Abstract

An outdoor mesocosm system was used to evaluate the growth regulator flurprimidol (trifluoromethoxy)phenyl]-5-pyrimidine-methaanol]) as a potential management tool on hydrilla (Hydrilla verticillata (L. f. ) Royle) and American pondweed (Potamogeton nodosus Poiret). Treatments included single doses of flurprimidol at 100 and 200 mu g/L, a split application of 100 mu g/L, and untreated controls. Increasing contact time by applying a split treatment of flurprimidol was more effective forsuppressing plant growth than applying flurprimidol as a single dose. The split application reduced shoot length and biomass by 69 and 50%,respectively, for hydrilla, and 34 and 86%, respectively, for American pondweed, at 12 weeks after treatment (WAT). Flurprimidol-inhibited American pondweed shoots had 84% lower total nonstructural carbohydrates (TNC) than untreated plants at 6 WAT, whereas hydrilla had 80% lessshoot TNC at 12 WAT. This information will be useful for assessing the susceptibility of target and nontarget aquatic plants to flurprimidol.
