Been getting quite a few phone calls about TSW/BD in peanuts. This particular plant loves wet weather so I am not surprised. Here are few thoughts to consider especially since many of you were not employed by UGA back when TSW/BD was Public Enemy #1.
1. The backbone of all TSW/BD programs has been Dual Magnum. Over the years, Dual Magnum has provided some of the most consistent residual control of this weed. When Culpepper, Flanders, and I were frantically searching for control strategies back in the early 2000’s, Warrant and Zidua were not yet players in this game. Warrant and Zidua have good activity on TSW/BD but I have more data/experience with Dual Magnum.
2. Paraquat + Dual Magnum + Basagran or Storm is an excellent EPOST treatment for the control of TSW/BD, assuming the peanut field is still within the labeled paraquat application window of ~33-38 DAP.
3. If growers miss the paraquat application window, the best POST treatment for TSW/BD is Strongarm. Growers who apply Strongarm POST in peanut need to pay close attention to the labeled crop rotation restrictions.
