Comment submitted by Dr. John Alcock

As a professional biologist, I fully support efforts to insure that Rozol and Kaput-D be banned for use in prairie dog control. EPA administrators must know that black-tailed prairie dog populations are a tiny fraction (<1%) of what they once were. To encourage the destruction of these pitiful remnants is disgraceful, particularly since the poisons involved apparently can pass up through the food chain. The EPA should be working on behalf of black-tailed prairie dogs, not against them! Suspend/cancel the registration of Rozol now. Thank you.
