Course Summary:

This course will give a comprehensive look at plant growth regulators (PGRs) and the various reasons for their application on golf courses. The discussion topics include the PGR options available in 2021, the strengths and weaknesses of each PGR, and how PGRs can provide healthier turf on putting greens, fairways, tees, and even roughs. The course will also cover how PGRs can be used for long-term control of Poa annua. Golf course managers will also learn how to make informed reapplications of PGRs using growing degree days (GDDs).
