Water stage fruit-split of pecan is often a major problem exhibited by thin-shelled pecan varieties (e.g., Schley, Caddo, Oconee, Sumner, ‘Wichita’, ‘Frotcher’, and ‘Farley’) and, to a […]

Some early pecan varieties have reached shell hardening and others are rapidly approaching. This means that the water use requirements of pecan are about at peak demand and will remain so through kernel filling.

Dr. Katherine Stevenson’s fungicide sensitivity testing program is a wonderful service for Georgia’s pecan growers and I would encourage all of our growers to take advantage of this opportunity. It is free to the grower and provides orchard-specific information about the potential risk for scab resistance to the most commonly used fungicides for pecan. Instructions […]
