The invention relates to novel 2,4-diamino-5-alkylsulfinyl- or -alkylsulfonyl-6-halopyrimidines of the formula STR1 wherein n is 1 or 2, R1 is C1 -C4 alkyl, each of R2 and R3 is hydrogen, C1 -C6 alkyl or C3 -C6 cycloalkyl and X is chlorine, bromine or fluorine. These compounds have selective herbicidal action and inhibit plant growth. They are obtained by amination of halogen-substituted or hydroxyl-substituted amino-5-alkylsulfinyl- and -sulfonylpyrimidines. The invention also relates to the production of 5-sulfinylpyrimidine intermediates.
