Other claims from this paper (18)
- Intervention effect Glyphosate gave consistent weed control in wide and narrow rows in both years.
- Intervention effect Adding flumiclorac to glyphosate reduced common ragweed control in wide rows.
- Intervention effect Adding flumiclorac to glyphosate reduced velvetleaf control in wide rows.
- Intervention effect Weed control without glyphosate was generally greater in narrow rows than wide rows.
- Intervention effect Most herbicide treatments in narrow rows gave yields equal to the weed-free control.
- Intervention effect Narrow-row soybean had greater gross margins than wide-row soybean.
- Observation Glyphosate had the greatest gross margins in both years.
- Observation Glyphosate plus AMS had the greatest gross margins in both years.
- Intervention effect Adding AMS, flumiclorac, or imazethapyr did not improve weed control or yield.
- Observation Reduced-rate fomesafen mixture controlled broadleaf weeds.
- Observation The reduced-rate fomesafen mixture gave acceptable giant foxtail control in one of two years.
- Intervention effect Sequential reduced-rate quizalofop mixture improved common ragweed control against one full-rate application in 1996.
- Intervention effect Reduced application rates yielded similarly to weed-free controls only in narrow rows.
- Intervention effect Preemergence followed by postemergence programs gave more consistent weed control than non-glyphosate total postemergence programs.
- Intervention effect Those sequential programs yielded similarly to weed-free controls in narrow rows only.
- Intervention effect In 1996 narrow rows exceeded wide rows in gross margin by $26 per acre.
- Intervention effect In 1997 narrow rows exceeded wide rows in gross margin by $18 per acre.
- Recommendation The authors recommend considering costs, application timing, and risk when selecting weed management programs.
