MULTIFLORA ROSE (Rosa multiflora) CONTROL USING FERTILIZER IMPREGNATED METSULFURON-METHYL D. Richmond, E. Smolder, M. B. Benoett, D. Davis, C. Hickman, J. Hileman, E. Rayburn, and R. Chandran' ABSTRACT Multiflorarose (Rosa multiflora L.), an introducedspecies, is a widespreadweed problem in West Virginia. Past studies showed that fertilizer impregnated metsulfuronwas effective in controllingthis weed. In 1999, six field studies were conductedin differentcounties to determinethe effectiveness of metsulfuron impregnated in a 19-19-19 fertilizer. Metsulfuron (45 or 90 mg) dissolved in 100 ml water, each of which impregnated in 50 g fertilizer, provided >90% control of the weed at four locations at 12 weeks after treatment (WAT). Average visual injury fromthe lower ratewas 92%andthatfromthe higherratewas 97% at 12 WAT. At fourlocations, therewere no differencesin injuryratingsat 12 WAT fromherbicide rates.At 8 WAT,
