US to OK new prairie dog rodenticide
The US EPA has proposed a one-year approval for Scimetrics’ rodenticide, Kaput D Prairie Dog Bait (diphacinone), for the control of black-tailed prairie dogs in ten states. Apart from the active ingredient, the proposed label is essentially identical to that of LiphaTech’s Rozol Prairie Dog Bait (chlorophacinone), the EPA notes. The labels are worded such that either but not both ais could be used against prairie dogs in a particular season. Earlier this year, the Agency restricted the use of Rozol to protect endangered species in six states ( Agrow No 638, p 19).
