Pigweeds are among the most difficult weeds to manage in row crop systems due to their rapid growth, high seed production and widespread herbicide resistance. During the past two decades, reliance on herbicides for weed management has led to the evolution of resistance in Palmer amaranth populations to several herbicides, particularly ALS -- acetolactate synthase -- glyphosate and PPO-inhibitors. That reality has intensified the need for integrated weed management strategies, including non-chemical practices such as cover crops.
