Full rate for gly is 1 qt per acre. Spraying low rates of any herbicide (especially gly) is bad advice and a horrible idea. That is exactly how herbicide tolerance develops. We already have some weeds in Alabama that are nearly impossible to control now - Palmer pigweed and marestail. They developed resistance to gly from people spraying at low rates. Alway, always, always spray full rate. If you want to control broadleafs in clover use 24DB when weeds are small. If you want to control grass spray Clethedom. Roundup is not labeled nor recommended for clover
