It is an important time of the production season for pecan producers.
Lenny Wells, University of Georgia Extension pecan specialist, noted in the UGA Extension Pecan Blog that growers need to be aware of the time sensitive task of leaf sampling. The leaf sampling period runs through Aug. 7. It’s the period when nutrients are most stable in the leaf. This task is the only way for pecan producers to know the fertility status of their trees. Along with a soil sample, farmers can plan their fertilizer programs for the following year.
“Therefore, do not forget this important task,” Wells wrote.
Weather Challenges
Persistent rains have wreaked havoc with growers trying to keep trees sprayed regularly. Wells recommends at least five to six hours of drying time but admits that may not always be feasible.
“If you are caught by rain, go back and respray anything not dried on for at least an hour, and then plan on tightening up the spray interval for the next spray,” Wells added.
Additional Fungicide Sprays
Wells added that most varieties, other than Pawnee, will require at least two more fungicide sprays. In an orchard where scab is rampant or with a variety that’s highly susceptible to scab, three more sprays are needed, if the current weather pattern continues.
