A method for controlling the growth of aquatic plants in a body of water which is exposed to sunlight comprising depositing on the surface of the body of water over the location where plant life is to be controlled, a benthic barrier which comprises a fabric coated on at least one side with silicone rubber thick enough to prevent root penetration and thin enough to allow gases forming below the barrier to pass through the coating and escape, said silicone rubber comprising crosslinked polyorganosiloxane and filler which blocks the passage of light through the barrier to the bottom of the body of water and raises the specific gravity above 1.0 to a value which allows the barrier to readily settle to the bottom where it covers the aquatic plants or the bottom on which aquatic plant growth is to be prohibited, after the barrier is placed on the water surface, it settles to the bottom and is anchored as necessary to avoid displacement by turbulence in the body of water.
