Abstract

Late season termination of reproductive plant growth of a plant having an indeterminate growth pattern is achieved by the application of a semicarbazone plant growth regulator to a locus of a growing plant at a time following peak bloom of the plant. The semicarbazone is applied as an active ingredient in an amount sufficient to terminate continued reproductive growth of the plant without substantially affecting mature reproductive growth existing on the plant at the time of application. Most preferably, the semicarbazone is diflufenzopyr.
