Distribution of target-site resistance mechanisms to nicosulfuron and glyphosate in Amaranthus palmeri accessions from two different regions of Türkiye

Palmer amaranth (Amaranthus palmeri S. Watson) is a highly competitive weed that has evolved resistance to several modes of action and has recently become a significant problem in Türkiye. This study was designed to determine the distribution of common target-site resistance (TSR) mechanisms to the acetolactate synthas...

Characterization of a novel R98Q mutation that confers resistance to sulfentrazone in common ragweed (Ambrosia artemisiifolia) populations from Michigan

BACKGROUND In 2023, soybean growers in Eaton County, Michigan, reported repeated failures to control common ragweed (Ambrosia artemisiifolia L.) with (PPO)-inhibiting herbicides, sulfentrazone and fomesafen, in non-genetically modified soybeans. This study aimed to investigate resistance levels and mechanisms of resist...
