Daniel S. Sullivan, Monty. Sullins, Montana. · 1987
The efficacy of a paraffinized diphacinone (50 ppm) grain bait formed in 113 g blocks and a strychnine (500 ppm) hulled oat bait was tested on the northern pocket gopher.Bait was applied under field conditions by hand methods.The diphacinone bait blocks averaged 70.7 percent reduction in gopher activity 28 days after application.The strychnine bait averaged 78.4 percent reduction in gopher activity during the same period.
