Definitions and Descriptions of Services

Routine Diagnosis includes a visual inspection of a sample and may include examination with a dissecting microscope and/or a compound microscope.

An ELISA test is an enzyme-linked immunosorbent assay that uses antibodies and color change to detect specific organisms. In the Schutter Diagnostic Laboratory, we use ELISA mainly for the detection of wheat streak mosaic virus. While the test is very sensitive, it is time-consuming and will take days until results are available.

Culturing includes the isolation of a pathogens by transferring the affected plant tissue onto selective agar plates, followed by incubation.

Immunostrips are lateral flow devices for the rapid detection of pathogens. Test kits that the Schutter Diagnostic Laboratory has routinely available are:

  • Fungi:  Phytophthora sp.

  • Viruses:  Tobacco Mosaic Virus (TMV), Cucumber Mosaic Virus (CMV), Impatiens Necrotic Spot Virus (INSV), and Tomato Spotted Wilt Virus (TSWV).

  • Bacteria:  Clavibacter michiganensis subsp. michiganensis (CMM) and Erwinia amylovora (Ea).

PCR, polymerase chain reaction, is used to detect pathogens by amplifying the specific DNA of organisms. The Schutter Diagnostic Laboratory uses PCR mainly for the detection of wheat streak mosaic virus.

If you are uncertain which testing is needed, please contact us for more information (diagnostics@montana.edu or 406-994-5150).
