Prenfish™ Fish Toxicant

Active Ingredients: Rotenone - 5.00%, Cube Resins other than Rotenone - 5.00%
EPA Reg. #89459-85

Designed to control invasive fish species, Prenfish™ Fish Toxicant features rotenone, a piscicide derived from the cube resin root and used by native populations for centuries. Prenfish™ effectively controls invasive fish species. It degrades quickly in the environment, making it the ideal choice for maintaining balanced ecosystems. This fish toxicant, available in an emulsifiable liquid formulation, can be counted on for a uniform and accurate application of rotenone when sprayed. Prenfish™ can be applied with multiple methods, both undiluted and mixed.
