Vj. Anderson et Rm. Thompson, CHEMICAL AND MECHANICAL CONTROL OF FALSE HELLEBORE (VERATRUM-CALIFORNICUM) IN AN ALPINE COMMUNITY, INTercom, (469), 1993, pp. 1
Herbicide and mechanical control treatments for false hellebore (Verat
rum californicum Durand) were applied in the early 1980's at an alpine
site in central Utah. Periodic data collection through 1991 indicated
the treatments' relative effectiveness. The 1991 data also evaluated
natural recovery of the understory plant community. Mechanical treatme
nts were most effective when the rhizome was disrupted; however, the e
nsuing plant communities had a high density of weeds. Several herbicid
es also effectively controlled false hellebore, with fewer weeds in th
e understory afterward.
