honey dew and sooty mold covering their leaves as compared to the leaves of all other cultivars in the trial. I'm not suggesting that Gardner is resisitant to aphid feeding because I saw definite signs of aphid feeding on the leaves. However, less honeydew on the foliage indicates that fewer aphids were feeding on these Gardner trees.
In future years, I'll need pay particular attention to how Gardner fares during an outbreak of black-margined aphids.
Gardner is similar to Pawnee in terms of ripening date and the nut even looks a lot like Pawnee. However, Gardner nuts appear more round in cross-section as compared to the more flattened Pawnee. Also like Pawnee, Gardner has a protandrous habit and is susceptible to pecan scab. Fortunately, scab did not appear to be a problem for any of cultivar in our trial this year.
