    Description

    Practical brush control appears to be within sight for some of the problem areas in central Oregon as a result of experiments conducted on the Pringle Falls Experimental Forest and Deschutes National Forest. Small-plot trials to determine which chemicals will kill manzanita (Arctostaphylos parryana var. pinetorum (Rollins) Wiesl. & Schrieb.) and snowbrush (Ceanothus velutinus Doug.), and at what season, were made in 1953 using a hand sprayer. In 1954, the hand-sprayer tests were continued with a few of the more promising chemicals,and aerial application was tried on a pilot-plant scale.
