    摘要： Disclosed are pyrimidine derivatives represented by general formula (I) ##STR1## wherein X represents a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, a haloalkyl group or a cyano group; Y.sup.1 represents an alkyl group, a cyanoalkyl group, an alkoxy group, an alkenyl group substituted with a hydroxy group and a halogen atom, an alkynyl group which may be substituted with a hydroxy group, a methylamino group, an alkoxyalkyloxy group, an alkylthioalkyl group or a group of the formula --CH.sub.2 OR.sup.1 where R.sup.1 represents a hydrogen atom, an alkyl group, an alkenyl group or an alkynyl group; Y.sup.2 represents a halogen atom, an alkyl group or a haloalkyl group; R represents a hydrogen atom, an alkyl group, a nitroso group, an alkoxyalkyl group, an alkoxyalkyloxyalkyl group, an alkenyl group, an alkynyl group, a formyl group or an alkylthioalkyl group, with the proviso that (a) when Y.sup.1 represents an alkynyl grop or when Y.sup.1 represents an alkoxy group and Y.sup.2 represents a halogen atom or an alkyl group, X and R are not a hydrogen atom simultaneously, (b) when Y.sup.1 and Y.sup.2 each represents an alkyl group, R is not a hydrogen atom, or (c) when Y.sup.1 represents an alkyl group and Y.sup.2 represents a halogen atom, X and R are not a hydrogen atom simultaneously or X is not a halogen atom nor an alkyl group. Also, agricultural or horticultural compositions containing the pyrimidine derivatives as active ingredient are disclosed, which show high controlling activities for cucumber gray mold (Botrytis cinerea), cucumber downey mildew (Pseudoperonospora cubensis), Alternaria sooty spot of Chineese mustard (Alternaria brassicicola), rice blast (Pyricularia oryzae), etc.
