You don’t have to be an expert landscaper to know that there are absolutely no reasons to ever have weeds on your property. Weeds are ugly, invasive, and sometimes even dangerous to an extent. If you have weeds, you want them gone. Period. We can all agree on that.
So how do you get rid of weeds? Unless you want to spend all your time pulling them all out by hand, weed killers are the only logical solution.
Anyone that has a property with vegetation knows the struggles and problems weeds can cause, whether you have a front and backyard, a garden, or are trying to keep your landscaping at its best for a commercial property. That’s where weed killers come in.
But here’s the thing though: not all weed killers are created equally. Some work in different ways, while others hardly work at all. Walk into a hardware store, and you’ll be overwhelmed with plenty of products claiming to kill weeds, but do they actually work?
As a licensed turf applicator, I can say yes and no. It depends on what you buy, and what your needs are.
For those who are looking for the best weed killer for their needs but have no idea to start, you’re in luck. I’ve analyzed a wide range of different weed killers, selecting 15 products that I can fully recommend.
Are you a novice when it comes to yard care? No worries, I’ll explain how it all works, how to determine which type to buy, and of course plenty of recommendations for a wide variety of uses, whether you have a small yard, big yard, or even an acreage with several different types of weeds.

Best Weed Killer on the Market: Compare and Save Weed Killer, Concentrate Grass
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.
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.
Second Runner Up for Best Weed and Grass Killer: Roundup 5200210
If Roundup’s other products aren’t getting the job done for you, or if you’re simply looking for one that you don’t have to mix yourself into a sprayer, but still want proven weed-killing ability from a reliable manufacturer, Weed and Grass Killer III is worthy of your consideration.
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.

Make sure to wait at least a week before planting anything new, however.
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.

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.

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.

Winner, Best Budget Weed Killer: Fertilome 33692 Killzall Weed and Grass Killer
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.
Runner Up, Best Budget Weed Killer: Spectracide Weed and Grass Killer 2
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.

Winner, Best Natural Weed Killer: Bonide Burnout Natural Weed Killer
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.

The Best 2 4 D Weed Killers
For those that want to kill only weeds, while sparing other vegetation, we recommend using 2, 4 D weed killers. Below are our top picks.
Winner, Best 2, 4 D Weed Killer: Southern Ag 2,4-D Amine Weed Killer
A favorite among landscapers for years, Southern Ag’s 2, 4 D Amine Weed Killer contains a very potent blend of herbicides specifically designed to take out all the things you don’t want, while leaving your grass fully intact — even St. Augustine grass.
This product uses a 46.3% ratio of 2, 4 D, which makes it easy to stretch this one quart container into acres and acres of usage, especially when applied selectively rather than broadly.
In about 7 days, leafy broadleaf weeds will begin to die off, while your grass and other vegetation will thrive. This makes it ideal for use on golf courses, along fences and ditches, industrial sites, and of course your front and back yards.
Do keep in mind that this is a container with concentrate only, so you’ll need to provide your own mixing, and a means in which to spray the herbicide.
For just over $20, it’s hard to think of a more effective 2, 4 D weed killer for such an economical price. You get both value and results with Southern Ag’s 2, 4 D Amine Weed Killer, and I highly recommend it.
Runner Up, Best 2, 4 D Weed Killer: Fertilome Weed Killer
Fertilome’s Weed Killer is another excellent selective herbicide that achieves quick and sustained results, while boasting an ideal chemical ratio that allows it to target a variety of unwanted growths in and around your property.
This product uses 2,4 D at a ratio of 10.49% with small amounts of Mecoprop-p and Dicamba giving it a little more versatility than usual. Just 4 ounces of the weed killer can create 2 full gallons of herbicide.

Application is best done in dry conditions, and before the weather starts to get above 85 degrees Fahrenheit.
Fertilome Weed Killer is a bit more expensive than other products, but its potent and targeted mix of herbicides makes it one of the most effective selective weed killers you’ll ever use.
For those looking for a product that goes beyond just the typical weed control, Ortho Weed-B-Gon Plus Crabgrass Control is a worthy purchase that works in more ways than one
This product obviously uses 2, 4 D, but also has additional chemicals that specifically target unwanted crabgrass that can threaten to overtake your yard. And just like its selectie nature, you can apply to any areas with weeds and crabgrass, but without killing and of your normal grass.
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.

The combination of 2, 4 D and triclopyr have been delicately balanced for maximum efficacy, while still protecting your grass areas. If you have a large lot that hasn’t received attention for a while, or just have a large amount of sudden unwanted growth, this product can handle it all ith ease.
And while this may be just a 32 ounce bottle, all it takes is 1 and ⅓ ounce per gallon, so you’re getting over 25 gallons of herbicide from one bottle, and all for under $30.
