Though thrips pressure has not been particularly high in 2023, it doesn’t take many adults per plant to produce a damaging population of immatures on peanut. Thrips injury typically peaks around 28…

Peanut planting time has arrived in Georgia, and that means thrips season is here as well. Many of the decisions a peanut grower makes at planting will affect the risk of thrips infestation and the risk of Tomato spotted wilt disease.

The most damaging pest of peanut in Georgia is the lesser cornstalk borer (LCB), and while it does not disappear when rainfall is plentiful,…

Georgia peanut growers need to scout their fields this week for tobacco budworm. Infestations of this pest have been on the rise in peanut over the last fourteen days, and it does not take a lot of budworm caterpillars to cause significant defoliation when the crop is less than 50 days after emergence.

If you have been walking or riding through peanut fields in Georgia over the past week you have almost certainly noticed fields with thrips injury, or as some of my colleagues say, “thrippy peanuts”.

Several folks have contacted me this week about large numbers of white-lined (aka white-margined) burrower bugs. Most of the bugs have been on volunteer peanuts, but some were on cotton seedlings. This insect is not the “peanut burrower bug” and is not considered a pest of peanut. While it can be very abundant early in…
