Abstract

The impact of annual preemergence herbicide usage on the rooting potential of seven commercially important woody ornamental species was studied. Granular formulations of dichlobenil (2,6-dichlorobenzonitrile), diphenamid (N,N-dimethyl-2,2-diphenylacetamide), simazine [2-chloro-4,6-bis(ethylamino)-s-triazine], and trifluralin (α,α,α-trifluoro-2,6-dinitro-N,N-dipropyl-p-toluidine] employed as dormant season or spring applications had no inhibitory effects on the rooting of plants following transplantation. Season of transplanting influenced subsequent root growth of Japanese holly (Ilex crenata Thunb. var. convexa Makimo), Rosebud azalea (Rhododendron X ‘Rosebud’), and Hicks' yew (Taxus media Rehd. var. hicksii Rehd.) more than herbicide treatment. Hardwood cuttings taken from plants grown in herbicide-treated soil rooted as well as those from untreated controls. Plants grown in full sunlight or 55% shade exhibited similar root growth and insensitivity to preemergence herbicides.
