Bromoxynil-Resistant Common Groundsel (Senecio vulgaris)

  • Carol Mallory-Smith (a1)


Resistance to bromoxynil and terbacil was confirmed in common groundsel collected from peppermint (Mentha piperita) fields in Oregon. This is the first reported case of a bromoxynil-resistant weed selected under field conditions. The bromoxynil rate required to reduce growth by 50% was 10 times higher for the resistant biotype than for the susceptible biotype. The bromoxynil-resistant biotype also was resistant to terbacil.
