Johnsongrass is one of the problematic weeds in the Southern US, having evolved resistance to glyphosate, ALS inhibitors, and ACCase inhibitors. It can propagate through seeds and rhizomes, which facilitates its spread by various vectors and processes. Glyphosate-resistant johnsongrass has been confirmed in Louisiana. This study aims to understand...
