Abstract Glufosinate is among the few remaining effective herbicides for postemergence weed control in North Carolina crops. The evolution of glufosinate resistance key weeds currently not widespread Carolina, but to better assess current status effectiveness, surveys were distributed at Extension meetings 2019 and 2020. designed provide information about farmers’ perception its use. Survey results indicate that many farmers (≥26%) apply correct timing (5- 10-cm weeds). In addition, (≥22%) are applying as a complementary herbicide other efficacious herbicide-resistant weeds, suggesting part diverse chemical management plan. Conversely, survey findings indicated some (13% 17%) rely exclusively on control. Additionally, 28% 30% reported failures, failures observed several species corn, cotton, soybean suggest most stewarding glufosinate, they also support need personnel keep educating how correctly use delay glufosinate-resistant weeds. Semiannual should be monitor where occur being controlled.
