Our #1 Recommendation: Best Overall
Compare and Save weed killer is one of the most popular you’ll find, and for very good reason. It’s affordable, incredibly efficient, and you get a lot of it with one order. Add it all up, and you have our pick for the best conventional weed killer on the market.
This product is non-selective, so you will need to target it directly on the growths you want removed, as it will kill whatever it touches. Glyphosate is the main active ingredient, which accounts for 41% of the concentrate.
This particular size is one gallon, which can be mixed to cover up to 300 square feet.
Depending on your weed amount, it could very well treat even more space. Seeds are safe to plant 24 hours after treating the area.
Mixing is fairly standard. Take 1.5 ounces of concentrate and mix it with 1 gallon of water for general weed control. Tougher weed control of perennials or brush will require a mix of 2.5 ounces in 1 gallon of water.
It’s worth mentioning that this product is very potent, and can take it whatever you spray it on, so it has an astounding amount of versatility. You can definitely kill any vegetation you don’t want around, which of course includes grass making it one of the best permanent vegetation killers.
Compare-N-Save’s Concentrate Grass and WeedKiller is as economical as it is effective. If you’re okay to use non-selective herbicides, and you want an affordable product that can treat a large area, this is the one of the best herbicides to buy.
Our #2 Recommendation : Best Budget
Roundup is a well-known name in the herbicide industry, and products like this are a good reason why. Weed and Grass Killer Concentrate Plus is made to quickly kill a wide range of weeds and unwanted growths.
Weed and Grass Killer Concentrate Plus relies on glyphosate as its main ingredient, but also uses a bit of diquat dibromide as well. This gives the product enough potency to quickly kill weeds and grass along driveway, fences, within mulch gardens, and really just about everywhere else.
Do note that this a concentrate, and does not come with a sprayer. To mix for conventional use, it takes 6 ounces of concentrate to one gallon of water. This is a half gallon of concentrate, so you’re getting about 10-11 gallons of usable weed killer with each purchase.
Due to its potency and non-selective chemical makeup, Weed and Grass Killer Concentrate Plus should not be used around any edible growths. The product works in about 12 hours, and is totally rainproof after 30 minutes.
If you’re looking for a fast-acting weed killer that works on most any growth, Roundup Weed and Grass Killer Concentrate Plus is a suitable choice that offers a good amount of value and versatility and is one of the best grass killers.
More Great Buys

Weed and Grass Killer III combines the ever-popular glyphosate with another strong active ingredient; pelargonic acid. This gives the product a very efficient one-two punch that will take out basically anything it comes in contact with, right down to the root.

We already appreciate weed killers that come with their own sprayers, but it certainly helps things when the product itself is highly effective. Because of this, we strongly recommend Weed and Roundup Grass Killer III as one of the best weed killer spray.

Roundup’s Extended Weed Control and Grass Killer Plus Weed Preventer II does exactly that, combining a potent weed and grass killer with preventative measures that will keep the area clearer for longer.
Like most others, Extended Weed Control and Grass Killer Plus Weed Preventer II uses glyphosate as its main active ingredient, but also contains a small amount of imazapic, which helps prevent new weeds from growing for months after use.
This particular size is 16 ounces, which is less than the half and one-gallon sizes that make up most of this list, but that’s by design.
Since this is a weed preventer as well, you won’t need to be using as much as you would with a normal one, as the preventer ensures less applications.
6 ounces of Extended Weed Control and Grass Killer Plus Weed Preventer II can be mixed with one gallon of water or standard use. A pump sprayer is best, and this product can then be applied to numerous areas, including gravel, mulch, tree rings, fence lines, and much more.

Ortho Groundclear does exactly was the name describes. Weeds, grass, plants — all of these are no match for its potent chemical blend. And better yet, it keeps these weeds and other vegetation away for a very, very long time making it one of the best vegetation killers available in market.
Groundclear uses glyphosate as its base, and adds in imazapyr as a secondary ingredient to prevent new growth. You still get fast-acting results you’ll see in just a few hours, while also withstanding rain after 30 minutes of settling.
This is a concentrate in every way.
You have the option to use whichever ratio you’d like, but even a few ounces in a gallon of water will give you enough potency to effectively treat a large area. This is two gallons, so it’s definitely going to last you awhile.
After application, you’ll see weeds, grass, and other plants that have been sprayed start withering away after a few hours. The effect will last up to one full year after you spray it, which is far longer than most other weed killer + preventers on the market. This makes Groundclear very good for larger yards.
Don’t be deceived by the higher price. With Ortho’s Groundclear, you’re not only getting two full gallons of concentrate, you’re getting a product that will annihilate anything it touches, and keep it from coming back for nearly a year.
Bayer’s Advanced Durazone Concentrate is dual-action weed killer that can quickly eliminate weeds and other bothersome vegetation in a matter of hours, while also preventing new growth for up to 6 full months.
Durazone WeedKiller uses glyphosate as its main ingredient, and backs it up with a combination of diquat dibromide and indaziflam, giving it a three-way attack that easily kills all the way down to the root.
This economical 32 ounce size can be used to make 4 full gallons of usable herbicide, which is best applied when using a pump sprayer.
You can get about 1,500 square feet of use out of just one bottle, making it great for larger landscapes and yards.
Any area where you apply Durazone Concentrate will stay clear for 6 months, so you can quickly kill weeds and control them using the same product, while cutting down on the number of times you’ll need to use it. This product is most effective on driveways, sidewalks, mulched areas, and along fences as well.
Bayer Advanced Durazone is among the best you can use for weed killers that also prevent new growths for an extended amount of time. The low price and expanded area range makes it one of the best weed control concentrates for anyone needing to be rid of and control weeds.
Fertilome is a lesser-known manufacturer, which is a shame since they make one of the most effective and affordable weed killers you can find. Killzall Weed and Grass Killer lives up to its name, as it wipes out whatever you spray it on.
Killzall Weed and Grass Killer uses a large amount of glyphosate as its main ingredient and nothing else, relying on the power of this widely-used vegetation killer.
You get 32 ounces with this purchase, and although it’s not as much as some other products, the ratio for mixing is quite lower.
You can use just 5 tablespoons of Killzall Weed and Grass Killer to treat a gallon of water, and that’s enough to kill even the toughest of weeds.
Killzall Weed and Grass Killer can be used anywhere that you have unwanted weeds and grass, but be aware that it will kill any vegetation it ends up on, so don’t use it around fruit and veggie gardens. It is rainproof after sitting for two full hours.
Fertilome Killzall Weed and Grass Killer may not be flashy, but it gets the job done, and it’s available for an extremely low price under $10. If you want to kill as many weeds as possible while spending the least amount of money, this is the way to do it.
Spectracide Weed and Grass Killer 2 is one of the most economical weed killers on this list, and it performs on the same level as similar products that cost twice as much. As a general weed and grass killer this is hard to beat, especially when considering the price.
Weed and Grass Killer 2 forgoes the usual glyphosate for a mix of active ingredients that is anchored by diquat dibromide, and supported with an array of other effective killers. This combination results in one of the most fact-acting products you’ll encounter.
Weed and Grass Killer 2 comes in a one gallon size, and includes its own sprayer, so you can use it as soon as it arrives. While not a concentrate, it does not require much of a spray to be effective. The product has no soil activity, so it won’t affect nearby untreated plants.
You can use this killer anywhere you’d use similar products, which includes walkways, mulch, tree rings, fence lines, and of course cement cracks in a sidewalk, patio, or driveway. You’ll see results in about 3 hours, and the product is rainproof after sitting for 15 minutes.
Spectracide Weed and Grass Killer 2 is best for those who haven’t had a lot of good results with glyphosate, and need to kill weeds such as dandelions, plantains, and blue grass, while saving as much money as possible. Considering the price it is one of the best commercial weed killers in the market.
For those that take an organic approach to their gardening, or simply want to avoid the use of chemicals, Bonide’s Burnout Natural is an excellent choice. Intended mostly for grassy and broadleaf weeds, this product is surprisingly effective when used properly.
The active ingredients in Bonide Burnout are citric acid and clove oil, which not only avoids spraying chemicals on your yard, they actually pleasant to smell as well. Yes, you’ll need to spray more onto the weed than you would with chemical products, but it works, and it works well.
This size of Bonide’s Burnout is one gallon, and it is not a concentrate. Still, when considering the price, it’s a great value, especially since it comes with an integrated sprayer, saving you from having to buy a seperate one and/or also mixing with water.
Although this product is made to kill weeds, it can also be used to remove stubborn grass growth in cement cracks, and as a spot treatment within your garden for wayward weeds and unwanted grass growth.
Natural weed killers sometimes get a bad rap, mainly because they aren’t as potent as chemical weed killers. That’s not the case with Bonide’s Burnout Natural, as it’s effective when used correctly, and safe to use around people, pets, and other things you may be growing. Definitely a great product.
Whether you like to avoid using outright weed killers, or simply want a way to maintain an already weed-free area, Preen’s Garden Weed Preventer is a superior choice. This is for sections where you’ve already removed existing weeds, and need an easy way to keep it that way.

The weed killer has been pre-mixed, so there’s no need to worry about doing it yourself.
This particular version comes with a crabgrass wand, making application even easier and more seamless.
40 ounces is a lot less than you get with a concentrate, but if you are using this on a standard sized lawn, it’s enough to go around. A one gallon version is available for those with larger yards or property needs.
The combination of crabgrass and weeds are common threats to many yards. Ortho Weed-B-Gon Plus Crabgrass Control offers an all-in-one solution for a fair price, which is why I recommend it.

What is the Best Weed Control that You Should Buy ?
Breaking down the different types and uses of weed killers is quite simple when you base it off of what they are capable of.
This is the most basic form of these products. If the weed killer is simply marketed as a weedkiller and nothing more, it’s safe to assume that it will kill weeds and other vegetation on contact, but it’s up to you on how to prevent new growth in the future — or just apply again as needed.
Great For: Killing weeds and grass in small areas, such as sidewalks, driveways, walking paths, and spot treatment in smaller mulched areas and tree rings.
Weed Killer + Controllers will not only kill the weeds, but prevent new ones from forming on that same spot. They usually have one ingredient for killing the weed, and another that penetrates the soil and prevents anything else from growing.
Great For: High volume weed areas away from desirable vegetation, tree rings, larger sidewalks and driveways.
Weed preventative products aren’t technically weed killers in the fullest sense, but they are still closely related. These are often granular spreads that you can use like fertilizer, but only work where there aren’t any weeds.
Weed preventatives are most effective when they follow up weed killers after a few weeks, or after you’ve removed weeds in the treated area by hand.
Great For: Gardens, planters, mulched flower beds.
Not everyone likes to use chemicals on their property, be it for ecological reasons, or protect wildlife and edible vegetation these are one of the best weed killers that you can buy.
Natural and/or organic killers often use concentrated oils derived from any number of organic compounds, including citrus, mint, and clove. These can be just as effective as conventional weed killers when used on the right weeds and vegetation. You can make your own weed killer by simply following the steps given in this post by Naturallivingideas.com
Great For: The environmentally conscious, food and herb gardens, those with visiting wildlife, pets, and small children.
Before You Buy
The most important thing you need to determine before actually purchasing a weed killer is the type of weed(s) you are dealing with. Identifying the type of weed will allow you to choose the right product that specifically targets that weed, leading to more effective results, while also protecting your other plants and grass.
Do you know what type of weed is it? If not, take a close look at this handy weed identification guide for help.
Do you want to kill the weeds only, or everything including your grass?
Certain types of weed killers react differently to other types of vegetation. You can take the all-out approach of using a weed killer that kills everything it touches, or use more selective
products that either target just weeds, or weeds and other brush-like vegetation.
This is the core difference between selective and non-selective weed killers.
The advantages a car air freshener provides should be fairly obvious. Depending on which one you get, you can restore that long gone new car smell, mask unpleasant smells, or simply add your own personal scent choice to the interior, helping improve the feel and environment when inside.
Triclopyr is a popular herbicide that kills both weeds and brush, but it can be more expensive for the most part.
On the other hand, 2, 4 D weed killers are popular due to their more specific targeting of weeds that leaves grass unaffected. The compound in 2, 4 D products causes weeds to grow at an abnormal rate for a week or two, causing them to die off.
2, 4 D makes it easy to apply throughout a yard, without worrying about accidentally killing your grass. This makes it ideal for yards with spotty weed occurrences randomly throughout.
