    • Plant growth is regulated, e.g., inhibited, by applying to a plant or its habitat a composition containing as an active ingredient a phospholenium salt of the formula ##STR1## in which R.sup.1 is alkyl, substituted alkyl, alkenyl, alkynyl, cycloalkyl, aralkyl, aralkyl substituted in the aryl part, alkoxy, substituted alkoxy, alkylthio or substituted alkylthio,R.sup.2 is alkyl, substituted alkyl, alkenyl, alkynyl, cycloalkyl, aralkyl or aralkyl substituted in the aryl part,Y is a chain of the structure --CH.sub.2 --CH.dbd.CH--CH.sub.2 -- or CH.dbd.CH--CH.sub.2 --CH.sub.2 -- which can be substituted by at least one of halogen and alkyl, andA.sup.- is one equivalent of an anion of a non-phytotoxic acid,In admixture with a solid or liquefied gaseous diluent or carrier or in admixture with a liquid diluent or carrier containing a surface-active agent.
