Extract

Only a few reports have been published on the susceptibility of rabbitbrush (Chrysothamnus spp.) to chemical herbicides (1, 2, 5, 6, 7). From these publications the following conclusions may be made: (a) 2,4–D (2,4–dichlorophenoxyacetic acid) is more effective on rabbitbrush than 2,4,5–T (2,4,5–trichlorophenoxyacetic acid), (b) June applications are generally best, (c) rabbitbrush is more tolerant to growth regulators than big sagebrush (Artemisia tridentata), and (d) resprouting from the stem base is common.
