Abstract

Plant-growth regulating compositions and methods having strong effects on plant growth, containing an aminomethanephosphonic acid composed of the formula ##STR1## in which R is an NH.sub.2 group or an --NH.sup..sym..sub.3 X.sup..crclbar. radical wherein PA1 X.sup..crclbar. is one equivalent of an anion of an organic or inorganic acid, and PA1 R' and R", which may be identical or different, are each alkyl of from 1 to 6 carbon atoms, one equivalent of an alkali metal or alkaline earth metal cation, one equivalent of a protonized nitrogen base or of a compound which contains an N.sup..sym. H.sub.3 group, or hydrogen, provided that R' and R" can simultaneously be hydrogen only if R is an --N.sup..sym. H.sub.3 X.sup..crclbar. radical.
