- Observation At 3 weeks, glyphosate doses for 50%, 80% and 90% annual ryegrass control were 439, 1757 and >2700 g a.e. ha −1.
- Observation At 4 weeks, the corresponding doses were 526, 2105 and >2700 g a.e. ha −1.
- Observation At 6 weeks, the corresponding doses were 703, >2700 and >2700 g a.e. ha −1.
- Observation Glyphosate alone controlled annual ryegrass by 27% to 77% across 1 to 6 weeks.
- Observation Glyphosate plus clethodim controlled annual ryegrass as much as 82%.
- Observation Glyphosate plus fluazifop-P-butyl controlled annual ryegrass as much as 79%.
- Observation Glyphosate plus quizalofop-P-ethyl controlled annual ryegrass as much as 82%.
- Observation Glyphosate plus sethoxydim controlled annual ryegrass as much as 84%.
- Observation Glyphosate plus saflufenacil controlled annual ryegrass as much as 81%.
- Intervention effect Glyphosate plus Group 1 herbicides increased corn yield as much as 66%.
- Intervention effect Glyphosate plus saflufenacil increased corn yield 69% through reduced ryegrass interference.
