Cover crops can provide many benefits to peanut and cotton rotations. Especially in terms of suppressing weeds, conserving soil moisture for planting, increasing soil organic matter, and reducing soil erosion. However, in fields where residual herbicides were used during the growing season, residues could impact cover crop establishment.
Studies on daikon radish, cereal rye, cocker oats, crimson clover, winter wheat, and common vetch were conducted with the 12 common cotton and peanut herbicides at the Wiregrass Research Extension Center in Headland, Alabama and E.V. Smith Research and Extension Center in Tallassee, Alabama, from October 2016 to April 2017.
