The University of Georgia and USDA-Byron research scientists are collaborating in a project entitled, “Pecan Hedge-pruning: A Sustainable Management Option for the Southeastern US”. The project will assess the effects of pecan hedge-pruning on critical horticultural parameters (nut yield, quality, water-use efficiency, and nutrition), disease (incidence and severity of scab, colonization of branches by wood…

Based on conversations I have had with a number of growers it sounds as if there is a need for some clarification regarding phosphite materials. Phosphite has become a very valuable tool for us in the battle against pecan scab. Dr. Tim Brenneman first began testing phosphite materials on pecan primarily for efficacy on some…
