Abstract excerpt

BACKGROUND: Amaranthus is a highly troublesome weed genera globally. Most cotton, corn, and soybean fields in the US mid-south have Amaranthus palmeri populations resistant to protoporphyrinogen oxidase (PPO)-inhibiting herbicides. We evaluated the persistence of resistance to PPO-inhibiting herbicides in A. palmeri populations from Greene (GRE-A) and Crittenden (CRI-D) counties, Arkansas, collected in 2015 and...
