Management Information When R. communis becomes weedy in neglected cropland and pasture it is matter of controling the invasive through cultivation and mowing (Francis, UNDATED), but in more difficult or sensitive environments Tunison and Zimmer (UNDATED) suggest cutting the stump of mature R. communis and applying the herbicide "Banvel" along with the mechanical control techniques of uprooting seedling. The authors report that Banvel was nearly 100% effective. Langeland and Stocker (UNDATED) also suggest treating R. communis with either basal bark or cut-stump methods followed by an application with 10% Garlon 4, but the authors reiterate that the site must be revisited several times after the initial herbicide treatment to hand pull seedlings that sprout.                Location Specific Management Information Galapagos Islands Please follow this link Rentería et al 2006 to an illustrated guide providing practical information for the effective control of the worst invasive plant species in Galapagos.
