Gary Deters takes on a New Role

By Eric Watkins

We are excited to announce that Gary Deters will be our new lawn water conservation educator!  Gary, who spent 23 years in golf course turf management, six of those years as a superintendent at St. Cloud Country Club, has been our field facility manager since March 2020. Gary has been an excellent addition to our team, ensuring that our research plots are maintained well, and experimental treatments are applied carefully and consistently.


Does rolling greens following a contact fungicide application affect results?

By Gary Deters

Over the last two seasons we have been researching if rolling greens post contact fungicide application affects the efficacy and effectiveness of the fungicide. The results of the trial could possibly take out the guesswork and allow golf course superintendents to make confident decisions. Rolling greens (Figure 1) is a cultural practice golf course superintendents use to help increase green speeds, remove dew, and promote smoothness of the putting surface.

An old mower to the rescue

By Gary Deters

Like most turfgrass areas, a high percentage of our research plots need to be mowed consistently. Our creeping bentgrass research golf greens are cut at 0.125” and the task requires a special mower and reel setup. Many plots are cut at 2.5” to 3.5” with a push or riding mower, similar to what is used by a typical homeowner. So, with all the research plots and mowers we have, you might think we have everything we need to get the job done. In most cases that is true, but for a new trial conducted by members of the turf group, we had a bit of a problem.


Observing growth

By Gary Deters

As turfgrass managers we have a responsibility to observe the growth of the many varieties, cultivars, and species of turfgrass from seed to maturity. Pretty obvious, right? Observing growth is more than just looking at the turf with our own eyes from day to day. I have mentioned in a previous blog post about the importance of before and after photos and while they can be a great resource (Figure 1), there are more ways to see the progress of growth.
