8.3 fl oz per 1,000 sq ft (label range 5.0–8.3). The label sells it by mix: 1.5 fl oz per gallon for annual weeds, 2.5 for perennials and lawn renovation, a gallon of spray per 300 sq ft. Check the percentage on your jug — "Roundup Concentrate Plus" is 18% with diquat, not 41%, and mixes differently.
Label wants 3.3 gal of water per 1,000 sq ft — that puts a 2 gal tank at 606 sq ft.
- Spot spraying: 2.5 fl oz per gallon on the label — for touch-ups, not for covering the lawn.
- Do not water in — leave it on the leaf.
- Non-selective — it kills the lawn along with the weeds. Spot or renovation only.
- Read the label — it governs, not this page.
