Cana subspecies cana) and <br />Wyoming big sagebrush (A. ttidentata <br />subspecies wyomingensi s). Use ultraviolet <br />lamp for identification. Proper grazing <br />management is essential as heavy grazing will <br />lead to even heavier stands of sagebrush. <br />Fringed sagebrush: soil moisture arri timing <br />is critical with phenoxy herbicides. Spray <br />when new growth is 2 inches (5 cm) or more. <br />Spraying operations should be made when Sand <br />sagebrush is growing rapidly and 6 to 3 inches <br />(15 to 20 cm) of new twig growth is evident. <br />These conditions generally occur from May IS <br />to June 20. Sufficient moisture must be <br />present to insure continued plant growth. <br />Sand sagebrush may resptout and a repeat <br />spraying may be necessary. Defet grazing <br />through the growing season in year that it is <br />sprayed. <br />• <br />• <br />
