| Abstract/Contents: | Profiles trinexapac-ethyl, "the active ingredient in Primo Maxx," explaining that "among other benefits, researchers have shown Primo application increases turf color and density, heat and drought tolerance, and shade tolerance." Suggests that "these secondary benefits can often overshadow the most obvious benefit of Primo: reduced clipping production." Discusses growing degree day (GDD) systems, stating that they "are used to predict various naturally occurring events such as the bloom of various plants or the emergence or [of] insects. In turf, GDD systems are widely used to predict the optimum timing for herbicides and Primo/Proxy mixtures to suppress seedheads." Presents an experiment conducted to determine if "establishing [a GDD system] would provide superintendents a method to more effectively maintain consistent growth regulation throughout the growing season." Reports tht "both the 100 and 200 GDD reapplication treatments maintained constant growth regulation during the summer." States that "re-applying Primo every 200 GDD or less will provide consistent growth regulation on a creeping bentgrass putting green. Additionally this reapplication interval will maintain darker green color and higher turfgrass quality." Concludes that the "ultimate goal [by researchers] is to develop a program that would allow turfgrass managers to obtain accurate re-application interval recommendations for a wide variety of agronomic situations." |
