  • Late July Pecan Notes

    I was seeing water split on Pawnee over the weekend, which is a sign they will soon be at shell hardening. I suspect that will occur possibly by the end of next week. This means we are looking at probably one more fungicide spray on Pawnee to get them through. Most other varieties will need…

  • Young Trees Crashing

    Since late May, I’ve seen a number of trees between the ages of 2nd and 4th leaf suddenly crash. The leaves remain on the tree after turning completely brown. All of this is during the dry and hot spell. It is essentially as if something is clogging the vascular system in which the leaves starve…

  • Mid-Season Status of Georgia Pecan Crop

    Last week, the Tri-State Meeting estimated the current Georgia crop at 130 million lbs. I don’t know if that is wrong or right. It is nearly impossible to put a number on Georgia’s crop because the calibration of its size is in such a state of flux. We have acres of trees coming into and…

Most everyone is familiar with the species that causes warts on the leaves referred to as Leaf Phylloxera. Tiny, soft-body, aphid like insects feed…

The adult moths of this species emerge out of their overwintering stage in the spring and are often active in pecan orchards from mid-April onwards. No…

  • I’ve had 5 calls in the last 6 days about orchards hit by either 2,4-D mix drift or volatization from adjacent row crop fields being burned down in preparation for planting. The most common mix has been 2,4-D, Glyphosate and Flumioxazen. The 2,4-D shows up as twisted or curled leaves, the glyphosate as thin, strappy…

  • Pre-Emergent Herbicide Rotations

    Among many other things to do in the orchard, now is also the time to start our pre-emergent herbicide programs for the spring. With the price of glyphosate and glufosinate increase in 2021, I began working with pre-emergent herbicides for pecan at the Vidalia Onion Research Center. Though post emergent prices have come down some,…
