What have you been up to? – Undergraduate Research Projects

(By Jared Hoyle, KSU Turfgrass Research and Extension)

As the temperatures start getting warmer, friends and neighbors start getting out more.  So when I run into them, the first question I get is “What have you been up to?”.  Many times people think winter is slow because the grass is not growing but actually during the winter is when we try and get a lot of things done that we don’t have time to get to in the warmer parts of the year.  But one thing that we have been up to is undergraduate research projects.

In the fall of 2016 I had three students come to my office interested in conducting an undergraduate research project.  I told them that the purposes of an undergraduate research projects are; 1. Answer a question for an issue that turfgrass managers face, 2. Learn the process to conduct research and, 3. Relate your research to more than just the turfgrass manager but have a social impact.  All three of them agreed then we started brainstorming and came up with three projects.

Undergraduate Research Project #1 – Student – Peyton South

The Effect of Human Insect Repellents on Turfgrass Growth and Recovery

Ever seen this before? https://www.extension.iastate.edu/turfgrass/blog/dr-nick-christians/mosquito-spray-can-kill-grass

That is what bug spray can do to your turf.  Peyton wanted to look into it more and see if there are differences in not only the bug sprays but if there is recovery. He is currently taking data and we will get that information out there once the project is complete.  Here are some pictures of the project.


Undergraduate Research Project #2 – Student – Dani McFadden

Will Turfgrass Colorants Blemish Clothing?

Dani’s research project was inspired by a question I got from in education event this past year. There has been lots of research on turfgrass colorants and how long they last but what will it do to the clothing of the athletes if they fall.  So Dani went out and applied a variety of different turfgrass colorants, pulled clothing across the colorants (after the recommended drying time) and then analyzed how much colorant blemish the clothing. Once her project is complete then we will be able to determine which products to recommend to athletic field managers so they can rest assure they won’t have any phone calls about stained clothing.


Undergraduate Research Project #3 – Student – Gage Knudson

Prediction of baseball on-base percentage due to infield mowing height

Sometimes there is only a spit second at first base between a baseball batter and the throw at shortstop to determine if the runner is out or safe.  One component of that split second is how fast the baseball moves through the infield.  Holding all other factors constant, Gage manipulated mowing height of a simulated baseball infield to determine the speed of a ground ball hit to the shortstop.  Then he can predict the out percentage at first base.  Gage’s interest in this project not only helps field managers with maintenance of the field but shows how important it is for the coach of baseball team to communicate with the grounds manager.  To simulate a constant speed he used a pitching machine that was aimed at the infield.  Believe it or not that one slit second can be influenced just by the mowing height of the infield.

New Weed Control Publication For Turfgrass Professionals

(By Jared Hoyle, KSU Turfgrass Research and Extension)

In 2016 Dr. Aaron Patton and Daniel Weisenberger reached out to surrounding universities to collaborate on producing a multi-state Turfgrass Weed Control for Professionals Publication.  There are 11 states, including Kansas, that worked together to help produce the 2017 edition.


Guide provides weed identification and control information that turfgrass professionals can use to develop effective weed control programs for golf courses, athletic fields, sod farms, lawns, and other turfgrass systems. Recommendations apply to most states, with input from experts in IL, IN, IA, Kansas, KY, MI, MN, MO, NE, NY, OH, and WI.

It contains images and information for identifying 105 different weed species.



Covers herbicide selection in:

  • Nonselective herbicide/fumigants for renovation
  • Nonselective herbicides for border maintenance
  • Preemergence herbicides
  • Postemergence broadleaf herbicides
  • Postemergence grass herbicides
  • Postemergence sedge herbicides
  • PGRs for general turf
  • PGRs for putting greens
  • Herbicides labeled for putting greens (PRE and POST)

The publicationl also covers many other weed control aspects like;

  • Which herbicide works best for each weed.
  • Includes notes and comments on each herbicide.
  • Control of tough weeds.
  • Provides handy comparisons of broadleaf herbicide ingredients.
  • Covers fundamentals of how herbicides work
  • frequently asked questions.

Low Water Use Turfgrass Event – Hays, KS

Tuesday evening, Sept. 20 is set for the annual Horticulture Night at the Kansas State University Agricultural Research Center in Hays. This year the emphasis is on low water use turfgrass demonstration plots, tomato and pepper varietal trials, and the Prairie Star flower performance trials.  The event is scheduled later in the summer this year than usual so attendees can better view the results of the complete season.

Dr. Jared Hoyle will be there to answer any turfgrass questions you might have!

Update on KSU Turfgrass Program and Facilities in Manhattan and Olathe

(by Jared Hoyle; KSU Turfgrass Research and Extension)

As you turfgrass managers know it has not been a slow winter.  It was hot, it was cold, it snowed, it was warm again, winter was late and it looks like spring has come a little early.  With winters like that it keeps turfgrass managers busy.

This winter the KSU Turfgrass Team has also been busy.  New river pumps were installed at Rocky Ford Turfgrass Research Facility, new research plots are being installed, plans for new irrigation are in the works in Manhattan and Olathe, and believe it or not we finally have concrete in the turfgrass shop floor in Olathe.  Moving’ on up!

On behalf of the turfgrass team, we would like to thank the Heart of America and Kansas Golf Course Superintendents Associations for the donation of the concrete floor in Olathe, Martin Lane from Midwest Laser Leveling for donating time and equipment to prepare new research plots at Rocky Ford, Kevin Marks from SiteOne Landscape Supply for the new research plot irrigation design, and everyone involved in the new river pump installation at Rocky Ford.  Below are a list of pictures from all these events.
