Protoporphyrinogen Oxidase (PPO) Inhibitor–resistant Waterhemp (Amaranthus tuberculatus) from Nebraska is Multiple Herbicide Resistant: Confirmation, Mechanism of Resistance, and Management
On the Cover: Four-way resistance (PPO, ALS, PS II, and EPSPS inhibitors) was confirmed in a waterhemp biotype collected from a soybean production field in eastern Nebraska (insets on left showing dose-response to different herbicides); the DG210 mutation conferring PPO-inhibitor resistance was confirmed using a Kompetitive Allele Specific PCR (KASP) assay.
