Wick Applications to Control Large Palmer Amaranth Peanut Notes No. 75 2018
We are approaching a time when pigweed escapes will be an issue. When plants are very large, a wick application of Gramoxone SL can work well. See page 64 in 2018 Peanut Information for details. Coverage of at least 60% of the plant is needed for acceptable control. Avoid contact with peanuts.
