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.

Cut-and-burn those pine wilt infected trees

(Megan Kennelly)

Got pine wilt?


Get that tree outta there! Chop and burn or chip, making sure not to leave stumps. Get this done by April 1!

You know the drill. This disease has been killing our pines for decades. It is caused by a nematode that is spread by a beetle. The nematodes and beetles spend the winter in dead and dying trees. The beetles, loaded up with nematodes, start emerging in late April or early May and spread to new trees.

In the eastern 2/3 of the state, if you have a dead pine, there is a decent chance it has pine wilt. We have detected pine wilt a handful of times in western Kansas too.

Get those pine-wilt infected dead trees out of the landscape to help prevent spread to surrounding trees.

Pines have multiple problems though, and if you have any doubt you can work with your KSRE Extension agent to ship a sample up to KSU. For more information on pine diseases, check out our publication about Pine Diseases in Kansas

KSU Tree Reference

(Megan Kennelly, KSU Plant Pathology)

If you attended one of our K-State educational events this winter you might have had the chance to do some hands-on work with our Tree and Shrub Problems in Kansas book.

Did you mean to get a copy, but didn’t get around to it yet? If so you can download the pdf for free or order a print copy on our KSU Extension Bookstore.


Or, call the Extension Distribution Bookstore at 785-532-5830 to order a copy. Ask for the book by name, or by its publication number (MF3132).


Changes to Worker Protection Standard

(Megan Kennelly)

There are some new changes to the Worker Protection Standard (WPS). If you attended the Core Hour or other pesticide license trainings in the last year or so you should have learned about some of these changes already.

If you did not receive the information yet, here are some resources you can check out.

Quick summary from University of Kentucky:

Revisions to Worker Protection Standards (WPS) Become Effective in 2017

Goldilocks and the three trees. (Site conditions that are “just right.”)

When it comes to trees:

Trees need water. Not too much, not too little, but just right.

Trees need appropriate temperature. Not too hot, not too cold, but just right.

Trees need to prune. Not too much, not too little, but just right.

If you are looking for some cozy winter reading, you can check out our publication about Tree and Shrub Problems in Kansas.

In addition, I just came across a great publication from University of Kentucky that discusses tree and shrub decline. The information is similar to parts of the Tree and Shrub Problems in Kansas book, but sometimes it is helpful to read information from a new source since everyone presents information in a slightly different way. The reference is Stress and Decline in Woody Plants.

Happy reading!
