Ornamental PGR Guide

This database lists rates for Fine Americas PGRs, when available, and includes recommendations from leading university researchers and other published sources, as well as from plant suppliers and growers. Spray rates listed are recommended as applications at the label-recommended volume of 1 gal. per 200 sq. ft. unless otherwise stated. Use the rates listed as starting points for your own PGR trials.

Note: Not all uses are listed on the label, so check the product label before using. Consults product labels for a complete listing of precautions and recommended use rates. When using any PGR for the first time, always test the rate on a few plants and compare the results to untreated plants before treating an entire crop. Keep in mind that Sunbelt growers use higher rates than Northern growers.
