Resistance to protoporphyrinogen oxidase inhibitors in giant ragweed (Ambrosia trifida)

Pest Management Science, Volume 80, Issue 12, Page 6211-6221, December 2024.
A codon change in PPX2 conferring a R98L substitution was identified as the most likely mechanism conferring protoporphyrinogen oxidase (PPO)‐inhibitor resistance in Ambrosia trifida. Abstract BACKGROUND Giant ragweed (Ambrosia trifida L.) is one of the most troublesome weed species in corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] cropping ...
