Abstract/Contents:"Two field studies were conducted near Scottsbluff, NE and Lingle, WY, to determine the response of perennial forage grass to different application timings of propoxycarbazone-sodium and imazapic. The study area was irrigated at both locations. Crested, western and intermediate wheatgrass, green needlegrass, smooth brome, Russian wildrye, sheep fescue, and orchardgrass were planted into wheat stubble in the last week of August 2007. Herbicide treatments for both locations included, propoxycarbazone-sodium(0.06 kg ae/ha) and imazapic (0.105 kg ae/ha) applied 120, 90 and 30 days before planting (DBP), at planting, and 30 days after planting (DAP). Forage grasses were evaluated for injury 30 and 60 DAP. Grass biomass was recorded on May 14, 2008 (Scottsbluff) and June 14, 2008 (Lingle) by harvesting a 0.092 m2 area. No grass injury was observed if treatments were applied 120 DBP. Injury by propoxycarbazone-sodium applied 90 DBP was significant for western wheatgrass and Russian wildrye (11 to 17%). All species were significantly injured by both treatments when herbicides were applied 30 DBP, at planting or 30 DAP. Dry matter production of the majority of the grasses was not affected when treatments were applied either at 30, 90, or 120 DBP at both locations. Sheep fescue planted at Scottsbluff with a 26.5% dry weight reduction was the exception. Visual evaluations done 30 and 60 DAT indicated significant levels of grass injury when propoxycarbazone-sodium and imazapic were applied 30 DBP. The absence of a significant dry weight reduction for this time of application suggest that grasses were capable of recovering from the early injury."
