Abstract

Unrooted cuttings of Lantana ‘New Gold’, Hibiscus ‘White Lephrechaun’, Asian jasmine and Burford holly were propagated under intermittent mist with flats treated with three rates (1/2×, 1× and 2× recommended rates) of oxyfluorfen:pendimethalin (OH2), oxadiazon (Ronstar), oxyfluorfen:oryzalin (Rout), metolachlor (Pennant), pendimethalin (Southern Weedgrass Control), isoxaben:oryzalin (Snapshot), prodiamine (Barricade) and dithiopyr (Dimension). After rooting, cuttings were removed from intermittent mist and grown on as liners. Rooting and liner growth of Hibiscus and Asian jasmine were the most and least herbicide sensitive, respectively. Hibiscus was sensitive to all dithiopyr (Dimension) rates, particularly during liner growth. Sensitivity to herbicides in the propagation of cuttings was dependent on the herbicide, rate and species. Herbicides applied at the recommended rates (1×) controlled all broadleaf and grass weed species evaluated, except for poor yellow woodsorrel control with metolachlor.
