Anhydrous ammonia (NH3) was tested as a potential replacement for residual, non specific toxicants as an effective control agent. It was postulated that NH3 would effectively control northern pocket gophers (Thomomys talpoides) and also act as a fertilizer for rangeland vegetation. Compound 1080 was selected as a standard for comparison of gopher control efficiency. Over 700 burrow systems were treated or monitored. Results showed compound 1080 to be 81 percent and NH3 45 percent efficient in controlling gophers. Although fertilizing effects of NH3 were positive, the low control efficiency and high application costs make NH3 an unlikely replacement for the now restricted residual toxicants.
