Three experiments were conducted at a site near Sheridan, WY to compare imazapic, with and without pendimethalin to oryzalin for their influence on weed control, establishment, germination, and injury of Lewis blue flaz [Linum lewisii (Pursh.) var lewisii ], Indian blanket flower (Gaillardia aristata (Pursh.)], Rocky Mountain penstemon [Penstemon strictus (Benth.)], purple prairieclover (Dalea purpurea (Vent.) var purpurea ), purple prairie coneflower [Echinacea angustifolia (DC.) var angustifolia ], white yarrow [Achillea millefolium (L.)],upright prairie coneflower [Ratibida columnifera (Nutt.) Woot. & Standl.], thickspike wheatgrass [Elymus macrourus (Turcz.) Tzvelev. var `Critana'], western wheatgrass [Pascopyrum smithii (Rydb.) A. Love var `Rosana'], and big bluegrass [Poa secunda (J. Presl.) var `Sherman']. Herbicide mixtures applied before plant emergence included imazapic at 0.03 kg ai/ha, 0.07 kg ai/ha, and 0.1 kg ai/ha, imazapic at 0.07 kg ai/ha tankmixed with pendimethalin at 0.55 kg ai/ha, oryzalin at 0.55 kg ai/ha, and oryzalin at 0.82 kg ai/ha. Plant establishment, as indicated by plant count density one month and twelve months after planting, was imporved [improved] when treated with imazapic in weedy environments. Six of the seven tested wildflowers and the three grasses tested showed tolerance to imazapic applied pre-emergence. Based on the findings in this study, purple prairieclover, Indian blanketflower, and Lewis blue flax, when seeded with Rosana western wheatgrass, have the potential for road-side establishment in Wyoming when treated with imazapic at 0.07 kg ai/ha or 0.1 kg ai/ha."
