Response of alfalfa (Medicago sativa) grown for seed production to glyphosate and SC-0224

Glyphosate and SC-0224, at rates that control dodder (75 to 150 g ae ha-1), injured flowers, caused flowers to abscise, and sometimes reduced seed yields when applied to alfalfa when buds or blooms were present. Glyphosate at 75 or 150 g ha-1did not injure flowers, impair seed set, or reduce yield o...

Description
Summary:Glyphosate and SC-0224, at rates that control dodder (75 to 150 g ae ha-1), injured flowers, caused flowers to abscise, and sometimes reduced seed yields when applied to alfalfa when buds or blooms were present. Glyphosate at 75 or 150 g ha-1did not injure flowers, impair seed set, or reduce yield or quality of seed when applied to alfalfa foliage before the bud stage.
