Abstract

An Evaluation of 10 Herbicides on Cuban bulrush (Oxycaryum cubense (Poeppe & Kunth) Palla) Control Amanda L. Fernandez, and John D. Madsen; Geosystems Research Institute, Mississippi State University, Box 9627 Mississippi State, MS 39762-9627, afernand@gri.msstate.edu Cuban bulrush (Oxycaryum cubense (Poepp & Kunth) Palla) is a floating, epiphytic, perennial, aquatic plant from South America and the West Indies that is sporadically distributed in Florida, Louisiana, southern Georgia, southern Alabama, Mississippi, and coastal Texas. Floating mats of Cuban bulrush impede navigation and recreational use by obstructing shorelines and access areas. It is also highly competitive and has been shown to overtake other aquatic vegetation such as water hyacinth. To date, there are no published studies documenting management techniques for control of Cuban bulrush. The objectives of this study were to determine the efficacy of ten aquatic-labeled herbicides applied at the maximum labeled rate on Cuban bulrush control, and to determine if there is a difference in control between pre-flowering herbicide applications and post flowering herbicide applications. The herbicides tested include glyphosate, carfentrazone, flumioxazin, 2,4-D, triclopyr, imazamox, imazapyr, penoxsulam, byspiribac-sodium, and diquat. Cuban bulrush control was significantly different (p
