• Evolution of Resistance to Auxinic Herbicides: Historical Perspectives, Mechanisms of Resistance, and Implications for Broadleaf Weed Management in Agronomic Crops (2011, background): “Much like giant ragweed in corn and soybean production, Palmer amaranth is highly competitive with cotton and soybean, causing potential crop yield losses up to 100% (Culpepper et al. 2006).”
• Gene amplification confers glyphosate resistance in Amaranthus palmeri (2009, background): “1032 | www.pnas.org/cgi/doi/10.1073/pnas.0906649107 Gaines et al. Our data demonstrate that glyphosate resistance in aGeorgiaA. palmeri population is due tomany-fold amplification of theEPSPS gene on multiple chromosomes.”
• Residual Herbicides for Palmer Amaranth Control (2011, background): “Glyphosate-resistant Palmer amaranth was first suspected in Georgia in 2004 and confirmed in 2005 (Culpepper et al., 2006), and it was first noted in North Carolina in 2005 (York et al.”
