摘要:
An agricultural-horticultural fungicide composition comprising a 5H-1,3,4-thiadiazolo[3,2-a]pyrimidin-5-one derivative represented by the general formula wherein X is a hydrogen atom, a halogen atom, a lower alkyl group or a lower alkoxycarbonyl group; Y is a hydrogen atom, a lower alkyl group or a phenyl group; and R is a linear or branched alkyl group, a benzyl group, a mono- or dimethylbenzyl group or a phenethyl group; with a proviso that when Y is a hydrogen atom, or R is a mono- or dimethylbenzyl group, X is a lower alkoxycarbonyl group.
