Water primrose: Combination treatment using herbicides and physical removal
A study in 1996-2001 in the Botany Wetlands, Australia (Chandrasena et al. 2002) found that using a combination of herbicide application and physical removal, and other actions such as promotion of native plants and mulching, reduced the infestation of Peruvian primrose-willow Ludwigia peruviana by 85-90%. The cover of indigenous perennial plants increased. This was facilitated by ‘capping’ select areas of slushy mud with additional soil suitable for plant growth. Herbicide application on single-species stands was based on 1.0% ‘Bi-active’ glyphosate, but for mixed stands containing desirable plants 0.6% 2,4-D amine was applied. Each year, dead weed stands were mechanically cleared and burned to remove risk of regrowth. To control Peruvian primrose-willow seedling flushes, leaf and bark mulch was added to areas cleared of water primrose, and the water level of upstream ponds was managed.
