Fluridone（Cat No.:R019963）is a selective herbicide used to control aquatic weeds and algae, particularly in lakes, ponds, and irrigation systems. It works by inhibiting the synthesis of carotenoids, essential pigments in plants that protect chlorophyll from damage. Without carotenoids, plants are unable to photosynthesize properly, leading to their death. Fluridone is effective against a wide range of aquatic species, including hydrilla and other invasive aquatic plants. It is favored for its ability to target specific plants without harming fish or other aquatic life when applied correctly, though care is needed to manage its environmental impact.
