Grey Leaf Spot – All the way from 2015.

(By Jared Hoyle, KSU Turfgrass Research and Extension)

Someone told me and I am not sure if it is correct or not, “that grey leaf spot will infect crabgrass before it hits our desirable turfgrass species”.  The other day I saw some grey leaf spot crabgrass in a ryegrass lawn and got me thinking that this is about the time grey leaf spot starts to kick in around here.  I went back through the blogs and back in 2015 (Actually August 25, 2015) I posted about grey leaf spot.

I wanted to pass along the blog again for everyone that may have had grey leaf spot in the past.

Effect of Dormant ‘MidIron’ Bermudagrass Colorant Applications on Clothing Blemishing

Effect of Dormant ‘MidIron’ Bermudagrass Colorant Applications on Clothing Blemishing

(By Jared Hoyle, KSU Turfgrass Research and Extension and Daniele McFadden, KSU Turfgrass Undergraduate Research Assistant)

Summary. Minimal research exists on potential clothing blemishing when athletes contact turfgrass applied with colorants. Field trials were conducted to test the effect of turfgrass colorant applications on clothing blemishing if a athlete is to come in contact with the playing surface. Turfgrass colorants will adhere to turfgrass leaf blades and do not blemish clothing. Although, tested turfgrass pigments did result in significant blemishing of clothing.

Rationale. Bermudagrass (Cynodon dactylon) is a warm-season turfgrass used on athletic fields in the Midwest. Although a desirable turfgrass species for athletic fields it fails to maintain acceptable green color during winter. Turfgrass colorants have been utilized to maintain acceptable green turf color through dormancy periods. Athletes of all ages play on sports fields where colorants have been applied. Extensive research has explored turfgrass colorants on turfgrass quality but minimal research exists on potential clothing blemishing when athletes contact turfgrass applied with colorants.

Objectives. The objective of this research was to determine if turfgrass pigments and paints blemish athletic clothing after the recommended dry time.

Study Description. Field research trials were initiated Feb. 16, 2017 at Rocky Ford Turfgrass Research Center in Manhattan, KS on dormant ‘MidIron’ bermudagrass maintained at 3.8 cm. Treatments were applied to 1.5 by 1.5 m plots arranged in a randomized complete block design with four replications. Treatments consisted of three paints (Wintergreen Plus, Green Lawnger, Endurant Premium), one pigment (Envy) and a non-treated control for comparison. All colorant treatments were applied at 1:6 (v:v) dilution in 1,234 L ha-1 spray volume. After recommended drying time (4 hrs), a white cotton t-shirt was pulled 1.5 m across the plot weighted down with 11.4 kg. Digital image analysis was used to determine percent blemishing of t-shirt area. Data was subjected to ANOVA in SAS and means were separated according to Fisher’s Protected LSD at 0.05 significance level.

Results. Envy (turfgrass pigment) resulted in the highest blemished clothing percentage (60%). All other treatments were no different than the non-treated (Figure 2). Results demonstrate that the tested turfgrass paints safely adhere to the turfgrass canopy and do not blemish athletic clothing.

How to plant trees the right way!

Here in the K-State Diagnostic lab we deal with trees that are planted WRONG all the time! When trees are planted wrong, they start out extra stressed from day one. Trees are stressed enough just trying to live in our crazy Kansas weather, so, how do you plant them RIGHT?

Check out this easy-to-use guide from Dr. Cathie Lavis:

https://www.bookstore.ksre.k-state.edu/pubs/MF3313.pdf

There is a one-page guide to ball-in-burlap and a one page guide to container-grown trees.

Here’s one thing we don’t want, a big ol’ girdling root! And below that I put some photos I took of a display about planting trees wrong – you can click to zoom in a bit and check it out.

Gloves – an important piece of PPE

I came across a nicely-written article from U of Kentucky about gloves and pesticide safety. It’s pretty short, and worth 2 minutes of your time as a quick review.

For example, did you know this? “Research has shown that workers mixing pesticides received 85% of the total exposure on their hands and 13% on their forearms. The same study showed that wearing protective gloves reduced exposure by 99%.”
