MOVEMENT OF SELECTED GROWTH-REGULATING CHEMICALS IN ARTIFICIAL GROWING MEDIA
Keyword(s):
The presence of the growth regulators paclobutrazol and uniconazole in leachate or distribution through media consisting of various proportions of Douglas fir bark, sphagnum peat and perlite was evaluated. Distribution through a column 25 cm deep occurred rapidly and growth regulators were found in the leachate the first day after drench application when perlite was in the mix. Movement was limited to a maximum of the top 60% of the column in bark and peat mixes without perlite. Leachate was collected daily over a 12 day period after drenches were applied. Paclobutrazol and uniconazol showed similar distribution patterns in the media.
