TURFGRASS RESEARCH

Mattox's Microdochium Patch Research Available

Clint Mattox has completed his masters’ dissertation at Oregon State University and his research is available to you, thanks to the donations the Northwest Turfgrass Association has made to the turfgrass management program at Oregon State.

“Managing Microdochium Patch Using Non-Traditional Fungicides on Annual Bluegrass Putting Greens” is available by following this link: hdl.handle.net/1957/57194

Here is a brief description of the research:

Currently, fungicide applications are the predominant method of control for the cool-weather pathogen Microdochium patch. Increasing pesticide restrictions have generated concern regarding management of Microdochium patch. Three separate field trials exploring non-traditional fungicides were conducted between 2013 and 2015 on an annual bluegrass sand-based putting green at the Lewis Brown Horticulture Farm in Corvallis, Ore. The objective of the first project was to evaluate the effects of the cultural practice of rolling in combination with mineral oil and fertility on Microdochium patch incidence. The objective of the second trial was to quantify the effects on Microdochium patch incidence using biological control products in combination with rolling. Finally, the objective of the third experiment was to quantify the effects of different nitrogen and iron sulfate rates in combination with simulated golfer traffic on the effects of Microdochium patch incidence as well as turfgrass recuperation.

Mattox currently is working on his PhD at Oregon State and is continuing his exploration of “Alternatives to Non-Traditional Fungicides.”
