Pecans have set their nut crop for 2026. I have started to see some PNC damage in orchards. We have begun to receive some sporadic rainfall at the end of May, and as we know this increases our risk of scab. Hopefully by now you have had atleast 1 spray on low scab potential varities and atleast three sprays on high scab potential varities. For pecan scab spray guides based on variety see the “Mature Pecan Management” slides. Be sure you are subscribed to the UGA Pecan Blog to receive timely updates from the UGA Pecan Team
Will Brown’s Tips for June
- In June we should begin to irrigate more than we were in April and May. Irrigate 3 hours per day. If you receive 1” or more of rain, turn the system off for 3 days.
- Apply the following 1/3 of your annual nitrogen rate if the crop load is good.
- Check for mouse ear and pecan rosette, apply zinc and/or nickel sprays to affected trees.
- Scout for aphids (Consider applying imidacloprid in drip if you have Sumner/Schely/Gloria Grande). At this point it is too late to consider an insecticide application for Pecan Nut casebearer.
- Continue fungicide sprays, on high scab potential varities spray ever 10-17 days (reduce interval to 10 days if rainy, extend to 17 days if dry), on moderate scab potential varities spray ever 14-21 days (reduce interval to 14 days if rainy, extend to 21 days if dry).
