e0“Glyphosate applied once (two- to four-leaf canola) or twice (two- to four-leaf followed by five- to six-leaf canola) in-crop provided similar weed control, dockage, and canola yield as ethalfluralin applied PRE in the fall followed by an in-crop mixture of sethoxydim, ethametsulfuron, and clopyralid; and superior weed control and canola yield and lower dockage than ethalfluralin alone or an in-crop mixture of sethoxydim and ethametsulfuron.”

- Intervention effect Preseeding spring glyphosate improved weed control over fall 2,4-D.
- Intervention effect Preseeding spring glyphosate reduced dockage relative to fall 2,4-D.
- Intervention effect Preseeding spring glyphosate increased canola yield and net return relative to fall 2,4-D.
- Intervention effect In-crop glyphosate gave superior weed control and canola yield to the simpler traditional regimes.
- Intervention effect In-crop glyphosate reduced dockage versus the simpler traditional regimes.
- Intervention effect In-crop glyphosate produced higher net revenues than other treatments.
- Intervention effect A second in-crop glyphosate application offered little or no advantage over one.
- Intervention effect The glyphosate system used less herbicide active ingredient than most traditional regimes, especially with one application.
