When should the Roundup® herbicide be applied to Genuity® Roundup Ready® alfalfa?
Unsurpassed weed control and crop safety starts with flexible application timing. For production management, ask for the America’s Alfalfa Genuity® Roundup Ready® Alfalfa Management Guide booklet. Always start with a weed-free field. In no-till and reduced-till systems, apply a herbicide burndown application to control existing weeds at least 1 to 2 weeks before planting. In both newly seeded and established stands, to preserve the yield and quality potential of forage and hay, applications should be made after weeds have emerged, but before alfalfa growth or re-growth interferes with application spray coverage of the target weeds. Research data indicate for the most effective stand establishment, a single application of a Roundup® herbicide at the seedling stage should be applied when your alfalfa is in the 3 to 4 trifoliate stage.
Due to the genetic diversity of alfalfa, a small percentage of the seedlings are susceptible and will not survive the first application of Roundup®. An application in the 6 to 9 trifoliate stage will setup your crop for superior quality harvest. Refer to your crop protection dealer for latest recommendation for Roundup® herbicide.
Does the Genuity® Roundup Ready® Alfalfa require additional seeding rate?
No increase in seeding rate is required. An early glyphosate application is recommended to control weeds during this critical phase of stand establishment, and to eliminate the small percentage of null seedlings found in any Genuity® Roundup Ready® alfalfa variety. No stand loss is associated with any subsequent glyphosate application. In fact, application of glyphosate when required for weed control after stand establishment shows benefits in improved alfalfa stand and plant health by controlling weed competition.
