Wintertime Stress among Golf Course Superintendents: Identifying Environmental Triggers and Anticipatory Responses

Michael R. Barnes, Eric Watkins, Kevin W. Frank, Bryan C. Runck et autres

Wintertime management presents a significant risk to turfgrass and other horticultural systems, yet the psychological impact of these environmental uncertainties on managers and growers remains poorly understood. The impact of psychological stress can have impacts both on the individual and implications for …

Comparing the effects of soil test interpretations for P and K on a creeping bentgrass putting green

Jackie Lyn A. Guevara, Payton C. Perkinson, Kevin W. Frank

Abstract Soil testing provides golf course superintendents with the information needed to apply fertilizers at optimal rates, thereby avoiding nutrient deficiencies and unnecessary applications. However, nutrient rate recommendations vary depending on how soil test results are interpreted. Two approaches to interpreting soil …

Maximizing seedhead suppression of Poa annua L. in Michigan through use of growing degree‐days to predict optimum application timing for ethephon and ethephon plus trinexapac‐ethyl

Ronald N. Calhoun, Kevin W. Frank, Aaron D. Hathaway

Abstract Research was conducted from 2002 to 2006 to determine optimum application timings for the chemical seedhead suppression of annual bluegrass (AB) [Poa annua L. var. reptans (Hauskins) Timm.] by single applications of the plant growth regulators ethephon (EP) (2‐chloroethylphosphonic acid) or …

Using local weather stations to generate growing degree‐day data to predict the flowering pattern of an annual bluegrass fairway in Michigan

Ronald N. Calhoun, Kevin W. Frank, Aaron D. Hathaway

Abstract Six 1‐yr observational studies were conducted from 2001 to 2006 at the Hancock Turfgrass Research Center in East Lansing, MI to characterize the timing, duration, and amplitude of annual bluegrass (AB) (Poa annua L.) seedhead emergence in a 10‐ to 15‐yr‐old …

Regional Roadside Turfgrass Testing Program

Eric Watkins, Jon M. Trappe, Kristine M. Moncada, MARK J. RENZ et autres

Roadsides are a challenging environment for successfully establishing turfgrass. Site-specific stresses demand multi-site testing of grasses and grass mixtures. This study evaluated 60 entries that varied by cultivar, species, or mixture by establishing on-site trials in MI, MN, NE, NJ, and WI. …
