Abstract

Plant growth regulators are compounds applied on golf courses to control turfgrass height. This study compared Anuew (active ingredient prohexadione-calcium) and Primo Maxx (active ingredient trinexapac-ethyl) as plant growth regulators on a mixed-stand fairway of creeping bentgrass and annual bluegrass. Visual ratings and NDVI readings were taken as measures of canopy quality and colour on a weekly basis. Fresh weight and dry weight clipping collections were taken every 350 GDD as measures of plant biomass. Visual ratings and NDVI readings showed some significant differences between treatments and control. Clipping biomass (fresh weight and dry weight) showed significant differences between the control and the treatments but there were no significant differences between the two treatments. As the rate of application of Anuew increased, there was less clipping biomass. Anuew and Primo-Maxx performed similarly as they both effectively regulated the growth height of the mixed-stand fairway. Nufarm, Guelph Turfgrass Institute
