Abstract

SynopsisBracken grows on sites very suitable for forest tree growth allowing a wide choice of tree species. However, the trend in afforestation is towards poorer soils and the area of bracken land being planted is declining. Bracken will damage young trees and methods of its control are reviewed. Hand weeding still has a part to play, but most weeding of heavy bracken growth is by herbicides. Experiments using dicamba, chlorthiamid, picloram and more recently asulam and glyphosate demonstrate a gradual improvement in the selectivity and cost effectiveness of herbicides. Dicamba can only be used before planting and its use is limited to sites where control over three years is assured. Picloram and chlorthiamid at the rates necessary to control bracken are damaging to conifers. Asulam is selective and can be applied after planting giving good control of the bracken. Glyphosate is more damaging to trees than asulam but its use may be justified where a wider spectrum of weed control is required.
