In your 2 gal tank0.37 oz wt0.18 oz wt per gallon · covers 1,000 sq ft

Tanks to mix5.010 gal of water in total
0.37 oz wt per 1,000 sq ft. A dry powder weighed in fractions of an ounce; the annual cap differs between registrations, so check the jug you own. Kills crabgrass that a pre-emergent missed, which almost nothing else does.
Label wants 0.5–1 gal of water per 1,000 sq ft — that puts a 2 gal tank at 2,000–4,000 sq ft.
- Measured by weight, not volume — this is a dry powder, so it wants a gram scale rather than a measuring cup.
- Methylated seed oil at 0.55 fl oz per 1,000 sq ft — it barely works without it.
- No water for 24 hours, then at least ½ inch two to seven days later.
- 0.367 oz by weight per 1,000 sq ft a year on this registration.
- Not for St. Augustine, centipede, bahia, carpetgrass or dichondra, and not fine fescue unless it is part of a blend.
- Read the label — it governs, not this page.
