Research Project: SCLEROTINIA DISEASES

Location: Sunflower Research

2007 Annual Report


1a.Objectives (from AD-416)
Coordinate the development of a Sclerotinia initiative for expanded research to control this devastating disease which affects canola, sunflowers, soybeans, edible dry beans, lentils, peas and other crops. Research should be coordinated with interested ARS, state, and industry cooperators and administered through specific cooperative agreements. Planning workshops and annual meetings involving interested parties will be organized throughout the funding period.


1b.Approach (from AD-416)
Exotic and emerging plant diseases pose severe problems throughout the United States. Their increasing importance may be attributed to the introduction of pathogens into new geographic regions; modification of the environment that favor diseases; change in crop management practices; genetic shits in the pathogen population; and other processes that may give them a competitive advantage.


3.Progress Report
All milestones listed in question 2 comprise the Sclerotinia Initiative Strategic Plan. Each milestone was addressed in FY2007 by components of the 29 specific cooperative agreements and the numerous additional ARS projects funded from the Initiative. Research is ongoing in all areas and substantial progress has been made in Epidemiology and Disease Management and Variety Development/Germplasm Enhancement. Pathogen and Host Genomics research resulted in significant progress, but substantial efforts are still needed in genome sequencing of the pathogen and gene profiling of susceptible and resistant crops. Pathogen Biology and Development research is ongoing, but additional efforts are needed to identify disease infection processes and to characterize virulence among disease genotypes.


4.Accomplishments
The National Sclerotinia Initiative (NSI) contributes to the goals of ARS National Program 303 – Plant Diseases, which is comprised of four components a) Disease Diagnosis: Detection, Identification and Characterization of Plant Pathogens, b) Biology, Ecology, Epidemiology, and Spread of Plant Pathogens and their Relationships with Hosts and Vectors; c) Plant Disease Resistance; and d) Biological and Cultural Strategies for Sustainable Disease Management. NSI progress to date is reported under project number 5442-21220-010-00D. In this continuing project, 5442-21220-023-00D, each of the milestones listed will be addressed during the next 5 years and anticipated progress is currently outlined in the Sclerotinia Initiative Strategic Plan. Definitive plans will evolve depending on cooperators involved in the research projects, subject to the availability of research funds each year.
