Some folks find themselves with no or very little residual herbicide in place with peanuts already up. If weeds are small, paraquat plus Basagran plus a Group 15 residual herbicide is a good option. You can add another Group 15 for your next spray with Cadre, Cobra, Storm, Ultra Blazer, Basagran, and Clethodim products. If weeds are large, you need to shift to the “next spray” list. Grasses can be controlled easily with clethodim products, especially with the good moisture we have right now. Use 8 to 16 ounces of product. Applying clethodim products at least 3 days before contact herbicides really helps optimize control. If you need to tank mix herbicides because of logistics, apply 16 ounces of clethodim products. This may not give complete control but you can follow up when regrowth appears.

Although we have not looked at all combinations, acephate can be tank mixed with all of the herbicides listed above if you need to control thrips. Make sure there is only minimal injury from thrips before you apply paraquat. Radiant SC is being sprayed by many farmers concerned about acephate resistance in thrips. We plan to do some work this summer making sure Radiant SC does not increase herbicide injury.

Cadre is also a good option (consider rotation restrictions before you apply Cadre or Impose.) If you have Palmer amaranth, you likely have an ALS resistant biotype (or at least a significant portion of the population.) You will need to apply Cobra or Ultra Blazer at 12.5 oz. or 24 oz., respectively, with Cadre/Impose to control the resistant individuals.
