Effect of Fungicide Drenches on Root Initiation by Geranium Cuttings. G. W. Moorman, Assistant Professor, Suburban Experiment Station, University of Massachusetts, Waltham 02254. W. C. Woodbridge, Research Assistant, Suburban Experiment Station, University of Massachusetts, Waltham 02254. Plant Dis. 67:612-613. Accepted for publication 22 October 1982. Copyright 1983 American Phytopathological Society. DOI: 10.1094/PD-67-612.

Cuttings of Yours Truly and Easham cultivars of zonal geraniums (Pelargonium hortorum) and Dark Pink, a cultivar of ivy geranium (Pelargonium peltatum), were rooted in peat and perlite (1:1, v/v) that had been treated with six commercially available fungicides alone and in combinations and compared with cuttings rooted in untreated mix. In general, the fungicides tested neither enhanced nor inhibited root initiation. Caution is urged in extrapolating these results to other media, plant materials, seedling production, other fungicides, and different timing of application.
