6.3 fl oz per 1,000 sq ft (label range 6.3–6.4). The label sells it as 2.5 fl oz per gallon covering 400 sq ft, which works out to 6.25 fl oz per 1,000 sq ft — just under its own 6.4 ceiling. The big-box answer when you have both weeds and crabgrass.
Label wants 2.5 gal of water per 1,000 sq ft — that puts a 2 gal tank at 800 sq ft.
- Spot spraying: 2.5 fl oz per gallon on the label — for touch-ups, not for covering the lawn.
- Water the day before, then leave it dry for 24 hours after.
- Rainproof in an hour; back on the lawn once dry.
- 2 applications a year, 21 days apart; 12.8 fl oz per 1,000 sq ft a season.
- Not for St. Augustine (including Floratam), bahia, bentgrass, carpetgrass, centipede or seashore paspalum. Bermuda only below 85°F.
- Read the label — it governs, not this page.
