Abstract/Contents:"Ventenata is an annual grass weed that is difficult to control especially in hay and grass seed crops including Kentucky bluegrass and timothy. Few grass herbicides are registered for use in Kentucky bluegrass, while none are registered in timothy. Studies were established near Plummer, ID in Kentucky bluegrass and near Potlatch and Gifford, ID in timothy to evaluate weed control and crop injury with various grass herbicides over the growing season. The experimental design was a randomized complete block with four replications and included an untreated check. In Kentucky bluegrass, ethofumesate, pendimethalin, metolachlor, terbacil, pyroxsulam and flufenacet/metribuzin alone or combined with terbacil, primisulfuron, and oxyfluorfen controlled ventenata 74 to 100%. Flufenacet/metribuzin at the high rate injured Kentucky bluegrass 29%, but injury was greatest with pyroxsulam at 80%. In timothy at Potlatch, triasulfuron, sulfosulfuron, terbacil, rimsulfuron, and flufenacet/metribuzin alone or combined with sulfosulfuron or triasulfuron reduced ventenata stand 90% or greater compared to the untreated check. Timothy stand height and seed head formation were reduced 26 to 35% and 10 to 25%, respectively, by rimsulfuron, terbacil and sulfosulfuron at the high rate. At Gifford, ventenata control in timothy was 90% or greater with metolachlor, ethofumesate, diclofop, primisulfuron, oxyfluorfen plus diuron, pyroxsulam, and flufenacet/metribuzin alone or combined with terbacil, flucarbazone, diclofop, aminopyralid, sulfosulfuron, and primisulfuron. Timothy injury was 14 to 21% with flufenacet/metribuzin alone or combined with terbacil, diclofop, sulfosulfuron, and primisulfuron. Dry forage hay weight did not differ among treatments and from the untreated check."
