Characterization of Phomopsis species in the US: Species prevalence, pathogenicity and development of a greenhouse screening technique
Investigator: Sam Markell, NDSU
Description: This research project has one short term (this year) and four additional long term objectives.
Funded Amount: $39,570
- Characterization of the species and their prevalence causing phomopsis on sunflowers in North America, focusing primarily on North Dakota, South Dakota and Northwest Minnesota,
- Develop and test a method for screening sunflower germplasm for phomopsis in the greenhouse,
- Determine the aggressiveness of these species on phomopsis in greenhouse,
- Compare the U.S. Phomopsis specie(s) in the United States to those in other important sunflower growing areas in the world (winter nursery and production areas), and (E) educate a Ph.D. level sunflower pathologist.
