Identification and Control of Root Diseases of Wheat and Barley
Root Disease and Biological Control Research
2009 Annual Report
1a.Objectives (from AD-416)
The objective of this cooperative research is to identify, characterize and control soilborne pathogens of wheat and barley, such as Fusarium, Pratylenchus and/or Heterodera, which cause root and crown rot diseases; to identify the effects of cropping system on root pathogen populations and diversity, and on disease epidemiology; and to identify wheat germplasm with performance against root pathogens.
1b.Approach (from AD-416)
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 populations and diversity, and disease epidemiology will be determined using classical plant pathology and microbiology methods and molecular techniques. Wheat germplasm will be screened for resistance or tolerance to root and crown pathogens in the field and greenhouse. Practical root disease control will be accomplished through a combination of agronomic practices, and biological and chemical treatments. Documents SCA with OSU.

This SCA was recently initiated thus there is no progress to report. Accomplishments from this project will align with Components 2, Problem Statement 2C, Component 3 Problem Statement 3B and Component 4, Problem Statement 4a of NP 303. Progress on this project will be monitored by conversations with the collaborator at professional meetings, through conference calls and by visits to Pullman or Pendelton.
