Water primrose: Chemical control using herbicides
A before-and-after field study conducted from 2006 to 2007 in the UK (Centre for Ecology and Hydrology 2007) found that the herbicide glyphosate combined with a non-oil soya sticking agent, reduced the abundance of creeping water primrose Ludwigia peploides. After 56 days, the biomass of creeping water primrose was reduced by over 97% compared with the biomass before treatment. When glyphosate was combined with TopFilm, it reportedly killed the plant. A solution of 360g/litre of glyphosate (Roundup Pro Biactive) was applied at a rate of 6 litres/ha and the non-oil soya sticking agent was applied at a rate of 450 ml/ha. Further details of the experimental treatments, such as area treated, are not provided.
