Onaqui Sagebrush Herbcide Subplots

Tebuthiuron (Spike 20P) was applied aerial on the Onaqui herbicide plot to thin the sagebrush and encourage understory growth. This treatment took place in the fall of 2006 after baseline data were collected. Plateau pre-emergence herbicide was crossed with the Spike treatment on half of the subplots to control cheatgrass. The images below show two subplots from 2006-2009, one where Plateau was not used and one where Plateau was sprayed at a rate of 6oz per acre after treatment in fall 2006.
