Other claims from this paper (9)
- Observation Conyza was commonly found throughout the Central Valley.
- Observation Glyphosate-resistant individuals were confirmed in every field collection of both Conyza species.
- Association Field collections had 5- to 21-fold glyphosate resistance relative to susceptible plants, except one region.
- Observation One region had glyphosate resistance similar to susceptible plants.
- Observation Self-pollinated hairy fleabane accessions had 1.7- to 42.5-fold glyphosate resistance.
- Observation Self-pollinated horseweed accessions had 5.9- to 40.3-fold glyphosate resistance.
- Observation Three hairy fleabane accessions from different genetic groups were paraquat resistant at 40.1- to 352.5-fold.
- Observation One glyphosate-resistant horseweed accession was also paraquat resistant at 322.8-fold, the first confirmed California case.
- Observation The authors infer that multiple resistant Conyza developed independently several times in California.
