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,…

I’ve had a few calls this week on Desirable leaf drop. While mowing orchards all week, I noticed some of this myself. Upon closer examination, where I was seeing it from the tractor it seemed to be only on trees which had stopped up microsprinklers. What appears to be going…

It’s that time again to be mindful about pecan nut casebearer (PNC) activity especially after the infestations reported by some growers last year.

It’s too late to help us for this year, but there is a new fungicide labeled for pecans that provides a totally new chemistry for us to use in our arsenal of weapons to fight pecan scab and its performance on nut scab in UGA Plant Pathologist Dr. Tim Brenneman’s…

Its time to crank up the irrigation in pecans orchards as shell hardening is completed and kernel filling begins. All irrigation systems should be at full capacity from now through mid September in orchards bearing a commercial crop. This means 3600-4000 gal/acre/day for drip and micro-sprinkler systems and 1.5″-2″ per…
