Burndown Rates of Herbicides Peanut Notes No. 30 2018

— Written By

Use the full rate of all herbicides. Lower rates encourage herbicide resistance and inconsistent performance. At this point it is risky to apply a residual herbicide, especially auxins, with glyphosate as a burndown and then plant peanut. The best thing to do is apply glyphosate and then paraquat one week later. This one-two punch can be effective but use the full rate of each herbicide and with paraquat try to get good coverage of weeds. Higher spray volumes, slower ground speeds and smaller droplets increase the likelihood of success with contact herbicides.
