Competition as a control for Halogeton glomeratus

Conference ·
OSTI ID:6897782
During the 1978 growing season, preliminary sampling was initiated to determine the effectiveness of perennial vegetation in the control of Halogeton glomeratus, through competition. The study was originated to determine possible alternative methods of control other than spraying with 2,4-D, which eliminates all broad-leaved vegetation on the treated site. Prior studies have indicated that competitive control could be the most beneficial. At the Jim Bridger Mine in southwestern Wyoming, native stands of Artemisia tridentata, Atriplex confertifolia, A. gardneri, and other shrubs adjacent to heavily infected minespoils have successfully prevented the establishment of Halogeton. First year sampling of two minespoil treatments, one with 7.5% cover of native perennials and the other with 1.2% cover of native perennials yielded 199.8 g/m/sup 2/ and 327.4 g/m/sup 2/ of Halogeton (oven dried weight) respectively. Nearby stands of native vegetation had 22.8% cover of shrubs and yielded only trace amounts of Halogeton (attributed to edge effect and the continued trampling of the area by investigators).
