AUBURN, JULY 26---During August, pecan trees may need special attention to ensure profitable production of pecans. That's when pecans are reaching fourth nut drop, water-gel stage, shell hardening and early kernel filling, the most critical part of the season.

"If the crop is excessively heavy, mechanical thinning to reduce crop load should be completed by early August," says Dr. Bill Goff, horticulturist with the Alabama Cooperative System.

Pecan weevil, hickory shuckworm, mites and yellow and black aphids also can be a problem in August. Some growers may need to apply fungicide sprays, but applications usually end about mid-August.

Growers also need to check for aphid and mite infestations that frequently build in late August, especially following carbaryl or synthetic pyrethroid sprays. .

Goff advises growers to scout and spray as needed for scab, foliar diseases, mites and aphids. In addition, monitor pecan weevil and shuckworm traps closely. Postemergence herbicides can be applied in August, if needed.

Growers can propogate trees in August by using the patch-bud technique, adds Goff. Keep trees watered, especially in late August and through September, and keep orchards mowed and clean to help reduce pests.
