Chemical Control of Low Sagebrush and Associated Green Rabbitbrush

Abstract

Low sagebrush species were effectively controlled with low volatile esters of 2,4-D at 2 lb/acre applied from May 1 to May 15 on sites with early phenology and May 15 to June 1 on sites with late phenology. Sandberg bluegrass phenology ranged from late boot to fully headed but preanthesis. Green rabbitbrush in mixed stands with low sagebrush was effectively controlled with 2,4-D at 3 lb/acre applied near the end of the treatment period for low sagebrush. A combination of picloram plus 2,4-D was also evaluated for green rabbitbrush control.
