Abstract/Contents: | "Plant growth regulators (PGRs) have been evaluated and used on turfgrass since the 1940's. Until the development of new PGRs in the 1980's and 1990's, their use was limited to turf areas where phytotoxicity was not a concern. Plant growth regulators slow turf growth and development by either stopping cell division in meristematic regions (Ex.-maleic hydrazide or mefluidide) or by interfering with gibberellin (GA) biosynthesis (Ex.-paclobutrazol, flurprimidol, and trinexapac-ethyl). Cell division inhibitor PGRs have been referred to as Type I PGRs, and those that interfere with GA production early in the biosynthetic pathway. Paclobutrazol is widely used to reduce Poa annua. Trinexapac-ethyl (Primo®) is foliarly absorbed within one hour and interferes with GA production late in the biosynthetic pathway, primarily at the conversion of GA20 to GA1. Primo (Class A) is a cyclohexadione that represents a new chemical class of PGRs. It was first synthesized in the laboratories of CIBAGEIGY Limited, Basic, Switzerland in 1983, and registered for use in 1993. It is effective in managing the growth of all the major turfgrasses, especially in highly maintained areas such as golf courses and sports fields. Plant growth regulators are used primarily to reduce clippings and mowing. Their cost can be offset with savings in labor and increased equipment life. Other benefits include improved turf color, increased turf density, increased rooting, increased green speed, consistent green speed thoughout the day, less scalping, better water utilisation, enhanced overseeding establishment, better divot recovery, and improved stress tolerance. Primo is the first PGR that is primarily recommended for use on high maintained turf. Research is being conducted in areas previously evaluated with other PGRs whose findings were not successful or were cost prohibitive. Additional potential areas of PGR use include speeding establishment time from seeding and vegetative planting of turf, increasing sod tensile strength, increasing food reserves and stress tolerance, and others. Plant growth regulators allow turf managers to manage the growth of turf and improve its quality, and their use should continue to increase." |
