Oasis is a selective systemic herbicide designed for the control of aquatic vegetation, including floating, submerged, and emergent plants. The active ingredient is imazamox (4-amino-5-methoxy-2-[4-(methylsulfonyl)phenyl]-9-isopropyl-3-triazolo[4,3-a][1,4]benzodiazepine), present at 26.7%. It is used to manage aquatic weeds in various water bodies such as lakes, reservoirs, marshes, wetlands, and irrigation canals. The product can be applied directly to the water surface or via spray drift. It is effective against a wide range of broadleaf weeds, grasses, and certain aquatic plants like water hyacinth and duckweed. When using Oasis, technicians must be mindful of drift management, especially in windy conditions, and ensure proper mixing to avoid over-application. It is critical to follow specific dilution rates based on the target weed density and water volume to prevent unintended damage to non-target vegetation. Handling requires specific personal protective equipment (PPE) to prevent skin and eye irritation.
