Control bracken Farmland Conservation

A systematic review of methods to control bracken (Stewart et al. 2005) found that the herbicide asulam reduces bracken abundance but regeneration can be rapid and multiple applications are necessary. Complete eradication has not been demonstrated. Available evidence suggests cutting may be as effective as asulam application, particularly if there are two cuts in the same growing season. Further research is needed to compare the effectiveness of different ways of applying asulam and to compare cutting and asulam. There was not robust experimental evidence on the effectiveness of rolling, burning or grazing to control bracken. The review examined the effectiveness of using the herbicide asulam, cutting, hand-pulling, rolling, livestock grazing and burning to control bracken.
