Kansas State University earns 2016 Tree Campus USA Recognition

Who are the future leaders in the Kansas green industries? Our K-State grads! Why are they so amazing? These students have excellent opportunities to engage in hands-on, practical learning.

As one piece of that, K-State was recently named a Tree Campus USA for the third year in a row. Congratulations to Dr. Cathie Lavis for leading the efforts, and kudos to the whole team.

More details are available in this article from K-State Communications:


As another benefit, ALL K-State students, faculty, staff, and visitors get to enjoy our beautiful campus.


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

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).


Iris leaf spot – spring cleaning to disrupt fungal life cycle

(Megan Kennelly, KSU Plant Pathology)

Irises are a popular plant, often grown in large groups. Iris leaf spot is a fungus that can cause mild spotting to severe dieback.The fungus spreads by spores that are dispersed in wet weather.

Red-brown spots with yellow halo:

A closer view – the black bumps are spore-producing structures:


Another close-up view of one spot:

Spots can coalesce to cover a large area

More significant dieback:

Where does that fungus spend the winter? In old infected leaves. Get those outta there to reduce your risk of infection in the new year. Clearing out old infected plant tissue breaks the life cycle.

More information about managing iris leaf spot is available in a recent article by Ward Upham in the KSU Horticulture News

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.

Why YOU should come to the Kansas Turfgrass Conference!

Are you still deciding whether to attend the Kansas Turf Conference next week?

Here are just a few of the many reasons why that answer should be YES!

* Looking for some networking opportunities? Over 400 of your peers in the turf, landscape, and ornamentals industry have already signed up. The trade show floor will be a great place to exchange ideas, see old friends, and meet some new ones. In last year’s conference evaluation, 96% of survey respondents said, “The conference gave me opportunities to network with others in the industry.”

* In last year’s evaluation, 96% of survey respondents said, “The conference was worth my time and effort.” We think this year’s conference will be too!

* In last year’s evaluation, 92% of survey respondents said,”The conference increased my understanding of integrated pest management.” This year includes  many different sessions about insects, diseases, and weeds, with lots of opportunities to earn pesticide credit including a hands-on disease id booth in the trade show.

* In last year’s evaluation, 91% of survey respondents said, “The conference increased my understanding of people-related skills.”  The 2016 conference will feature hot new topics about how to be a better competitor, cultivating professionalism, and more business topics.
