The use of rotenone enables aquatic professionals to eradicate entire populations of undesirabie species of fish from lakes, ponds, reservoirs and streams. Example: over-population of bluegill. 4. Are there any ill effects if I ingest water that was treated with rotenone? The hazard associated with rotenone is very small due to the concentration of rotenone used in the treatment (25-250 ppb or 0.025-0.25 mg/L of water). Studies show lethal doses to humans are 300-500 mg of rotenone/Kg body weight. Put another way, a 160 lb. person would have to ingest 23,000 gallons of treated water at 0.25 mg/L at one sitting to receive a lethal dose. 5. Can I swim in my pond/lake after the treatment? If so, how long after? Yes. You do not want to swim in a rotenone treated body of water until the application has been completed and the pesticide has been thoroughly mixed into the water according to labeling instructions. 6. Who can apply rotenone? The only persons who can legally apply rotenone to any
