The Top 5 Commercial Weed Killers Reviewed
The most impressive thing about weeds is also the most frustrating: they find a way to grow out of just about any crack, hole and gap you don’t want them to. It could be a crack in the pavement outside your house, the gaps in your brand new patio or even the crevices in your driveway. They’re tenacious, positively thriving in what should be the most uninhabitable place of a blistering hot patch of tarmac or concrete.
But the fact they’re able to sprout up and grow in places where you’d think absolutely nothing could survive – nevermind positively thrive – is what makes them such a common annoyance, and so very hard to keep at bay.
And here’s the worst part: no amount of pulling, yanking or pouring boiling water over them will ever win you this war. Weeds are too hardcore and stubborn for that. They’ll simply bounce back with a smile that will leave you even more frustrated. Thankfully, this is a war you can win, you just need to up the ante and break out the commercial weed killer.
Of course, any and all chemical products need to be used carefully or else you could kill off more than just your weeds, but any weed killer made with glyphosate shouldn’t linger in the environment in the same way a lot of other chemical weed killers do. This means your grass, shrubs and other areas of friendly greenery should be left unharmed while your driveways, parking lots, backyards, gravel walkways and everything else will be left weed free.
So without further ado, here are five of the best commercial weed killers to test out on your problem areas:
Best Commercial Weed Killers
1. Compare-N-Save Concentrate Grass and Weed Killer
Pros: Rainproof in 2 hours, results in 3 days, covers a large area
Cons: Don’t apply to your lawn as it will harm grass
Rating: 4.3 out of 5 (9,400+ reviews)
For anyone that’s in the market for a great weed killer that’s ready and able to treat a large area, products don’t come any better than the Compare-N-Save Concentrate Grass and Weed Killer, which can easily cover over 25,000 square feet per container — a claim backed up by their impressive collection of reviews.
But that’s not the most impressive selling point because just a 1-gallon container is able to create more than 85 gallons of ready-to-use weed killing spray, which you can then apply to almost any weed-filled area you like, from driveways to garden walkways, fences, flower beds and even vegetable gardens. And because the Compare-N-Save Concentrate Grass and Weed Killer contains 41 percent glyphosate, you’ll find impressive results are visible in around three to five days.
What’s more, this weed killer becomes rain-resistant just 2 hours after you apply it, quickly working its way down to the root of your weeds to make it so effective that some reviewers claim it has kept weeds away for years.
Top comment: “This weed killer does exactly what I want it to do- it kills weeds dead in their tracks. I’ve got a huge problem with weeds where I live because the fields around my house are infested with them, and when the wind blows those seeds go right into my yard. Rats! I’ve tried so many things to get rid of weeds, but this weed killer is so powerful that I can spray a couple times (just to be safe) and all the weeds will die within 5 days.”
2. RM43 Total Vegetation Control
Pros: Prevents weeds for upto a year, kills everything, affordable
Cons: Mostly positive reviews but a common thread suggests ineffective on some weeds
Rating: 4.5 out of 5 (3,400+ reviews)
One thing every weed has in common is their ability to keep coming back. They’re resilient in that sense — and for a lot of people, they spot-spray their weeds only for them to return a week or so after being treated. When that’s the problem you’re faced with, you need a weed killer that’s celebrated for killing weeds and keeping them killed, which is exactly what the RM43 43-Percent Glyphosate Plus Weed Preventer is known for.
It’s also worth noting that, while RM43 doesn’t stretch as far as the Compare-N-Save product, a 1-gallon container makes up 21-gallons of spray meaning it is able to tackle a 17,000 square feet area, making it perfect for fences, pavements, concrete buildings, parking lots, farms, driveways and even gravel.
For something that is designed to kill off everything, it’s also incredibly adaptable. Use it as either a total vegetation control spray or spot treat your problem areas, whether that’s brush, vines or weeds. Just be careful not to spray it on any plants you’d quite like to keep because this killer takes no prisoners.
Top comment: “My hands are crippled from 25 years of weeding and this has saved me. It is NOT organic but I had to resort to it to save my beautiful flowers from being choked out from nasty invasives and horrible weed-take over.”
3. Ortho GroundClear Year Long Vegetation Killer
Pros: Prevents regrowth after 1 application, fast-acting formula, effective in 1-hour
Cons: Only kills “to the root” not the actual root
Rating: 4.4 out of 5 (700+ reviews)
The Ortho collection of weed treatments have quickly established a reputation for being both effective and affordable and their GroundClear solution is no different. Perfect for spot-treating your driveways, walkways, sidewalks, patio and gravel areas, especially for anyone living in mixed-weather climates because this product dries incredibly quickly and immediately gets to work killing weeds and grass to the root. And best of all, you can apply it when the weed is still actively growing and expect to see impressive results straight away.
In fact, their entire selling point is based around being able to kill weeds within one hour and prevent them from regrowing for up to one year, a claim that is backed up by the reviews with many stating they saw a noticeable difference overnight.
Top comment: “Every year I buy one can and that much is enough. The chemical is so strong that it is recommended to wear gloves while spraying this liquid. It kills the weeds and keeps them off for almost a year. The chemical is so strong that if it touches any grass patch, that patch gets killed automatically. Excellent product to keep the weeds off.”
4. RM18 Fast-Acting Weed & Grass Killer
Pros: Visible results in 12 hours, makes 42-gallons of ready-to-use spray, rain-proof in 30-mins
Cons: Only treats up to 12,600 square feet (which isn’t much compared to the others)
Rating: 4.0 out of 5 (400+ reviews)
This fast-acting product can only be described as a great multi-purpose weed killer that will do wonders around your home and/or place of work. Think driveways, sidewalks, patios, flower beds, vegetable patches, mulch and just about every other landscaped area in between. Translation: it’s one of the most versatile solutions no matter what weeds your facing, and that’s because it’s a combination of two herbicides.
But the best part is just how quickly it gets to work, killing your weeds the moment it makes contact with them so that you can see the difference in just 12 hours, while being rain-resistant in around half-an-hour. What’s more, this product has been proved to work on over 100 types of plants and weeds, such as kudzu, wild blackberry, poison ivy, poison oak, crabgrass and dandelions.
Top comment: “I used it the same as I did Spectricide. Exact same results, at half the price when you buy a gallon. It rained within the hour after I applied it. 24 Hours later, dying in the dirt. I will be buying this in the future, it’s on my essentials list.”
5. Roundup Pro Concentrate
Pros: Can be used in a diverse range of settings, contains a surfactant to increase effectiveness
Cons: Visible effects can take up 7 days
Rating: 4.7 out of 5 (500+ reviews)
Make no mistake about it: no other herbicide controls more weeds than Roundup Pro Concentrate, which has built up an incredible reputation across the board no matter what weeds you’re facing or the situation they’ve arisen. This product knows exactly how to keep your property free of weeds and it’s proven it time and time again with tens of thousands of people relying on this weed killer over the years.
Whether you’re looking to deal with broad-leaf weeds, annual and perennial Grasses, woody brush and trees or anything in between, this systemic herbicide gives you broad-spectrum control over a large variety of weeds. And because no residual chemical is left behind, this weed solution is a lot safer to use around residential and commercial properties than a lot of other alternatives on the market. Quite simply put, Roundup Pro Concentrate is the product everyone eventually turns to.
Top comment: “I love this stuff. I used to buy the premix or even the concentrate at Home Depot and they are sure more expensive. You have to be patient with this stuff because it may not seem like it works in the first there four days, but it sure kills the grass and weeds that I sprayed on.”
