Field Notes from Valerie Tate

The Noble Foundation is a private agricultural research organization located in Oklahoma. They recently contacted Dr. Robert Kallenbach in search of tall fescue plants that were infected with "wild" endophyte. They are planning to investigate the endophyte fungus which infects tall fescue plants to determine if there are different strains of the fungus, or if all of the naturally occurring endophytes are the same.

When cattle consume tall fescue infected with high levels of the endophyte fungus, the effects can be quite detrimental. The fungus causes blood vessels to constrict, resulting in poor circulation, and this can lead to rough hair coats, lost tail switches and even lost hooves.

Plants were sent from pastures at FSRC and the Southwest Center in Mount Vernon, Missouri, to the Noble Foundation in Ardmore, Oklahoma. Both University of Missouri locations have observed the negative effects of the endophyte fungus. There the plants will be potted and maintained in a green house and tests will be conducted. We look forward to learning more about the endophyte in these plants.
