Bromadiolone is a second generation anticoagulant that is currently registered as a toxicant controlling commensal rodents. This laboratory study was conducted to provide us with preliminary information on the effectiveness and secondary hazards of bromadiolone as a prairie dog (Cynomys spp.) toxicant. We planned to use this information to decide on the appropriateness of pursuing field research projects using this compound. For an overview on bromadio-lone, see Poche (1986). This was the second laboratory study we conducted on alternative prairie dog toxicants. The first, on chlorophacinone, was reported earlier (Fisher and Timm 1988). Our desire was not to directly com-pare the effectiveness of bromadiolone to chlorophacinone, but to determine if we could find a safe and effective bait formula-tion that could be tested later in the field.
