Jason Ferrell serves as the director of the UF/IFAS Center for Aquatic and Invasive Plants. As the center director, he leads a multidisciplinary group of faculty and staff whose mission is to develop and disseminate strategies for addressing the impact of invasive plants. In addition to this role, Jason also serves as the director of the Pesticide Information Office where he works to ensure that pesticide applicators are trained and licensed in a relevant and timely manner. As a faculty member, Jason has expertise in invasive plant management, pesticide safety and fate of pesticides in the environment.

Working In The Weeds is a podcast by the University of Florida/IFAS Center for Aquatic and Invasive Plants. This podcast will connect scientists with stakeholders, clarify issues surrounding invasive plants, and highlight the research being conducted at the Center.
Emergence patterns of winter and summer annual weeds in Ethiopian mustard (Brassica carinata) cropping systemWeed Science
Ruby Tiwari, et al.
Ethiopian mustard is a biofuel crop recently introduced in the southeastern United States. For this crop to be successful, integrated weed management strategies that complement its rotation with summer cash crops must be developed. The objectives of this research were to evaluate the effect of previous season summer crops on winter weed emergence patterns during Ethiopian mustard growing season and to assess the impact of planting Ethiopian mustard on the emergence patterns of summer weed species.
Effect of carrier volume and application method on waterhyacinth (Eichhornia crassipes) response to 2,4-D, glyphosate, and diquatInvasive Plant Science and Management
Benjamin P. Sperry and Jason A. Ferrell
Mesocosm studies were conducted in 2020 to evaluate the effects of carrier volume and application method on waterhyacinth response to 2,4-D, glyphosate, and diquat. Carrier volumes of 935, 467, and 187 L ha−1 were applied using either a conventional stream, conventional cone, adjustable cone, or a drizzle-stream spray pattern. Reducing carrier volume from 935 L ha−1 reduced spray coverage up to 60%, depending on application method.
Tolerance of rhizoma perennial peanut to glyphosate and triclopyrWeed Technology
Logan J. Martin, et al.
Rhizoma perennial peanut (RPP) is well adapted to the Gulf Coast region of the United States, but its varietal tolerance to glyphosate and triclopyr is not well defined. The research was conducted to determine the effect of various rates of glyphosate and triclopyr on established RPP, and the response of common RPP varieties to these herbicides. The RPP sward was approximately 7 yr younger at Zolfo Springs than at the Ona location.
