Use of DRC 1339 to Control Crows in Three Roosts in Kentucky and Arkansas

Field tests utilizing DRC 1339 (3-chloro-4-methylbenzamine hydrochloride) 98% concentrate on whole kernel com for crow (Corvus brachyrhynchos) control were conducted in January and February 1981 in Lexington and Louisville, Kentucky, and in 1982 in Ashdown, Arkansas. Treated bait was placed in staging areas near the roosts after prebaiting indicated good acceptance at the sites. The rate of acceptance varied with bait placement. Best results were obtained when bait was placed on bare ground at habitually used staging areas close to the roost site. Population reductions of up to 25% were obtained with limited baiting. DRC 1339 appears to be a safe, effective toxicant when used on whole corn and bait sites are monitored
