Pasture Weed Control Database
Glyphosate may be applied between cuttings to control crabgrass in established bermudagrass hayfields. Apply 8 to 10 fl oz/A of 4 lb/gal glyphosate as soon as the hay is removed after cutting. Be warned that glyphosate should not be used in this manner unless bermudagrass stunting, yield reduction and possible stand reduction can be tolerated. Applications made after regrowth is well under way will result in increased damage to the bermudagrass. We have tested this practice many times and the amount of bermudagrass injury is unpredictable. Injury ranged from almost none up to 50% stunting.
