Project Number: 5348-22000-013-03
Project Type: Specific Cooperative Agreement

Start Date: Sep 13, 2004
End Date: Sep 06, 2009

Objective:
The objective of this cooperative research is 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 useful wheat and/or barley germplasm with performance against root pathogens.

Approach:
Root and crown rot diseases will be identified and characterized through a combination of laboratory, greenhouse and field studies. The ecology of root pathogens and effects of cropping system on pathogen population size and diversity and disease epidemiology will be determined using plant pathology, microbiology and molecular biology methods and approaches. Wheat and barley germplasm will be screened for resistance or tolerance to root pathogens in the field and greenhouse. Practical root disease control will be accomplished through a combination of agronomic practices and biological and chemical treatments. Formerly 5348-22000-012-02S (3/2004).
