The present invention is an aqueous composition for controlling or eradicating moss from undesirable locations such as lawns and golf course putting greens. The composition contains a fertilizer, a metal containing salt, a surfactant or wetting agent, and optionally, an acidic pH control agent. The composition can be provided in a form to be mixed and/or diluted by the end-user or in an aqueous form ready to be sprayed onto the infected area. Since the product can be broadly applied and encourages grass growth and development, it provides significant advantages over conventional moss control products intended for spot treating only.
