Pyrimidine compounds of the formula: STR1 in which R1 is alkyl, one of X1, X2, X3 is chlorine or bromine and the two others are respectively --NR1 R2 and --NR3 R4 in which R2 and R3 are, independently of one another, hydrogen, alkyl, cycloalkyl, aryl or aryl substituted by alkyl, hydroxy, chlorine, bromine or STR2 wherein R is hydrogen or alkyl, or form together with the nitrogen atom to which they are linked a nitrogenous heterocyclic radical other than piperazino and substituted piperazino, R4 and R5 are, independently of one another, hydrogen, alkyl, cycloalkyl, aryl or aryl substituted by alkyl, hydroxy, chlorine, bromine or STR3 wherein R is as defined above, or form together with the nitrogen atom to which they are linked a nitrogenous heterocyclic radical other than piperazino and substituted piperazino, at least one of the substituents --NR1 R2, --NR3 R4 being NH2 or STR4 and their salts with mineral or organic acids, are herbicides.
