This time of year county agents and consultants receive questions about PGR management in cotton. Below is a chart, from Dr. Jared Whitaker UGA Cotton Agronomist, that is designed to assist growers with PGR applications in cotton from a variety standpoint. Many factors are associated with PGR strategies other than variety and should be considered before utilizing this chart. However, research has indicated that the varieties listed in each of the classifications (1-4) have similar growth patterns and potential and respond similarly to PGR strategies. Therefore, this information can be critical to managing new varieties for producers.
