New, non-hygroscopic, crystalline mono-ammonium salts of general formula (I), where, R1 stands for hydroxy or alkyl; -A stands for 1-4 alkyl-amino- or amino-alkyl-groups containing primary or secondary amino-groups, preferably -CH¿2?-NH- or -CH(NH2)-CH2-groups; B stands for ammonium, -ion, or alkyl-substituted ammonium-ion- as well as processes to obtain the same by preparing the mono-ammonium salt of general formula (I), according to any method known generally for the preparation of salts, whereby, along with avoiding other contaminations, on the course of or after salt-formation the di-ammonium salt of general formula (V), where, -R?1¿, A and B stand for the above, is eliminated or its formation is repressed. Herbicidal or plant-growth-regulating compositions containing the non-hygroscopic salts, processes for their preparation and methods of treatment of unwanted plants and weed as well as a composition consisting of a bag, which is solid and preferably flexible in its dry state, which is made of a water-soluble polymer and which contains the new substances or compositions. |
