Weeds in Gravel and Driveways: Why They Keep Coming Back
Every ready-to-use bottle for hardscape is a contact killer. NC State: they knock down top growth only, and none have residual activity in soil.

The cheapest gallon on the shelf, and the ingredient list explains why it must stay off turf: one of the three actives exists specifically to kill grasses.
Our Verdict
Good value for what it is, which is a hardscape and bed-edge product. The three-way mix is deliberate: diquat burns everything it touches for the quick visible result, fluazifop is a graminicide that kills grasses, and a small amount of dicamba adds broadleaf activity. That combination is why it clears a driveway seam quickly and why spraying it on a lawn produces a dead patch rather than a weeded one. Also worth knowing since the label wording confuses people: Spectracide's weed and grass killers are not glyphosate products, so 'no glyphosate' is not a distinguishing feature here. At six dollars a gallon it is hard to argue with for paving, gravel and fence lines.
✅ Pros
- The lowest cost per gallon of any ready-to-use in this list
- Diquat gives a fast visible burn, so missed spots are obvious
- Contains no glyphosate
- Ready to use — no mixing
⚠️ Cons
- Fluazifop is a grass killer by design — this will kill lawn turf
- Contact burn on top growth; perennial roots survive and regrow
- Dicamba can move in soil and injure shrubs and trees if overapplied near root zones
- No residual, so treated cracks recolonise within weeks

Where our facts come from
Registration confirmed, label text not read
EPA Reg. No. 9688-293-8845
The registration exists and we confirmed it, but no label document was available to read. Treat the concentration and general use pattern as sound and take rates from the container itself.
What we found when we read it
Registration located 2026-08-03: the ready-to-use Spectracide Weed & Grass Killer is reported as EPA Reg. 9688-293-8845 — a distributor product (base 9688-293, distributor 8845). The CONCENTRATE is a separate registration, 9688-265-8845, which is a common way to get the wrong figures. Full label text not read, so the percentages in this record come from the manufacturer's SDS rather than from the label, and Spectracide's line contains several formulations with different actives under similar names.
Where this page and the container disagree, the container wins — the label is the legal authority on rates and restrictions. How to read one yourself.
