Quaternary ammonioalkanecarboxylic acid anilides as plant growth influencing agents

Abstract

This invention comprises new compounds and a composition for influencing, in particular for inhibiting, plant growth, which contains as active compound at least one quaternary ammonioalkancarboxylic acid anilide of the formula I ##STR1## wherein each of R.sub.1 to R.sub.5 independently represents a hydrogen atom or any indentical or different substituent, each of R.sub.6 to R.sub.8 independently represents an identical or different radical selected from the group consisting of alkyl, substituted alkyl, cycloalkyl, alkenyl, alkynyl, while two alkyl group together with the nitrogen atom can also form a saturated heterocyclic ring or three groups together can form an unsaturated heterocyclic ring a "alkylene" represents a saturated or unsaturated hydrocarbon bridge of 1 to 3 carbon atoms and X represents the anion of a non-phytotoxic acid HX. Method for manufacturing these compounds are described and their use for inhibiting the growth of plants, in particular grass, cereals, soya, vegetables, fruit and ornamentals, for inhibiting the growth of side shoots in tobacco plants and for promoting the ripening and abscission of fruit.
