Roundup Quickpro 6.8lb 4 Bottles

The Verdict

The Bottom Line Up Front: If you’ve got a serious weed problem — think fence lines, gravel driveways, or that patch of poison ivy behind the shed — Roundup Quickpro is the professional-grade answer. This isn’t the watered-down stuff in a spray bottle at the grocery store. With a 4.7-star average across 235 ratings, it’s a proven performer, but it demands respect and a bit of setup work.

What You Actually Get

The box contains four 6.8-pound bottles of water-soluble concentrate. Each bottle mixes to 20 gallons of finished spray solution. The powder dissolves quickly in water — no clumping, no residue left in the tank. The included measuring cap is genuinely useful, marked clearly for the correct dilution rate.

How It Performs in the Real World

Here’s where Quickpro separates itself from the consumer-grade Roundup products. The active ingredient load is significantly higher, and it includes a built-in surfactant that helps the herbicide penetrate waxy leaf surfaces. In practice, this means you’ll see visible wilting and yellowing within 24 to 48 hours on most annual weeds. Tough perennials like bindweed, Canadian thistle, and woody brush take longer — expect a week or two for complete kill.

The marker dye is a small feature that pays big dividends. You can see exactly where you’ve sprayed, which prevents both over-application and missed spots. For a product this potent, that visibility matters.

One buyer noted: “I’ve used this for years on my farm. Nothing else touches the multiflora rose and poison ivy like Quickpro does. The dye lets my crew see coverage instantly.”

Another added: “Mixed a batch for my gravel driveway. Two weeks later, it looked like I’d pressure-washed the whole thing. No weeds, no regrowth for months.”

Where It Falls Short

Let’s be direct about the downsides. First, this is a concentrate — you need a pump sprayer or backpack sprayer. If you’re looking for a grab-and-go solution, this isn’t it. Second, it’s non-selective. Wind drift onto your prized hydrangeas or vegetable garden will kill them. Spray on calm days and use a shielded nozzle.

Third, patience is required. The visible top-kill happens fast, but the roots take longer to die. If you mow or pull treated weeds too soon, you’ll leave roots intact and get regrowth. Plan to leave treated areas alone for at least a week.

Who Should Buy This

This four-pack is aimed squarely at property owners with serious acreage or persistent weed problems. Think homesteaders, small farm operators, or anyone managing a large rural property. If you’re maintaining a standard suburban quarter-acre lot, this is overkill — you’d be buying a five-year supply. A single bottle would serve most homeowners for multiple seasons.

Renters or apartment dwellers should skip this entirely. You don’t need 80 gallons of herbicide capacity for a balcony.

Three Questions Shoppers Ask

Is this safe for pets and kids? Once the spray has dried, it’s generally considered safe. But keep pets and children off treated areas until the solution is completely dry — typically a few hours. The product is non-selective, so it has no built-in safety margin for plants, only for mammals when used as directed.

How long does it take to work? You’ll see visible damage within 24-48 hours on most weeds. Complete root kill on tough perennials takes 7-14 days. Rain within 30 minutes of application reduces effectiveness, so check the forecast.

Can I use this on my lawn to kill weeds without killing grass? No. This is non-selective. It kills everything. For lawn-safe weed control, you need a selective herbicide designed for turf. Don’t confuse the two.

The Verdict

Buy it if: You have significant weed problems on driveways, fence lines, or pasture areas, and you already own or are willing to buy a decent sprayer. The cost per gallon of finished spray is dramatically lower than ready-to-use products, and the effectiveness is noticeably better.

Skip it if: You only need to spot-treat a few dandelions in a small lawn, or you’re not comfortable mixing chemicals and managing spray drift.

Rating: 4.6/5 — Deducting a half-star for the learning curve and the potential for damage if you’re careless with drift. For anyone willing to follow the label, this is the most effective herbicide you can buy without a commercial applicator’s license.
