Pyrimidine compounds of the formula: ##STR1## in which R.sub.1 is alkyl, one of X.sub.1, X.sub.2, X.sub.3 is chlorine or bromine and the two others are respectively --NR.sub.1 R.sub.2 and --NR.sub.3 R.sub.4 in which R.sub.2 and R.sub.3 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, R.sub.4 and R.sub.5 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 --NR.sub.1 R.sub.2, --NR.sub.3 R.sub.4 being NH.sub.2 or ##STR4## and their salts with mineral or organic acids, are herbicides.

2-(Or4-)amino-5-alkylthio-pyrimidine herbicides

Phosphorus-containing flame proofing mixtures with low crystallization temperatures and with the ability significantly to improve the flame resistance of materials without adversely affecting the other properties of the materials, the mixtures being principally comprised of phosphonates having the structure: ##STR1## wherein X is chloro or bromo; Z.sub.1, Z.sub.2 and Z.sub.3 are the same or different and are --CH.sub.2 --CH.sub.2 -- or ##STR2## and R is CH.sub.3 or CH.sub.2 Cl, and the molar ratio of the --CH.sub.2 --CH.sub.2 --X groups to the total of --CH.sub.2 --CH.sub.2 --X and the --CH.sub.2 --CHR--X groups is from 2 to 90%, these flame proofing mixtures being usable with both synthetic and natural materials, together with the flame-resistive natural and synthetic materials so made.

Phosphorus-containing flame proofing compositions for synthetic materials

A process for destroying weeds in sorghum crops which comprises applying to the area of the growing crop or to the crop area before the crop emerges, 2,4-diamino-6-chloro-5-methylthio-pyrimidine or a mixture of the two isomeric compounds 2,4-diamino-6-chloro-5-methylthio-pyrimidine and 4,6-diamino-2-chloro-5-methylthio-pyrimidine in which 2,4-diamino-6-chloro-5-methylthio-pyrimidine is preponderant, the rate of application of the above compound or mixture being from 300 g/ha to 4,500 g/ha. Herbicides may be simultaneously applied.

Process for the herbicidal treatment of sorghum using
