| Abstract/Contents: | "Fluroxypyr, a broadleaf auxin-type herbicide, was evaluated for weed control effectiveness and turfgrass tolerance. Studies were conducted at the University of Florida West Florida Research and Education center during 2000-2003. Visual control ratings used a 0% to 100% scale, 0%= no control, and 100%= complete control, 70% control was considered minimally acceptable. Turfgrass injury was rated on a 0% to 100% scale, 0%= no visible injury or discoloration and 100%= brown or dead turfgrass, 30% was considered the maximum allowable injury. 'Tifway' and 'TifSport' bermudagrass (Cynodon dactylon X C. transvaalensis), and 'Raleigh' and 'Palmetto' St. Augustinegrass (Stenotaphrum secundatum) in some instances exhibited 10 to 20% injury soon after application. However, both turfgrass species rapidly recovered from any early damage and showed no reduction in quality by four weeks after treatment. Fluroxypyr applied alone at 0.06 to 0.25 lb a.i./A provided inconsistent control of dollarweed (Hydrocotyle sp.). Mixing with clopyralid, MCPP, 2,4-D or metsulfuron improved dollarweed control to at least 85%. Fluroxypyr at 0.28 lb/A provided 90% Virginia buttonweed (Diodia virginiana) control when applied alone. Early control (14 days after application) at lower rates of fluroxypyr was improved with the addition of MCPP but by 40 days after treatment, there was no advantage to having MCPP in the mixture. Sequential applications of fluroxypyr improved late-season control of Virginian buttonweed and spotted spurge (Euphorbia maculata) over single applications. Control improved to 85% or greater with the sequential treatment compare to less than 70% control with the single application. Fluroxypyr appears to offer control of broadleaf weed species in bermudagrass and St. Augustinegrass with minimal turfgrass injury." |
