Born in Hendersonville, North Carolina, Robert Morgan grew up on his family’s farm and wrote his first short story in the sixth grade at the prompting of a teacher. During college, after a professor said reading one of Morgan’s stories moved him to tears, Morgan transferred from North Carolina State University, where he was studying mathematics and engineering, to the University of North Carolina at Chapel Hill, majoring in English. He began encouraging young writers himself when he accepted a teaching position at Cornell University in 1971. Since then, Morgan has made his academic home at Cornell in Ithaca, New York, on the northern edge of Appalachia, but his creative home is the southern mountains of his boyhood and young adult years....

Abstract Additional active ingredients are needed for use in aquatic systems in order to respond to new threats or treatment scenarios, enhance selectivity, reduce use rates, and to mitigate the risk of herbicide-resistance. Florpyrauxifen-benzyl is a new synthetic auxin developed for use as an aquatic herbicide. A study was conducted at North Carolina State University, in which 10 µg L−1 of 25% radiolabeled florpyrauxifen-benzyl was applied to the isolated shoot tissue of ten different aquatic plant species in order to elucidate absorption and translocation patterns in these species. Extremely high levels of shoot absorption were observed for all species and uptake was rapid. Highest shoot absorptions were observed for crested floatingheart [Nymphoides cristata (Roxb.) Kuntze] (A192 =20 µg g−1), dioecious hydrilla [Hydrilla verticillata (L.f.) Royle] (A192 =25.3 µg g−1), variable watermilfoil (Myriophyllum heterophylum Michx.) (A192 =40.1 µg g−1) and Eurasian watermilfoil (Myriophyllum spicatum L.) (A192 =25.3 µg g−1). Evidence of translocation was observed in all rooted species tested with the greatest translocation observed in N. cristata (1.28 µg g-1 at 192 HAT). The results of this study add to the growing body of knowledge surrounding the behavior of this newly registered herbicide within aquatic plants.
