Pocket Gopher Control on Oregon Ponderosa Pine Plantations
Following a series of laboratory bioassays, control of pocket gophers (Thomomys talpoides quadratus) was evaluated on two ponderosa pine (Pimps ponderosa) plantations in Oregon. The forest-land burrow-builder (a bait-dispensing machine) operated satisfactorily in difficult terrain and better than 90 percent control was attained with baits of strychnine alkaloid and Gophacide (O. O-bis [p-chlorophenyl] acctimodoylphosphoramidothioate)
