Zusammenfassung:	NEW MATERIAL:A compound shown by formula I [R is cycloalkyl, cycloalkylalkyl, aryl or arylalkyl (aryl means benzene nucleus, thiophene nucleus, pyridine nucleus or furane nucleus); A is -CO-, -SO2- or OC(=O)-; B is 3-6C alkylene which may be replaced with lower alkyl]. EXAMPLE:2-Cyclohexylsulfonyltetrahydro-1,2-oxazine. USE:An agricultural chemical, an intermediate for preformed chemical mediator, stabilizer, etc. Showing highly controlling effects on blast of rice plant, brown rust of wheat, etc. PREPARATION:An acylhydroxylamine derivative shown by formula II is reacted with a dihalide derivative shown by formula III (X and Y are halogen) in a solvent such as DMF, etc. in the presence of an acid binder (e.g. NaOH) at room temperature - the boiling point of the solvent to give a compound shown by formula I.
