This episode features Dr. Wendell Hutchens, assistant professor of turfgrass science at the University of Arkansas, discussing his research on turfgrass disease management, particularly spring dead spot control. The conversation covers his educational background at NC State and Virginia Tech, where he worked on fungicide fate and movement in soil profiles. Dr. Hutchens explains that effective spring dead spot management requires immediate watering-in of fungicides within 30 minutes of application to move products into the root zone where pathogens are active. He details how GPS-guided sprayers combined with drone mapping can reduce fungicide usage by 40-65% while maintaining control efficacy by targeting only affected areas. The discussion also explores cultural management practices like thatch reduction, nutrition management with manganese and nitrogen sources, and the economic impact of the disease on golf courses. Additionally, they examine the USGA's GS3 ball technology for measuring putting green quality, including smoothness and trueness metrics, and how surface disruptions from aerification and foot traffic affect ball roll for extended periods.

Frank catches up with F. Dan Dinelli, recent inductee to the the Illinois Golf Hall of Fame and third generation golf course superintendent at North Shore Country Club in Chicagoland. Dan and Frank catch up on the putting surfaces that were renovated in 2017 to a creeping bentgrass blend and an innovative root zone mix with 33 ingredients! Dan and Frank review the complex nature or plant and microbe interactions that have led to a better understanding of root zone dynamics in sand based root zones. Hold your breath as this one is a deep dive. Big congrats to Dan on being a HOFer.

In this episode of the Renovation Report, sponsored by Golf Preservations and CapillaryFlow, Brandon Johnson talks about his entry into the game playing as a child and how that led eventually to a successful career as a golf course architect. A graduate of North Carolina State University, Johnson also earned a master's degree in landscape architecture from Harvard University. Johnson discusses how his time as a student at NC State prepared him for continuing his education at Harvard, and how postgraduate studies in the Ivy League provided unique experiences that he probably would not have been exposed to otherwise. Some of those experiences include working at the PGA Tour Design School, being the lead architect for the First Tee program and study-abroad opportunities in locations such as England, France, Italy and Switzerland and how each helped form his career that includes learning under Arnold Palmer and Ed Seay.

Bradley S. Klein, Ph.D., talks with golf course architect Stephen Kay of Kay Golf Course Design about their friendship that dates almost 40 years, and how it intersects with the changing face of municipal golf in the United States. In this discussion, sponsored by Golf Preservations and CapillaryFlow, Key discusses how and why the majority of the design and renovation jobs have changed from mostly private to about 70 percent municipal projects. The discussion includes how many municipalities have changed the way they view their golf course properties, and how golfers who patronize them are more savvy about the game and course conditioning than in the past. Finally, the discussion addresses the importance of regular communication with superintendents and local officials during municipal design and renovation projects for numerous reasons, that include building a course that can accommodate beginners without alienating low-handicap players, as well as differences in how private and municipal properties are maintained. For example, areas around tees must be larger because they are subject to excess wear and because triplex mowers are used to maintain them. The area around greens must also be larger to give boom sprayers room to turn.

In this episode Frank visits with Professor Ming Yi Chou, Turfgrass Pathologist at Rutgers University, former sommelier, and expert microbial molecular biologist. He earned his B.Sc. from National Taiwan University, M.Sc. from the École Supérieure de Commerce de Dijon, and Ph.D. in Horticultural Biology from Cornell University, followed by postdoctoral work at the University of Wisconsin–Madison and Michigan State University. His research explores plant–soil–microbiome interactions, develops disease-prediction models and diagnostic tools, and directs one of the nation’s largest turfgrass fungicide evaluation programs. Widely recognized for his contributions to science and extension, Dr. Chou received the 2024–2025 Merle V. Adams Award for outstanding achievement as an assistant extension faculty member.
