PGRs a Specialized but Valuable Tool:Landscapers use plant growth regulators to solve unique problems

摘要

The trick in controlling grass and ornamental bushes is to let them know who's boss. Willy-nilly, grow-as-they-please plants do not fit profitably into a 21st-century landscape business plan. One tool to keep plants in line through a growing season isapplication of plant growth regulators, or PGRs.Growth regulators have been around for half a century. Even so, their use by U.S. landscape maintenance companies is hardly universal today. Utilization varies widely between commercial and residential projects, southern and northern regions of the country—even between different generations of professionals."My goal is to get people out there to understand how PGRs work," says Clint Formby, technical specialist with SePro turf and landscape products. "Young guys are working with plant growth regulators more and are starting to understand the labor savings from doing so. It's a fairly new concept."
