Confirmation and inheritance of glufosinate resistance in an Amaranthus palmeri population from North Carolina.

ABSTRACT: A putative glufosinate-resistant Amaranthus palmeri population was reported in 2015 in Anson County, North Carolina. The results from dose-response assays conducted in the field suggested plants were surviving lethal rates of glufosinate. Dose-response assays conducted in the glasshouse determined the Anson County accession exhibited reduced susceptibility to glufosinate compared to three glufosinate-susceptible populations. The LD₅₀ values (210-316 g ai ha^-1) for the Anson County population were always higher than the LD₅₀ values (118-158 g ai ha^-1) for the tested susceptible populations from the dose-response assays. Anson County plants that survived lethal glufosinate rates were reciprocally crossed with susceptible plants to create F
