Accomplishments
Project Objectives:
- Assess the current status of curly top and set priorities for integrated research on curly top disease.
- Characterization of curtovirus strains including virus genetic diversity, new virus strains and virus in new hosts.
- Organize research on the biology and ecology of the leafhopper, virus transmission, and the role of weed hosts in curly top in the western US.
- Organize research to improve virus and vector management.
- Provide a national platform for education on curly top disease, virus/insect/plant ecology and management, collaboration among scientists involved in these activities, and extension of research-based information for producers.
Objective 1: Accomplished through annual meeting presentations and goal setting. See above minutes.
Objective 2: Worked toward this goal in individual research programs. See above minutes.
Objective 3: Made progress toward the goal. See above minutes.
Objective 4: Made progress toward goal. See above minutes.
Objective 5: Collaborative curly top projects were carried out between Carl Strausbaugh and Kylie Swisher Grimm and between Punya Nachappa, Oliver Neher, Carl Strausbaugh, and Raj Majumdar
Impacts
- Curly top is an economically important disease in many states in the western U.S. Members of the WERA1007 group increased the knowledge of the virus biology, its transmission, and the management of the disease. The range of virus strains was expanded in California, Colorado, Washington, and New Mexico. The resistance to curly top in sugarbeets was assessed, aspects of the curly top virus transmission were characterized, and the use of foliar insecticides for vector control was tested. These findings should help improve the management of curly top in sugar beet and other affected crops in the western U.S.
