Abstract

Three years' experience in spraying regrowth of chamise-sage brush types has shown that broadcast chemical spraying by either tractor boom or helicopter is effective. On some of the FUEL-BREAK demonstration and action projects, a single application of hormone type chemicals has killed almost all of the brush sprouts and seedlings, so that the remaining plants could be easily killed by hand spraying. On other projects a second broadcast application was needed to reduce the number of sprouting plants to the point where they could be controlled by hand spraying. This degree of control from two broadcast applications is generally considered satisfactory. But we still hope to learn how to kill almost all chamise sprouts with one broadcast spraying.
