Evaluation of the herbicide 'Roundup' ® for control of bitou bush (Chrysanthemoides monilifera).
C. monilifera is a vigorous shrub introduced for sand stabilization and revegetation of mined lands which threatens the native coastal vegetation in New South Wales, including the coastal rainforest. In trials at two sites using various concentrations of Roundup [glyphosate] satisfactory short-term control was achieved at concentrations of 0.5-1%, depending on the amount of foliage that could be covered. Some damage was caused to native species, particularly Acacia saligna, but this was considered acceptable. Repeated spraying would be necessary to control newly germinated seedlings under killed bushes.
