Abstract/Contents:"The exotic weed, Japanese stiltgrass, (Microstegium vimineum), is becoming a common invasive annual grass in fine and rough turf in the northeastern United States. Fluazifop controls several annual weed grasses and has limited turf tolerance on some perennial grass species. Applications of broadleaf weed control herbicides and turf growth regulators using a thin invert emulsion and special nozzles that produce small uniform spray droplets have been effective at spray volumes of 5 gal/A or less. This system was used to apply fluazifop to a dense stand of stiltgrass, smooth crabgrass (Digitaria ischaemum), and nimblewill (Muhlenbergia schreberi) in a mixed creeping red fescue (Festuca rubra) and bluegrass (Poa pratensis) turf. Application was made on July 5, 2003, with a backpack sprayer equipped with a specially designed ultra low volume nozzle using a thin invert emulsion as a carrier to apply fluazifop at 0.25 lb/A in a total spray volume of 5 gal/A. Evaluation 30 DAT showed the following percent injury to the target annual grasses and the fescue and bluegrass turf: Japanese stiltgrass (60%), smooth crabgrass (95%), nimblewill (10%), red fescue (10%), and bluegrass (60%). Evaluation 90 DAT showed total recovery of red fescue, partial recovery of bluegrass, total control of crabgrass, and no control of nimblewill. Stiltgrass partially recovered, but did not set seed before frost. ULV treatment using a thin invert emulsion as a carrier was effective in suppressing growth and regrowth of stiltgrass with little injury to red fescue. The treatment injured bluegrass severely. Future ULV trials will use grass control herbicides that have shown greater turfgrass tolerance."
