Abstract/Contents:"Roughstalk bluegrass (RBG) is a significant weed problem in cool season turf. Studies were conducted during 1999-2001 to determine the effect of fall and/or spring applied fenoxaprop p-ethyl on RBG and the tolerance of other cool-season turfgrasses. In a greenhouse study, fenoxaprop applied at 0.13 to 0.4 kg ha-1 to 'Sabre' RBG 10 weeks after seeding caused significant injury and reduced clipping yields for about 5 weeks which also resulted in a verdure reduction close to 50%. Field studies were conducted on RBG monostands and in cool-season turf naturally or artificially infested with RBG. Results of the field studies had some variation. In general, fenoxaprop at rates of 0.13 to 0.27 kg ha-1 provided fair to good suppression of RBG with repeat applications when applied either in fall, spring, or fall + spring. Best control was observed with fall + spring applications. No suppression of RBG in creeping bentgrass was noted at low rates (0.07 kg ha-1) required for adequate turf safety. Variability in susceptibility to RBG to fenoxaprop may be related to RBG cultivar and environmental conditions. The range of turf species tolerance to fenoxaprop was tall fescue (Festuca arundinacea) > Perennial ryegrass (Lolium perenne) >> Kentucky bluegrass (Poa pratensis) >> creeping bentgrass (Agrostis palustris) and varied with rate, timing, and frequency of application. Fenoxaprop shows significant potential for the suppression of RBG in several cool-season turfgrasses."
