Gophacide, a Candidate for Control of Ord's Kangaroo Rat

Kangaroo rat foraging in proximity to a colony of reintroduced black-tailed prairie dogs

“…Much like prairie dogs, kangaroo rats were once viewed as pests having a deleterious impact on the condition of the rangelands, and were oftentimes exterminated (Vorhies and Taylor, 1922;Wood, 1965;Schroeder, 1967;Whitford, 2002). In recent years the desertification due to drought and non-existent or poor livestock grazing management has been exacerbated in part due to the seed caching activities of kangaroo rats, which can promote shrub encroachment (Duval et al, 2005;Kerley and Whitford, 2009;Eldridge et al, 2009).…”

Laboratory evaluation of gophacide as a rodenticide for use against Rattus norvegicus and Mus musculus

“…Ward, Hegdal, Richens & Tietjen (1967) and Richens (1967) describe laboratory and field work with pocket gophers (Thomomys, Geomys and Cratogeomys spp. ), and Schroeder (1967) with Ord's kangaroo rat (Dipodomys ordii). In all these cases gophacide used in the field was laid in, or at the entrance to burrow systems, and found to be effective.…”
