Journal of Aquatic Plant Management, Volume 45, 2007. Pages 43-46. "Eurasian Watermilfoil and Parrotfeather Control Using Carfentrazone-ethyl" Cody J. Gray, J.D. Madsen, R.M. Wersal and K.D. Getsinger ABSTRACT Two invasive weed species, Eurasian watermilfoil (Myriophyllum spicatum L.)
and parrotfeather [Myriophyllum aquaticum (Vell.) Verdc.], were grown in outdoor
mesocosms to determine the efficacy of carfentrazone-ethyl
(a,2-dichloro-5-[4-(difluoromethyl)-4,5-dihydro-3-methyl-5-oxo-1H-1,2,4-triazol-1-yl]-4-fluorobenzenepropanoic
acid, ethyl ester), alone and in combination with 2,4-D, a herbicide routinely
used for watermilfoil control. Eurasian watermilfoil control was ≥ 98% when
carfentrazone rates were applied alone at ≥ 150 μg ai L-1. |
