Cotton PGR Rainfastness

Cotton PGR’s have been going out across the region now for a few weeks and many of you have asked about the rainfastness of these products.  I encourage you to always check the label of the specific product that you are using but below are some general guidelines you can use to make sure that the PGR’s you apply are making it into the plant.


Thanks to UGA Extension Agronomist Dr. Guy Collins for this information.  If you have any questions, contact your local county agent for more information.
