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.

“We have hit the mother load!” Behind Throckmorton Hall I ran into the largest patch of Wild Violet I have ever seen so we decided that would be a good Turfgrass Selfie Series Video. Enjoy!
Also, we tried to work out some of the kinks from the first episode but still have a ways to go to get all the kinks out. The goal of this video series is to use our phones and to make short videos without too much editing and taking too much time but to deliver insightful information. With that being said we can’t cover everything in the short video but at least it gets the basic information out there.
So for the second Turfgrass Selfie Series we bring you wild violet control… “We have hit the mother load!”

Last night while cruising through Facebook I can across a blog that Dr. Nick Christians from Iowa State wrote about orchardgrass. Take a good look at the pictures because you might have some in your lawn too.
Now controlling orchardgrass is a different story. Just because we can identify it doesn’t always mean it is easy to control. Unfortunately, there no selective control options that we can use in cool-season turfgrass systems. Many different chemistries (mesotrione, chlorosulfuron, metsulfuron, and more) have been tested at Purdue but didn’t even provide satisfactory control.
So with that being said the options out there right now are physical removal, blah… Or non-selective herbicides like glyphosate.
Always remember to READ THE LABEL for the correct rate, turfgrass tolerance, and specific instructions before application!!!

What a beautiful day we had this year for the 2014 KSU Turfgrass Field Day. Thank you to all the attendees, vendors, sponsors, faculty, staff, students and anyone else that was out at the field day!
If you weren’t able to make it, I decided to post some pictures and links to research reports so you can get more information about each stop that we had this year.

Also, I will include the QR codes. These codes can be scanned by your phone and will take you directly to the information! Check it out!
This year my stop at field day was “Kansas Turfgrass Weed Control Update”. Here is discussed one of the most problematic weeds in cool-season turfgrass, bermudagrass. I talked about both selective and non-selective methods. For more information about bermudagrass removal check it out here. https://blogs.k-state.edu/turf/non-selective-bermudagrass-removal/

KSU Turfgrass Research Technician and Graduate Student, Jake Reeves, presented information on the best management practices for buffalograss establishment. Jake has been conducting some great research that will really help us out when we want to convert cool-season turfgrass to buffalograss. For more information check out his latest blog post. https://blogs.k-state.edu/turf/establishing-buffalograss-in-golf-course-roughs/

Zane Raudenbush, KSU Turfgrass Graduate Student, and Dr. Keeley has been conducting research on the cultural management of moss infestations on bentgrass putting greens. Zane got to display some great looking research on one of the putting greens out at the Rocky Ford Turfgrass Research center looking at cultural practices in conjunction with chemical applications of carfentrazone. For more information check out his latest research report. http://www.ksre.ksu.edu/bookstore/pubs/SRP1107D-MOSS-FERTILITY.pdf

Ever wondered what was the best preforming kentucky bluegrass cultivar? Well, Evan Alderman, KSU Turfgrass Graduate Student, discussed the best preforming Kentucky bluegrass cultivars in Manhattan, KS. This study is part of the Nation Turfgrass Evaluation Program (NTEP). Check out the NTEP website for the most current bluegrass cultivar information. http://www.ntep.org/data/kb11/kb11_14-2/kb11_14-2.pdf And some more information on prolonged drought and recovery characteristics of Kentucky bluegrass cultivars http://www.ksre.ksu.edu/bookstore/Item.aspx?catId=545&pubId=17861

Although this summer has seen to be pretty mild when it comes to diseases in turfgrass, Dr. Kennelly discussed both turf and landscape disease updates. Don’t forget to periodically check the blog as Dr. Kennelly updates the blog with what is going on with diseases in Kansas. Here is some more information on all sorts of turf disease publications. http://www.plantpath.ksu.edu/p.aspx?tabid=551

Is the grass really greener on the other side? Ross Braun, KSU Turfgrass Graduate Student, presented on using paints and pigments for coloring turfgrass. Ross has conducted many trials looking at painting zoysiagrass and buffalograss. He has evaluated different paints and pigments as well as rates and spray volumes. Check out his latest research update on paints and pigments. http://www.ksre.ksu.edu/bookstore/Item.aspx?catId=545&pubId=17867

As it is hard to grow cool-season turf in Kansas it is also tough to grow warm-season turf. Dr. Fry presented about the best zoysiagrass and bermudagrass cultivars for Kansas. He discussed everything from color to pest tolerance. This included information about how the cultivars held up to last winter. For more information about the zoysiagrass and bermudagrass cultivars here is a great research report about winter survival on the 2013 NTEP zoysiagrass and bermudagrass in Kansas. http://www.ksre.ksu.edu/bookstore/pubs/SRP1107G-NTEP-ZOYSIA-AND-BERMUDA.pdf
Thanks again to everyone that came out to this years KSU Turfgrass Field Day. It was a great success and hope to see you next year in Olathe. Also, don’t forget this December is the Kansas Turfgrass Conference in Topeka. It’s going to be great as well. Keep and eye out for more information on registration.
