Gary Philpotts, Roundup lawn and Garden UK business director said:
"In order to capitalise on the surge in demand for weedkillers that we are witnessing, it is vital that retailers respond to market demand and give this category the on shelf and key promotional space it clearly deserves. It is also important that the most prominent positioning is given to the brands that consumers want to purchase."
