Compare-N-Save 75324 Herbicide, 1-gallon, white
✅ PROS
- Active ingredient is the same 41% glyphosate concentrate sold by bigger brands, at roughly half the cost per ounce
- 1-gallon jug mixes to 43 gallons of ready-to-spray solution — handles large properties or multiple seasons
- Works on over 200 weed types including poison ivy, crabgrass, and dandelions; visible results in 24-48 hours
❌ CONS
- It's non-selective — kills EVERYTHING it touches, including desirable grass and flowers if you're careless
- White plastic jug is thin and the cap can drip; you'll want to transfer to a sprayer with a sealed lid
The Verdict
If you’ve priced name-brand glyphosate concentrates lately, you know the pain. A quart of the blue-jug stuff runs $20-plus. Compare-N-Save 75324 gives you a full gallon of the same 41% active ingredient (isopropylamine salt of glyphosate) for roughly the same money. That’s the headline. But let’s dig into whether the savings cost you anything else.
What’s in the jug
You get one gallon of milky-white concentrate. The label says it mixes at 2.5 to 5 ounces per gallon of water depending on weed toughness — so figure 25 to 50 gallons of ready-to-spray solution per jug. For context, that covers a LOT of fence lines, driveway cracks, and patio edges. A 1-gallon pump sprayer filled with the standard mix will knock out a typical suburban yard’s worth of weeds several times over.
Real-world performance
The active chemistry here matches the industry standard. Spray it on a sunny day above 60°F, and you’ll see weeds yellowing within 24 hours, fully crisped in 7-10 days. It’s systemic, so it kills roots — not just leaves. That matters for perennial monsters like bindweed and poison ivy, where surface-only sprays just make them angry.
One caveat: rain. Check the forecast. If it pours within six hours of application, you’re redoing that section. That’s true of every glyphosate product, but worth stating plainly.
What buyers consistently say
The 4.5-star rating across 225 reviews holds up. The dominant theme in customer feedback is value. One reviewer put it simply: “Same active ingredient as the big names, half the price. Why pay more?” Another noted the jug lasted them two full seasons for a half-acre property — a detail that tracks with the dilution math.
Gardeners also repeatedly praise it for spot treatment before planting. Spray, wait ten days, till — no regrowth. That’s the systemic action doing its job.
Where it falls short
This is not a selective herbicide. It doesn’t know a dandelion from a daylily. Drift from a windy day, a sloppy spray pattern, or overspray onto lawn edges will leave brown streaks that take weeks to recover. Use a dedicated sprayer with a fan nozzle on a calm day, and you’re fine — but treat it with respect.
The jug itself is functional, not fancy. The white plastic is thin, and the cap doesn’t seal perfectly after the foil seal is removed. Store it upright, or you’ll find a puddle of concentrate in your garage. Transferring to a labeled sprayer bottle is the smarter move anyway.
Who should buy this
If you maintain a fence line, gravel driveway, patio, or garden paths — and you’re tired of paying premium prices for a chemical that’s chemically identical — this is your jug. It’s also a strong choice for property owners with invasive weeds (kudzu, Japanese knotweed, poison ivy) who need volume, not fancy additives.
Skip it if you’re looking to selectively kill broadleaf weeds in your lawn. For that, you want a 2,4-D or dicamba-based product that leaves grass unharmed. This isn’t that tool.
FAQ
Q: How much does this make when mixed? A: At the standard 2.5-ounce rate, one gallon makes 51 gallons of spray. At the heavy 5-ounce rate for tough perennials, about 25 gallons. Both figures are on the label.
Q: Is it safe around pets and kids? A: Once dried, glyphosate binds to soil and is essentially inert. Keep animals off the sprayed area until the solution dries (typically 1-2 hours). It’s a contact herbicide, not a soil sterilant.
Q: Can I use this in a spray bottle for small jobs? A: Yes, but mix it fresh and use it within a day or two. The concentrate is stable, but diluted solution loses potency over time. For tiny jobs, mix only what you need.
The Verdict
Buy it if: You want the same glyphosate chemistry as name brands at a fraction of the cost, and you have the sprayer and common sense to apply it carefully. This is a 4.6/5 product for anyone with a weed problem bigger than a window box.
Skip it if: You need a selective lawn-safe formula, or you’re not comfortable handling concentrated chemicals. In that case, buy a ready-to-use spray bottle and pay the convenience tax.
For everyone else: this is the value pick that actually delivers. The savings are real, the results are proven, and the only “catch” is that it does exactly what it says — kills everything green it touches.
