PGR Guide for Annuals is available

The new 2023-24 Plant Growth Regulator (PGR) Guide for Annuals is now available from Fine Americas Inc.

“For decades, Fine Americas’ technical specialists and university researchers have partnered to find solutions for ornamental growers’ challenges, and what we heard consistently was that growers wanted a way to easily and readily access that information,” says Greg Johnson, president, Fine Americas Inc. “That’s why for nearly a decade, we’ve produced the guide alongside GrowerTalks, to deliver growers the information they demand.”

The newest annuals guide includes tips for using ancymidol on plugs; growth control for super-charged succulents; improved rooting with a new IBA; information on using PGRs for some unexpected benefits like better water utilization, disease suppression and greener color; and more. Researchers from North Carolina State University, Virginia Tech and The Ohio State University contributed their expertise.

The product-by-product guide to all ornamental PGRs is updated and expanded, thanks to Brian Whipker of North Carolina State University, and the guide also includes a handy dilution table to help growers with measurement and application calculations.
