Buffalograss tolerated all herbicide treatments and did not exhibit foliar damage even though temperatures surpassed 80°F unlike previous recommendations. Read more here.
Ethephon (Proxy; Bayer) was mixed with common snow mold fungicides, Interface Stressgard and Mirage Stressgard (Bayer) or Instrata and Banner Maxx II (Syngenta), and applied at two winter timings of pre-snow cover and post-snow melt. This was done to evaluate the compatibility and safety of these mixtures on greens because preceding spring seedhead programs with […]
Four species of turf-damaging billbugs exist in Utah (in descending order of abundance): bluegrass billbug, hunting billbug, Rocky Mountain billbug (or Denver billbug), and Phoenician billbug (or Phoenix billbug). Managing multiple billbug species in turf is more challenging because of differences in the insects’ biology and phenology. The anthranilic diamides, Acelepryn and Ference, have provided […]
Humic substances are often used as an amendment in putting greens to improve turf health, but little is known regarding their effects on soil moisture retention. Commercial humic substance products and pure organic acids were applied to three golf course putting greens in Utah in 2006 and the Utah State University research putting green in 2006 and 2007. These […]
Winter Applications of Plant Growth Regulators Improve Annual Bluegrass Seedhead Suppression Adam Van Dyke, CPAg, MS, Professional Turfgrass Solutions, LLC Author email: email@example.com The use of chemical plant growth regulators (PGRs) in spring is common on golf courses where annual bluegrass (Poa annua) inflorescences (flowers/seedheads) are undesirable. Seedheads negatively impact surface uniformity and […]
The known range of the common crane fly (Tipula oleracea L.) is expanding in the western US, as adults were captured (by me) in Utah while emerging and flying over golf course rough. Adults were collected at The Ridge Golf Course in West Valley City on 15 September, 2014, and identified by Dr. Benjamin McGraw […]
Objectives Determine if applications of Ethephon and Mefluidide applied Pre-snow/winter and Post-snow/winter, along with the combination, and including traditional spring applications will increase annual bluegrass seedhead suppression when compared to the traditional spring application program. Materials and Methods The study was condicted from November 2014 until June 2015 on a putting green at Mountain View […]
