Bracken (Pteridium esculentum) was effectively controlled for 2.5 years using metsulfuron methyl with and without the addition of glyphosate, applied by a wiper. Wiper application gave more immediate control and there was less regrowth at the end of the experiment compared with sprayed treatments. A mixture of metsulfuron methyl and glyphosate applied through a wiper gave the best results, with up to 95% bracken control. Further investigations of wiper application using a mixture of metsulfuron methyl and glyphosate at seven sites around Tasmania, gave greater than 85% control of bracken when assessed 10 months after application. Results show that only a single pass with a carpet type wiper is required for bracken control. Control of bracken was achieved with applications from January through to May (mid summer through till autumn).
