The Extension Plant Pathology program at Montana State University focuses on diseases of economic importance in Montana as well as issues faced in the home landscape. We provide plant pest identification through the Schutter Diagnostic Lab and seed testing services for pulse crops through the Regional Pulse Crop Diagnostic Laboratory.

  1. Diagnose and properly treat plant diseases
  2. Provide educational opportunities and diagnostic resources for our clientele
  3. Train first detectors to identify, monitor, and respond to invasive pests
  4. Rapid detection, diagnosis, and communication about pest outbreaks to protect our agricultural biosecurity

To achieve these goals we are involved in national and regional collaborative efforts including the National Plant Diagnostic Network and Great Plains Diagnostic Network. These federally funded programs assist us by providing funding for critical equipment and supplies for diagnostics, educational training opportunities, IT resources, and opportunities to communicate with diagnosticians and researchers in other states.

We also obtain external funding to do research and outreach on important plant diseases and have established an Urban IPM Program to train county agents and landscape professionals about diagnosis and management of plant diseases, insects, and weeds in the home landscape.
