Cool-season turfgrass reaction to a newly developed plant growth regulator.

Plant growth regulators (PGRs) are Turfgrass Management Agents that have a very significant impact. They mainly serve to cut down on mowing and enhance the grass's overall attractiveness. Through the years, PGRs have been used to keep the grass healthy with the main focus on the attractive look of it. The objective of this research was to compare the effectiveness of two PGRs, Primo Maxx II and ATTRAXOR, in reducing vertical growth in Lolium perenne/Poa pratensis and controlling the seedhead development of Poa annua. The findings of the research indicated that ATTRAXOR was equal to the effect of Primo Maxx II, a common PGR used for turf. The experiment determined parameters like turf color, turf quality, NDVI values, germination rates, daily growth patterns, and environmental factors such as temperature, precipitation, and biomass production. The experiment compared both PGRs in the spring and fall seasons. Results revealed that the treatments had a notable impact on the growth of Lolium perenne/Poa pratensis and the suppression of Poa annua seedheads.
