  • Toxicokinetics and coagulopathy threshold of the rodenticide diphacinone in eastern screech‐owls (Megascops asio)

    In the United States, new regulations on second‐generation anticoagulant rodenticides will likely be offset by expanded use of first‐generation anticoagulant rodenticides. In the present study, eastern screech‐owls (Megascops asio) were fed 10 µg diphacinone/g wet weight food for 7 d, and recovery was monitored over a 21‐d postexposure period. By day 3 of exposure, diphacinone (DPN) was ...

  • Chlorophacinone residues in mammalian prey at a black‐tailed prairie dog colony

    Black‐tailed prairie dogs (BTPDs), Cynomys ludovicianus, are an important prey for raptors; therefore, the use of the rodenticide Rozol (0.005% chlorophacinone active ingredient) to control BTPDs raises concern for secondary poisonings resulting from the consumption of contaminated prey by raptors. We observed Rozol exposure and adverse effects to mammalian prey on 11 of 12 search days of the ...

  • CYP‐mediated warfarin metabolic ability is not a critical determinant of warfarin sensitivity in avian species; in vitro assays in several birds and in vivo assays in chicken

    Coumarin derivative anticoagulant rodenticides used for rodent control are posing a serious risk to wild bird populations. For warfarin (WF) a classic coumarin derivative, chicken have a high LD50 while mammalian species generally have much lower LD50. Large interspecies differences in sensitivity to WF are to be expected. We previously reported substantial differences in WF metabolism among ...

  • The Adequacy of FIFRA to Regulate Nanotechnology-Based Pesticides

    As applied to pesticides, the new and developing area of nanotechnology has the potential to bring real benefits, but also regulatory challenges. Reportedly, it has already begun changing the nature of some pesticides. There are consumer products on the market today using engineered nanoparticles of active ingredients such as silver to achieve antimicrobial effects, and many more are likely. Even ...

  • EPA clarifies position on ion-generating equipment

    Certain washing machine manufacturers probably didn't think they needed to register their products as pesticides when designing and making them. However, this is exactly what they'll be required to do under 72 Fed. Reg. 54039, which the U.S. Environmental Protection Agency (EPA) clarified on September 21. Washing machines using silver electrodes to produce silver ions to kill germs are considered ...
