South central and southeast Idaho cereals program

A group learning about wheat and barley field trials.

South central and southeast Idaho cereals program

The University of Idaho Extension cereals program for south central and southeast Idaho is based at the University of Idaho Aberdeen Research and Extension Center.

The purposes of the program are to:

  • Evaluate and report cereal cultivar performance at various locations in south central and southeastern Idaho
  • Evaluate and report management trials involving production and marketing
  • Train and support cereal producers, agribusiness personnel and UI Extension educators
  • Support state and private breeding programs
  • Evaluate usefulness of new products and cereals management techniques
  • Study cereal disease problems and find ways to manage new diseases

Cereal disease

The UI Extension cereals program is responsible for researching local cereal disease concerns and distributing the information to producers and agribusinesses.

USDA-ARS cereal root disease project

The UI Extension Cereals program conducts research on cereal root diseases in Idaho under the USDA-Agricultural Research Service. This project is part of the USDA Root Disease and Biological Control Research Program based out of Pullman, Washington.

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
  • Identify the effects of cropping systems on root pathogen population size and diversity, and on disease epidemiology
  • Identify useful wheat and/or barley germplasm with performance against root pathogens

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, as well as 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. A combination of agronomic practices and biological and chemical treatments will control root disease.

Explore other projects under the USDA Root Disease and Biological Control Research Program through the USDA-ARS website.

Growth stages

Learn how barley and wheat develop, critical growth stages and how management inputs affect yield and grain quality. Wheat and barley are both cool season crops that have many similarities in growth stage development and management needs.

Small grains reports

Small grain varieties differ from year to year and are grown in multiple locations around the region. Please view variety trial locations or small grain reports for more information.
