Efficacy of experimental plant growth regulator on biomass growth reduction in creeping bentgrass fairway type turf

The following study evaluates an experimental plant growth regulator on creeping bentgrass in comparison to Primo MAXX on golf course turfs. The optimum rate for the experimental PGR was tested for as well as an evaluation on crop and turf safety. After initial treatment, there was a significant decline in the uniformity and quality of the turfs that received treatment. The decline was attributed to the response of treatment in the mix of creeping bentgrass, altering the colour. Overall all treatments resulted in a decrease in shoot tissue growth. With significant differences in the high rates of PGR at 0.28 and 0.56 kg ai/ha, reducing growth by 68 to 76% during the trial. The smallest deviation in normal plant shoot growth came from the lowest rate PGR; reducing the growth rate by only 34%. BASF Corporation
