Clifford H. Koger; Daniel H. Poston; Robert M. Hayes; et al. Weed Technology 2004. doi:10.1614/wt-03-218r
Other claims from this paper (7)
- Observation Horseweed survived recommended glyphosate rates in cotton and soybean fields.
- Observation All horseweed biotypes had 8- to 12-fold glyphosate resistance versus a susceptible biotype.
- Observation One Mississippi resistant biotype was two- to fourfold more resistant than other resistant biotypes.
- Association Growth stage had little effect on the level of glyphosate resistance.
- Association Glyphosate GR50 for resistant horseweed rose from 0.14 to 2.2 kg/ha as plants grew.
- Observation Glyphosate GR50 for the susceptible horseweed biotype rose from 0.02 to 0.2 kg/ha.
- Observation Resistant horseweed biotypes survived glyphosate at up to 6.72 kg/ha.
