Spots, spots, and more spots!

KSU horticulture

Spots, spots, and more spots! Do you have spots in your lawn? Hopefully not, but if you do there is an answer to at least one of the causes of lawn spots. Dollar spot is a common problem on all turfgrasses grown in Kansas, including Kentucky bluegrass, tall fescue, perennial ryegrass, bent grass, buffalo grass, bermudagrass, and zoysia grass. The disease may occur regardless of management or soil fertility, although damage usually is most severe if there is a deficiency of nitrogen. Dollar spot results in the formation of small, roughly circular, bleached patches in the lawn. The patches are more numerous in areas where there is poor air circulation or drainage. Most spots are only a few inches in diameter; however, under favorable environmental conditions and mowing heights greater than two inches, individual spots may exceed 6 inches in diameter. Affected plants within the diseased spots wilt and eventually turn tan or brown. During outbreaks of the disease, numerous spots on the turfgrass coalesce into large irregular dead areas. This can result in substantial damage to the turfgrass.

 

On individual infected plants, leaves develop light yellow to tan lesions with reddish-brown borders. On cool-season grasses, such as tall fescue and Kentucky bluegrass, lesions normally are located near the middle of the leaf and extend completely across the leaf blade. The bleached area is bordered by dark red to brown margins or lines, which are characteristic of dollar spot. On warm-season grasses (Bermuda grass, buffalo grass, and zoysia grass) the bleached zones on leaves may be more numerous and smaller but are still bordered by brown bands. In the early morning when dew is still present on the turfgrass, small cottony strings of the fungus can sometimes be seen growing from the diseased leaf blades. This growth can be confused with spider webs, “cotton” from plant seeds, or other fungi, and therefore is not a reliable diagnostic feature.

 

The fungi which cause dollar spot survive indefinitely in thatch and soil. In the presence of a thin film of moisture on leaves and favorable temperatures, these fungi will begin to grow and infect leaves. The fungus apparently does not infect the roots, although toxins produced by these fungi may affect root formation. Dollar spot is most severe in late spring and early summer and again in early fall, however it can occur throughout the summer months.

 

The presence of dollar spot often signals an improper fertilization program since the disease is more severe in nitrogen-deficient turfgrass. One of the simplest methods to reduce or avoid dollar spot is to maintain an adequate nitrogen fertilization program. Don’t overfertilize, since this can result in an increase of other turfgrass diseases, such as brown patch. Consult Extension publications on lawn fertilization for more complete information. Avoid night watering or other irrigation practices which allow the leaves to remain wet for long periods. Fungicides are rarely necessary for home lawns and are therefore not recommended.

“What to do about Marijuana?”

0

There are so many questions. Is it safe? Does pot smoking lead to the use of hard drugs? What is the risk of pot smoking during pregnancy? Does marijuana have medical value in treating disease? Does smoking pot relieve the side effects of cancer treatment?

On each of these questions we have information – and lots of opinion. The reality is that on none of these questions do we really have clear cut answers. In spite of decades of experience there is still a serious shortage of reliable, scientifically valid research on the effects of marijuana on the human body.

This deficit has resulted primarily from two factors. First, marijuana has been classed by the government as a Schedule I drug, meaning that it does not have a legitimate medical use (same category as heroin and LSD). This means that it has not been readily – or legally – available to medical researchers who are interested in trying to answer these questions. Secondly, the pharmaceutical industry has not shown interest in trying to develop marijuana into a traditional prescription medication.

So what is the public to do, especially when the issue of legalization” is on the ballot?

Regarding safety, the impression among the public has been that marijuana is relatively safe, safer than alcohol and tobacco. Today we are learning, however, that such impressions are largely unreliable. This is partly because the marijuana on the market today tends to be significantly more potent than what was previously available. Furthermore, studies are emerging which show that risks are greater than previously recognized. The American Heart Assn. recently published a survey showing marijuana use, especially prolonged use, may be associated with an increased risk of both heart disease and stroke. An article in the Journal of the American Medical Association in 2023 showed that marijuana use during pregnancy, especially if continued throughout pregnancy, was associated with adverse outcomes.

What about medical” marijuana? As a physician with 40+ years of experience, my impression is that there probably are some medical benefits from the components in marijuana. The problem, and it is a major one, is that here again we have an abundance of claims and very little good science on which to evaluate those claims.

How do we put all of this together? Bottom line – marijuana use may well have some benefits but there clearly are risks – risks that are being more clearly defined and are probably greater than previously appreciated. As all too often happens, the politics has gotten ahead of the science.

KU School of Business gift creates scholarships for former Summer Venture in Business participants

 

LAWRENCE – A gift from University of Kansas alumna Rebecca Lyons will provide scholarships for School of Business students who have participated in its Summer Venture in Business program.

The program invites high school students who are underrepresented and/or potential first-generation college students to KU’s Lawrence campus to explore business topics and academic resources. The newly established scholarship fund will provide support to enrolled undergraduate KU Business students who participated in Summer Venture in Business.

Lyons, who graduated from KU with an accounting degree, worked for more than 30 years with Johnson & Johnson (J&J). She started out in a finance role and over the years held positions including plant manager, call center manager and eventually became a vice president of supply chain operations.

She also participated in J&J’s leadership development programs and, as she rose through the ranks, helped lead the Finance Leadership Development Program. Additionally Lyons led a global team that established the company’s Global Operations Leadership Development Program. She credits the mentorship and support she received from these programs with instilling in her a desire to help connect others to personal and professional development opportunities. That same mindset inspired her scholarship gift.

“I hope that this scholarship will help give a leg up to deserving students,” Lyons said. “In addition to wanting to help underrepresented students, I appreciate knowing that there’s an infrastructure in place at the school for these students to receive guidance and support. In addition to wanting to help students pay their tuition, I want to see them be successful.”

The school’s Impact Programs staff oversee the Summer Venture in Business, among other programs that provide mentorship and professional development opportunities to School of Business students. This summer marks the eighth time the school has offered the program.

“This scholarship provides students who first connected with our school through the Summer Venture in Business program with a boost of support,” said Paige Fields, KU School of Business dean. “We are grateful for the assistance and encouragement this gift will provide in students’ pursuit of a KU business degree.”

The scholarship covers the cost equivalent to in-state tuition for either one School of Business student with academic merit, or the amount can be divided among a few. Three students will receive support from the scholarship fund this fall.

Lyons said she hopes her gift encourages others to consider giving back, whether through financial support, mentoring or other engagement opportunities.

“It’s not for me to say how or when people give back, but I hope that the people who have an opportunity to do so will in some way,” she said. “My gift is a result of me having received opportunities and mentorship, and I hope it helps perpetuate a cycle of giving.”

Audio-Reader programs recognized by International Association of Audio Information Services

 

LAWRENCE — Audio-Reader Network, an audio information service for blind, visually impaired and print-disabled individuals based at the University of Kansas, has been recognized for excellence in its programming by the International Association of Audio Information Services (IAAIS) at its annual conference, hosted virtually June 12-14.

An audio production of the city of Lawrence’s Outdoor Downtown Sculpture Exhibition brochure won a Program of the Year Award in the Consumer Information category, and two other Audio-Reader programs received honorable mentions.

In the Consumer Information category, volunteer Tracy Harrison voiced the now award-winning audio tour of the sculpture exhibit. Harrison has been an Audio-Reader volunteer since 2015 and regularly reads the Reader’s Digest and Saturday Post program. The annual Outdoor Downtown Sculpture Exhibition was founded by Jim Patti in 1987 and is sponsored by the Lawrence Cultural Arts Commission.

Steve Grimm also started volunteering for Audio-Reader in 2015 and voiced a production promoting Audio-Reader’s audio description events that was recognized in the Now Hear This category.

Originally an Audio-Reader volunteer since 2018, Martha Kehr became outreach coordinator in 2023 and hosts the “Good Works in the Heartland” podcast for Audio-Reader. The podcast’s November 2023 Medicare Open Enrollment episode with Lori Phillips from the Senior Resource Center for Douglas County was awarded an honorable mention in the Interview category.

All programs were engineered and produced by Nick Carswell, Audio-Reader program manager.

The IAAIS program awards were created to promote quality programming among audio information services and to showcase the variety of programs available on audio information services. Entries are judged by staff and volunteers of member stations. Points are awarded for production values as well as pace, timing and vocal quality. An honorable mention is a point or less between first and second place.

Outgoing IAAIS President Maryfrances Evans said, “We are so fortunate to be surrounded by such talented volunteers and dedicated staff to bring the printed word to life to thousands of print-disabled people throughout America. These awards highlight some of the extraordinary programs reading services around the country are producing.”

Most states offer a radio reading service similar to Audio-Reader. A full list of the over 70 available services is on its website.

New work highlights physical, mental, social benefits of caring climate in sports

 

LAWRENCE — The story is often told of athletes or coaches who consulted a sports psychologist to help overcome an obstacle to their success on the field. A University of Kansas researcher has contributed to a new edition of a book on psychology in sports detailing years of work showing that when athletes perceive a caring climate in their sport, the benefits show up from the field of play to mental, physical, social and other areas of their lives.

Mary Fry, professor of educational psychology at KU, has long studied a caring, task-involved climate in sport, where the focus is on supporting athletes, caring for them as individuals and encouraging fun and growth instead of placing emphasis on competition and punishing mistakes. She reflects on the research, benefits of a caring environment and how coaches can implement it in a chapter in the new book “Social Psychology in Sport” second edition, edited by Louise David of Umea University in Sweden, Richard Keegan of the University of Canberra in Australia and Sophia Jowett of Loughborough University.

“Writing a review chapter like this gives you a chance to reflect on the work you’ve done, reflect on where we are at, where we’re moving and research directions coming up,” Fry said. “We’ve done almost 20 years of research on caring climates, but it’s still one of the newer areas in motivation. We had a chance here to focus on what we’ve found about the good outcomes when coaches and athletes perceive a caring climate.”

The chapter, written with co-author Lori Gano-Overway of James Madison University, examines those outcomes in detail. Fry and colleagues’ research has shown numerous benefits of a caring climate in social behaviors of athletes, including liking their teammates more, feeling a sense of belonging, compassion for peers, social self-esteem and more prosocial and caring behaviors. In keeping with the book’s theme on sport psychology, Fry’s work has found psychological well-being outcomes such as increased sense of hope and happiness and ability to regulate positive and negative emotional responses.

A big part of any coach’s job is to motivate players, and Fry and Gano-Overway detail findings of increased effort among athletes in the caring climate as well as commitment to continue playing and continued participation in the future. The latter is especially important in youth sports as large numbers of young people decline to continue with a sport at each increase in age ranges, Fry said.

Mental and life skills and physical health have also been positively associated with the caring climate, as studies have shown athletes have improved coping skills, more mindfulness, confidence in their ability to explore future careers after sport, an increased willingness to share concussion symptoms with coaches, increased care for their physical health and returning to play only when fully healed from concussions.

The benefits of a caring sport climate may seem like they should be intuitive, yet an ego-driven climate is often the default, Fry said. And criticism of the approach often claims it is soft or not as likely to be successful in terms or performance or wins and losses. However, study results have shown that when athletes perceive they are in a caring climate, they record more assists, commit fewer turnovers, are more motivated and more likely to feel they reached their full potential during the season.

“It simply makes sense that a climate that makes you feel safe and comfortable in which you’re not afraid of making mistakes enables you to be able to perform better,” Fry said.

In addition to detailing the benefits of a caring climate, the chapter helps detail how coaches can implement the practice with their own teams. By helping coaches understand the theoretical and conceptual underpinnings of why the approach works, the authors also share practical advice on how to tailor the approach through personal and situational factors that will vary by sport, team and athletes taking part.

Fry and Gano-Overway’s chapter is one of four in “Social Psychology in Sport” dealing with motivational considerations. The book also has parts dedicated to relationships in sport, leadership, key social and cognitive processes and the athlete in the wider sport environment.

While results have consistently shown benefits for athletes and coaches, the authors close their chapter discussing future directions for research. Much of the work thus far has been done in a laboratory setting, or with a relatively small number of coaches. Upcoming work will detail how a caring climate implemented throughout a school district with all coaches and teams can be done and what benefits it may have. Other research will examine how an individual’s personality type influences benefits of a caring climate and how interventions can be designed to help coaches and athletes.

“Even in the short interventions we’re seeing compelling results,” Fry said. “What’s of greater interest now is focusing on interventions in the ‘real sports world’ to gather data on results with athletes in this environment and connecting it with coaches in pre and post designs.”

Nicodemus descendent, historian to speak at KU Libraries on July 10

LAWRENCE — Preserving and promoting the history of the nation’s longest-standing Black homesteader colony is a personal passion for Angela Bates, founder and executive director of the Nicodemus Historical Society. A descendant of the original settlers of the town of Nicodemus, Bates has worked for over 30 years to honor the Kansas community’s legacy, establishing regional and national partnerships including collaboration with KU Libraries and the Kansas Collection.

Bates will give a special presentation highlighting the history and significance of Nicodemus at 1 p.m. July 10, in Spencer Research Library’s North Gallery.

“I hope one day that everybody will know where Nicodemus is and what it stands for nationally,” Bates said. “Too often we look at American history and focus in, in particular when it comes to African Americans, on the slave experience and the atrocities as a result. Then we jump right out of that into the Civil Rights Movement, but we skip over what happened to African Americans right after emancipation and coming out of the Reconstruction Era. That whole chapter is just missing, and people don’t know about it, so I’m hoping through the story of Nicodemus they will understand what African Americans did with their freedom.”

Nicodemus was founded in 1877 by African Americans who migrated from the southern United States shortly after the Civil War. Both of Bates’ parents were from Nicodemus, directly descended from its original settlers who filed homestead claims, seeking better land and opportunities as well as refuge from the Reconstruction-era South. The homesteaders established farms and homes and the county’s first public school, with town leaders rising to prominence in state politics.

Bates has helped establish a collection of thousands of historic photographs, documents, diaries and more reflecting the history of Nicodemus and its settlers. A basement flood in the home of Bates’ cousin, where hundreds of historical photographs had been stored, was part of the impetus to work with KU Libraries to aid preservation and provide easier access to materials for researchers and the public, efforts facilitated by ongoing connection with KU Libraries’ African American Experience Collection curator and field archivist Deborah Dandridge.

“Our African American Experience Collections are proud to serve as a partner with the Nicodemus Historical Society during these last 30 years,” Dandridge said. “We look forward to continuing to preserve and process these resources that document a premier cornerstone of Kansas history.”
