Non-native invasive species of aquatic and wetland plants were introduced to waters of the United States as a result of human activities and are causing detrimental effects on beneficial uses (irrigation, fishing, swimming, boating, native flora and fauna) including declines of indigenous aquatic species and aquatic habitat. Selective aquatic weed management is critical to sustaining the function of waters of the United States. The use of diquat dibromide (Reward) as an aquatic herbicide provides significant economic, societal, and environmental benefits due to its unique technical profile and excellent fit within an Integrated Aquatic Weed Management (IAWM) program. Reward is an important tool for aquatic weed control, providing advantages and opportunities for aquatic managers to achieve weed control goals using an environmentally sustainable approach.
