“…In other studies, 2,4-D, dicamba, and clopyralid have provided 80% or more control of rabbitbrush (Cluff et al 1983;Mohan 1973;Whisenant 1988). Achieving this level of control requires applying herbicides when plants are actively growing, usually indicated by 6 to 10 cm of new leader growth (Hyder et al 1958;Mohan 1973). It has also been suggested that soil moisture should be high enough to allow rapid growth (Mohan 1973).…”

The objective of this study was to test the potential for using a single-entry procedure to revegetate Russian knapweed– and green rabbitbrush–infested rangeland. I hypothesized that simultaneously applying an herbicide and seeding in the fall would produce the highest establishment and growth of desired species. For Russian knapweed, treatments included three seeding rates (zero, low, and high) and two herbicides (with and without clopyralid plus 2,4-D) applied in either the spring (2003) or fall (2004). The seed mixture included pubescent wheatgrass, Siberian wheatgrass, and alfalfa. Grasses were seeded on October 21, 2003 (fall dormant), and April 5, 2004 (spring), using a no-till rangeland drill. The seeding rates consisted of 3.4, 6.8, and 9.3 (low) or 5.0, 9.0, and 12.3 (high) kg ha−1of alfalfa, Siberian wheatgrass, and pubescent wheatgrass, respectively. For green rabbitbrush, treatments included two seeding levels (13.5 kg ha−1of Siberian wheatgrass and not seeded) and three herbicides (clopyralid, dicamba, and 2,4-D) and a control applied in July. Clopyralid plus 2,4-D (0.21 plus 1.12 kg ha−1) and dicamba at 2.1 kg ha−1gave 61 and 66% control of Russian knapweed and green rabbitbrush, respectively. Herbicides interacted with seeding to provide the highest density of seeded species on the Russian knapweed site. These data support the hypothesis that simultaneously applying an herbicide and seeding in the fall would produce the highest establishment and growth of desired species. Conversely, only seeding affected Siberian wheatgrass establishment on the rabbitbrush sites. It may be reasonable to seed Siberian wheatgrass without controlling rabbitbrush if forage production is the primary objective.

“…For other species of rabbitbrush growing on upland sites, the end of the period of susceptibility to 2,4 -D is clearly delineated because of a decrease in availability of soil moisture for plant growth (7). In the environment in which salt rabbitbrush and greasewood grow, moisture is probably not limiting until late in the season; therefore, growth of salt rabbitbrush and its susceptibility to 2,4 -0, although reduced at later spray dates, extend well into the summer.…”

“…Most species of rabbitbrush can be controlled with 2,4 -D if applied at the optimum stage of shrub susceptibility (7). The best date for herbicide application is predicted by re-1ating the stage of development of the current year's shoot growth to the availability of soil moisture and temperatures favorable for active plant growth and translocation.…”

Herbicidal Control of Greasewood (Sarcobatus vermiculatus) and Salt Rabbitbrush (Chrysothamnus nauseosusssp.consimilis)

et al. 1983

The control of greasewood [Sarcobatus vermiculatus(Hook.) Torr.] and salt rabbitbrush [Chrysothamnus nauseosusssp.consimilis(Greene) Hall and Clem.] was investigated with application of 2,4-D [(2,4-dichlorophenoxy)acetic acid] and a mixture of 2,4-D and picloram (4-amino-3,5,6-trichloropicolinic acid). The herbicides were applied at 2-week intervals from May 1 to August 1. Greasewood had accelerated shoot growth and was most susceptible to application of 2,4-D during June. Accelerated shoot growth and maximum susceptibility to 2,4-D of salt rabbitbrush began in June and extended into July. Mortality of greasewood and salt rabbitbrush from 2,4-D at 2.2 kg/ha applied at optimum dates averaged 72 and 87%, respectively. The picloram/2,4-D mixture was more effective for greasewood control than 2,4-D alone in 1 yr at very early and late application dates on a xeric site and only at the last date of application on a mesic site. Reapplication of 2,4-D at 2.2 and 3.3 kg/ha in June to partially controlled stands gave excellent control of both greasewood and rabbitbrush.
