group, a cycloalkyl group, an alkoxyalkyl group, a benzyl group, an alkyl group containing a carbonyl group or an alkoxyalkyl group containing a carbonyl group; and R2 represents a lower alkyl group, an alkoxy group or an alkyl group having from 1 to 3 carbon atoms and containing from 1 to 6 fluorine atoms, and a compound having a fungicidal activity is disclosed. The composition exhibits a markedly improved effect as compared to the effects of the individual use of the ingredient and is useful as the agricultural and horticultural fungicidal composition as it exhibits preventive and curing effects on plant diseases.
