Research Project: Identification and Management of Soilborne Pathogens of Wheat and Barley in Idaho

Location: Wheat Health, Genetics, and Quality Research

Project Number: 2090-22000-019-002-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Sep 1, 2019
End Date: Aug 31, 2024

Objective:
The objectives of this cooperative research are to identify, characterize and control soilborne pathogens of wheat and barley, such as Rhizoctonia, Pythium, Gaeumannomyces, Bipolaris and/or Fusarium, which cause root and crown rot diseases; to identify the effects of cropping systems on root pathogen population size and diversity, and on disease epidemiology; and to identify wheat and/or barley germplasm with resistance/tolerance against root diseases.

Approach:
Root and crown rot diseases will be identified and characterized through a combination of laboratory, greenhouse and field studies. The ecology of soilborne pathogens and effects of cropping systems on pathogen population size and diversity and disease epidemiology will be determined using plant pathology, microbiology and molecular biology methods. Wheat and barley germplasm will be screened for resistance or tolerance to soilborne pathogens in the field and greenhouse. Practical root disease control will be accomplished through a combination of agronomic practices and biological and chemical treatments.
