UNL Turfgrass Sciences Team provides industry-leading expertise

09/01/2022

Labor challenges are nothing new to the turfgrass industry and labor shortages have been especially hard felt over the past two years of the COVID-19 pandemic. The University of Nebraska-Lincoln Turfgrass Sciences program is not immune, and we are also facing a temporary personnel shortage. We are currently working to get back to a full roster and in the absence of a full team it has been challenging to communicate all the great things being done at the University.

Working in the heat is needed on turfgrass facilities

07/27/2022

Working in the heat is needed on turfgrass facilities but letting the weather cause serious harm to you and your workers is not. The following is from Centers for Disease Control and Prevention Heat-Related Illness page.

Turf weeds in the heat

Be cautious with herbicide applications and high temperatures

07/27/2022

The projected weather outlook is predicting temperatures exceeding 90 F throughout Nebraska. Elevated temperatures slow cool season turf (Kentucky bluegrass and tall fescue) growth, especially when combined with low precipitation. Warm season grasses like zoysia and buffalograss increase growth potential during high temperatures. Summer annual grassy weeds like crabgrass, goosegrass and foxtail and the obstinate perennial weed, yellow nutsedge outgrow, and may sometimes dominate, cool season turfs during the summer months.

Ascochyta leaf blight

Ascochyta leaf blight

06/29/2022

Most resources indicate that Ascochyta leaf blight is a minor disease because injury is usually temporary, and does not result in turf loss. Kentucky bluegrass is most commonly affected, but infection of other cool-season grasses is also possible. Outbreaks of this disease have been common as far west as central Nebraska this year.

Mid-season crabgrass management and control

07/27/2022

This time of year, especially in turf thinned by drought, disease, traffic or other afflictions, crabgrass and other summer annuals may pop up, even if the turf was treated with an effective preemergence product. No product is 100% effective even when applied correctly “Escapes” may occur for a number of reasons including misapplication. Regardless of the reason or type of turf area, older and larger crabgrass is much more difficult to control than younger plants, making mid-season the optimal time to control crabgrass post emergence.

High temps are hard on cool-season grasses

07/06/2022

I just returned from a trip to the Pacific Northwest where it was a cool 70F. To get caught up on field research, I headed straight to the field where the heat index was 104F. I’ll share the mysteries and importance of temperature acclimation in a future article, but I was not adjusted to those temperatures. The heat and humidity are just as stressful to the turf we manage. The following was adapted from a Turf iNfo prepared by former UNL professor Zac Reicher.

Amundsen promoted to full professor

06/29/2022

Dr. Keenan Loder Amundsen is an important member of our turfgrass sciences team and is being promoted to full professor in August 2022. Keenan joined the University of Nebraska-Lincoln Turfgrass Sciences team as a Turfgrass Geneticist in 2011. Interviewing in January of that same year, the John Seaton Anderson Turfgrass Research Facility near Mead was under several inches of snow, and he couldn’t see the turfgrass germplasm that he’d soon be studying. Keenan and his family moved to Lincoln in May to start his career as an Assistant Professor of Turfgrass Genetics.
