Abstract: The objectives of this project were to a) evaluate an experimental plant growth regulator (PGR) for reduction of grass biomass in comparison with an industry standard PGR in golf course turf (creeping bentgrass/Poa annua mixture at 9 mm fairway mowing height), and b) to determine appropriate rates for experimental PGR competitive to the industry standard rate and to evaluate crop safety on turf. The trial involved established creeping bentgrass/annual bluegrass fairway type turf on sandy loam soil. Treatments consisted of the sponsor's product at several rates applied monthly. An untreated check as well as an industry standard treatment was also included. Color response and general vigor of the turf was assessed using canopy reflectance (chlorophyll meter or Greenseeker NDVI and R/NIR). No growth regulator treatments produced a consistent reduction in shoot tissue growth relative to the untreated check, and in fact on many dates the growth rate in treated plots was greater than in the untreated control. This differs from the previous year, when there were some slight decreases in growth detected in some treatments. None of the treatments had a negative effect on turf color or quality (assessed by canopy reflectance and visually).
