2009-2010 Evaluation of Preventative Fungicide Applications For the Control of Gray Snow Mold on An Annual Bluegrass/Kentucky Bluegrass Fairway

Objective

The purpose of this trial was to evaluate a single preventative application of various fungicides for the control of gray snow mold on a golf course fairway.

Materials and Methods

The trial was initiated on October 23rd (after the last mowing) on the 11th fairway of the Meadows Golf Course (4,160 feet elevation) located in the Sun River Resort in Sun River, Oregon, 15 miles south of Bend.

Microdochium Patch Fungicide Control Strategies

Avoiding Buildup of Resistant Fungi

  • Most failures are probably not due to fungal resistance to fungicides.
     
  • Fungal resistance is most likely to develop where you over use systemic fungicides and don’t alternate modes of action.

    Examples in the PNW on Microdochium Patch: Clearys 3336, Chipco 26GT, and Heritage.
     
  • Pathologists have numerous theories on the best strategies for managing fungicides to avoid resistance.

Turf Adaptation & Ecology Part 2: Turf communities in Western Oregon

Turf adaptation implies that commonly planted grasses have specific climatic conditions in which they thrive. Therefore, if we know the climate we should be able to predict what grasses will have a reasonable chance to prosper. The converse is also true. If we plant grasses in climates where they are not adapted, we can expect to have problems growing a healthy lawn. One way to depict turf adaptation is through maps.
