Hydrilla (Hydrilla verticillata) is a nonindigenous aquatic nuisance submersed plant with two biotypes that have historically spread across the United States. Recently, a third biotype of hydrilla has been characterized in the Connecticut River. There is very little published information available about this biotype. Research will be conducted to document important biological and phenological characteristics of the CR biotype. Results from these studies will document important factors in the growth and reproduction of the CR biotype that may be used to determine potential invasiveness of this biotype in comparison to the two biotypes commonly found in the US.
USACE has need for assistance with multiple field and mesocosm projects during 2020-22 exists per herbicide applications to evaluate treatment efficacy on invasive plants, impacts on non-target vegetation, and fate/dissipation of aqueous herbicide residues under a variety of conditions. This agreement will fund 50% of a NCSU employee to assist USACE with research needs.
Like other areas of weed management, herbicide applications for aquatic weed control are exclusively conducted via manned application systems. Whether by boat, land-based vehicle, or aircraft, aquatic herbicide operations are time and labor-intensive. Interest in utilization of unmanned aerial vehicles (UAS) for pesticide applications has increased significantly in the last decade due to advances in UAS technology. The UAS systems offer potential for increased precision and reduced time and labor requirements for pesticide application. However, there is very little known of the comparative efficacy between UAS and standard pesticide application systems, especially in aquatic weed management. This research will evaluate UAS application parameters for weed control efficacy and system efficiency.
This is an Extension Implementation Project (EIP). Our Program Priority Areas are IPM Implementation in: Agronomic Crops (28%), Communities (40%), Specialty Crops (24%), and Pollinator Health (8%). The person who will be responsible for grant coordination and budget management, and participation in the SERA3 meetings is Dr. Danesha Seth Carley, Director for the NSF Center for IPM and the Administrative contact is Dr. Rich Bonanno, Director of NC State Extension, and Associate Dean College of Agriculture and Life Sciences. Through NC Cooperative Extension programs and diverse transdisciplinary team collaboration, we work to sustain and enhance environmental stewardship, reduce economic risks for growers and consumers, and protect human health by applying integrated pest management (IPM) in all suitable situations. Our goal is to increase coordination and improve efficiency of translating IPM research to the scientific community and stakeholders; as well as the residents of NC through extension and outreach programs. By working to synergize efforts and leverage resources, we are better able to promote development and adoption of IPM through collaborative programs and broad-based stakeholder participation. With a strong team of experts and close association with our Evaluation Specialist, we are able to document the value of IPM strategies and programs, and provide comprehensive success stories of IPM integration across NC. Through the outputs and outcomes from this program, NC Extension agents and stakeholders will become more knowledgeable about IPM and develop the skills necessary to implement IPM strategies in Agronomic Crops, Specialty Crops, Pollinator Health, and IPM in the Communities.
The goal of the Wilmington District Aquatic Vegetation Management Program is to maintain a healthy and sustainable ecosystem dominated by native aquatic vegetation at the District's dam and lake projects. Long term monitoring of aquatic vegetation will provide information necessary to identify trends and evaluate the effectiveness of management actions in public waters. Failure to identify effective and efficient methods to promote native aquatic vegetation and control invasive aquatic vegetation will result the degradation the environment and public resources. Knowledge gained will benefit public land managers addressing aquatic vegetation challenges in the region.
Flopyrauxifen-benzyl (ProcellacorTM) is the newest chemical control option available to aquatic plant management. It can be used to selectively treat many of the troublesome aquatic weeds that are listed on North CarolinaÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢s Noxious Weed List including Hydrilla verticillata (hydrilla), Ludwigia hexapetala (creeping water primrose), Myriophyllum spicatum (Eurasian watermilfoil), and Alternanthera philoxeroides (alligatorweed). The primary goal of this project is to develop appropriate recommendations for noxious aquatic weed control in North Carolina utilizing new herbicide technology.
The southeastern United States (US) is the richest region of global diversity for freshwater mussel, snail, fish, and crayfish, and is, therefore, a region of high conservation priority. However, this high regional biodiversity intersects with intense pressures of energy mining and development, urbanization and sprawl, increasingly intensive agricultural practices, and growing demands on water and other natural resources for human use. Nestled within this complex landscape, and falling within this rich faunal province, North Carolina contains streams that drain to the Interior Basin (Tennessee ÃƒÂ¢Ã¢â€šÂ¬Ã¢â‚¬Å“ Cumberland) in the west and to the Atlantic Ocean (Atlantic Slope) in the Piedmont and East. The species of freshwater mussels (Unionoida), snails, and fish vary among these regions of the state, face differing landscape and water quality challenges, and, therefore, have differing statues of conservation concern. For example, North Carolina once supported more than 60 species of freshwater mussels, but unfortunately, 50% of these species are now designated as Endangered, Threatened, or of Special Concern and the stateÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢s 161 freshwater fish of conservation concern are also likely integral to the unique unionoid mussel life cycle, serving as obligate hosts during the musselsÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢ parasitic larval stage. Because of these declines and degree of imperilment, protection, restoration, and conservation of these irreplaceable aquatic organisms are paramount. The proposed research will specifically benefit these imperiled mollusks and non-game fishes and contains objectives related to their captive propagation and culture, improvement of their water quality and riparian environment, and better understanding of their ecosystem function and services. The specific tasks include: (1) propagation and culture of the federally endangered Dwarf Wedgemussel, the at-risk Yellow Lance mussel, and the at-risk Magnificent Ramshorn snail; (2) understanding the ecosystem functions and services provided by native freshwater mussels and their associated economic and social benefits to humans and other wildlife; (3) determining the effects of transportation and energy production stressors on the survival, health and well-being of native freshwater mussels; and (4) assessing the integrated risk, ecology, and control of Giant Lyngbya (an invasive Cyanobacteria species) on native mussels. These collective projects will provide natural resource managers and other decision makers with the tools, organisms, and science-based information needed to restore, improve, and conserve these important faunal resources.
This Work Plan reflects a cooperative relationship between North Carolina State University and Animal and Plant Health Inspection Service (APHIS), Plant Protection and Quarantine (PPQ). It outlines the project specific goals, objectives, and anticipated accomplishments as well as the approach for conducting research demonstrations of herbicide treatment applications with an unmanned aerial system platform for discriminant treatment to invasive aquatic plants. This project is a collaboration with the APHIS Methods Development Engineer and Weed scientists at North Carolina State University with expertise in use pattern, spray deposition and efficacy and the related roles and responsibilities of the parties as negotiated.
Through North Carolina (NC) Cooperative Extension programs and diverse cross-disciplinary team collaboration, we work to sustain and enhance environmental stewardship, reduce economic risks for growers and consumers, and protect human health by applying integrated pest management (IPM) in all appropriate settings, and to increase coordination and improve efficiency of translating IPM research through extension programming. By working to synergize efforts and leverage resources, we are better able to promote development and adoption of IPM through collaborative programs and broad-based stakeholder participation. With a strong team of experts and close association with our Evaluation Specialist, we are able to document the value of IPM strategies and programs, and demonstrate to our stakeholders that IPM works. Through the outputs and outcomes from this program, NC Extension agents and stakeholders will become more knowledgeable about IPM and develop the skills necessary to implement IPM strategies and build adoption of IPM in Agronomic Crops, Specialty Crops, Communities, and Pollinator Health. To accomplish our goals and address stakeholder needs for the 2017 CPPM-EIP program, we have 3 main objectives which we will tackle as specific program teams. These include 1) To develop and employ Extension Agent Trainings/In-Services to help agents to be effective communicators of IPM tactics, to build confidence in their knowledge of IPM strategies, and to foster high levels of trust and credibility in their local communities in Agronomic crops, Specialty crops, Communities, and/or Aquatic environments; 2) Deliver IPM Information to stakeholders in a variety of North Carolina settings so that through these activities, NC Extension agents and stakeholders will become more knowledgeable about IPM and develop skill sets to be able to implement sound IPM practices; and 3) Offer tools that will improve Pest Monitoring and Pest Forecasting protocols for pests of importance to NC Agronomic and Specialty Crops and enable enhanced searching and output features on the IPM Portal.
Aquatic invasive species such as Hydrilla verticillata (L.f.) Royle (hydrilla) are a threat to native plant ecology, biodiversity, and economic functions. Without natural predators or pathogens to provide population control, these invasive species readily dominate aquatic ecosystems.Hydrilla is a submersed, rooted macrophyte native to regions of Asia. The species has two triploid biotypes (monoecious and dioecious) that have invaded the continental United States. The overarching goal of this research is to gain insight about the new hydrilla biotypeÃƒÂ¢Ã¢â€šÂ¬Ã¢â€žÂ¢s basic biology and methods of control, using methods currently employed in monoecious and dioecious hydrilla control as a baseline. We also seek to determine vallisneria populations best suited for native planting following management of invasive aquatic species such as hydrilla.
