Dan Anco Clemson Comments Peanut Notes No. 74 2022

Attached are a few peanut pictures from the field. Also included is the across-year and within-year outputs for near Blackville from the NC State thrips model. The model makes predictions for individual locations. A quick look shows areas near Florence just now entering into the high risk period for thrips injury, whereas near Blackville it is beginning to slowly exit the high risk period (about a week difference). Depending on in-furrow insecticide choice and planting date, keeping an eye on early thrips injury and considering an early post-emergence application of acephate can help to reduce severe thrips injury from overlapping with paraquat injury. Thrips injury alone can reduce yield and set the crop back from growing and closing the row, and when this is combined with paraquat injury the loss is much more severe, particularly when bentazon/Basagran is omitted from the paraquat application.


Mole crickets usually are not an economically important pest in peanut.
