Respose of cool-season turfgrasses to a new plant growth regulator

Plant growth regulators (PGRs) are a useful tool for turfgrass management. Plant growth regulators have been used for many years to manage turf grass, with the goal of reducing mowing frequency and achieving the best visual score . The aim of this study was to investigate the efficacy of the PGR Primo Maxx II and ATTRAXOR on reducing the vertical growth of Lolium perenne /Poa pratensis turfgrass and Poa annua seedhead formation. The results of this study demonstrated that the ATTRAXOR can perform well or at par with the already available plant growth regulator Primo Maxx II. The trial included the parameters like, color, quality, NDVI, germination, daily growth rate, temperature, precipitation and biomass. The experiment was conducted over a period of 2 years, comparing the ATTAXOR and Primo MAX II from March 2023 to March 2025. This study provides valuable insights into the performance of the Plant Growth Regulator (PGR) ATTRAXOR during the spring and fall season. The results showed that the treatments had a significant impact on the Lolium perenne /Poa pratensis turfgrass and Poa annua seedhead formation, as indicated by the statistical analysis.
