Bracken fern has been responsible for suppression of growth in radiata pine plantations in the south-east of South Australia. Trials showed that best control is achieved by autumn applications of herbicides to dense stands of mature healthy fronds. In general, glyphosate was more effective than asulam, hexazinone, chlorsulfuron or metsulfuron-methyl. All warrant further research on factors affecting efficacy. Adjuvants such as diesel plus emulsifier, Ulvapron and particularly Silwet enhanced the herbicide effect on mature fronds. The recommended treatment for operational use is an autumn application prior to planting of glyphosate at 3.24 kg per ha a.i. plus Silwet at 0.25 percent vv. This has provided effective control for up to 4 and a half years.
