Title: Benthic semi-barrier to control the growth of weeds in aquatic environments

Abstract: A screen of foraminous material is laid directly on the surface of shallow water beds where weed growth is likely or is occurring. The screen is non-reactive to the surrounding water and creates a physical semi-barrier to rootlet and stem formation and to the transmission of light to the area therebetween to thereby retard germination and growth of weeds but not to stop growth entirely. The screen is formed with sufficient openings so that the normal movement of the surrounding water is not materially affected.
