    摘要: Thiadiazine compounds of the formula (I) ##STR1## wherein R.sup.1 is alkyl, R.sup.2 is alkyl, cycloalkyl, alkenyl or aryl, R.sup.3 is alkyl and R.sup.4 is alkyl, are useful as insecticides. The thiadiazine compounds are prepared by the addition of a dialkylhalothiophosphate to a tetrahydro-6H-1,3,4-thiadiazin-5-one.
