20 Best Kill Everything Weed Killer (2023 Updated)

I’ve used other weed and grass killer products that gets rid of unwanted grass and weeds but never yet had I found a product that kills down to the root as advertised. Spectracide® Weed & Grass Killer Concentrate2 does as advertised.

I did a spot check in my flower beds to get ready for next spring and wow it did a great job. The unwanted grass and weeds were yellowing after a few hours and brown by the next day! Being that the solution was concentrated and there was an AccuMeasure system with an easy-to-use cap, it took the hassle out of measuring and mixing the concentrate formula; so I was able to get just enough to try it out in a small area.

In my next use I tried it on a larger area and got the same results. I also love that I still have a lot of formula left over even after I treated my driveway, walkways, and sidewalk. I’m overly pleased with this product and have already recommended it to family and friends.

I was provided a bottle of the Spectracide Weed and Grass killer concentrate to try and provide my thoughts. I have a lot of creeping charlie that has taken over my backyard. Literally it exploded from a 1/4 of my back yard to almost the entire yard this summer, from 1 week to the next.

We have had a drought for a while and then had a lot of rain. By the time we were able to get into the backyard, the creeping had crept up and killed almost any and all grass and made it either creeping charlie heave or bare dirt spaces with creeping charlie nearby.

I felt this would be a perfect opportunity to try and provide my thoughts. I cannot attest to grass, and I didn’t have grass yet to kill. But, we put this into the sprayer, did what we needed to make this sprayable and went to town.

Spraying the areas, away from the dog potty zone and waited. It was a nice sunny day, low to mid 80’s and no rain in sight. Waited. Later that day, I felt like it looked like a lot of the charlie had died.

But, thought it might be my imagination. Waited next couple of days, watching. Noticing more and more browning and death to the creeping charlie. Mind you, I had one application at this point, and find that the first past, killed quite a bit of the charlie.

I feel with another couple of passes of the Specracide, I might win this season’s war of the creeping charlie. I liked this, fairly easy to use, appeared to start killing pretty quickly. I would be happy to try more to see I this turf war can be won by us and not the creeping charlie.

I fight a constant battle with my driveway. It’s a nice long stone driveway — however grass always seems to want to grow in it. I buy quite a bit of weed killer to spray in the driveway to keep the grass under control and it gets expensive and the premixed sprayers are not very efficient.

This Weed and Grass Killer Concentrate has helped on numerous fronts. 1) I was able to buy it online. Since it’s concentrate, the container isn’t very large (which is good!). It was shipped in a reasonably small box and was wrapped in a sealed bag inside.

This is convenient, since I didn’t really know what to expect with shipping something like this. 2) It has clear instructions, measuring cap and is easy to use. I got this to mix myself in a larger sprayer — worked like a charm.

3) It’s more cost effective than some of the other pre-mixed + sprayer container options I was trying. Once I filled up the sprayer with the weed and grass killer, I went out and sprayed my lawn more effectively than past use with the other sprayers, finished in less than 1/2 the time and then waited.

I saw clear results of dying grass within a day. Do I recommend? Yes — if you want a grass killer concentrate, then give this one a try.

This is good weed and grass killer concentrate. I like buying concentrate because you don’t pay as much for the water that comes in the bottle. This Spectracide concentrate worked better than I thought too.

I used less than the recommended amount (I mixed 6oz of Spectracide with 1 gallon of water) and it annihilated all the unwanted grass and weeds I had around my raised flower beds and sidewalks. I could see results in about 8 hours, but the grass was brown and completely dead within 24 hours (I was impressed with how hard and fast it worked).

I usually use Round Up, but I will continue to use this Spectracide because it is cheaper to buy than Round Up, and it works just as good.

For those that say this product does not work i say read and FOLLOW the instructions. I found that if you apply this product mixed 1. 5 to 1 and spray it in the late evening because plants take up moisture through their leaves at night and it cuts the kill time down to half.

I use this stuff on Goat heads and it kills them dead. It kills everything for a price that does not break the bank.

I purchased this product on 5/13/22. I have a spine problem so I had to hire a yard man to come out and spray my beds. The fisrt visit he charged me $40. I watched as he sprayed well the entire area.

On the bottle is stated: visible results in 3 hours. I went outside in 3 hours and nothing! No results whatsoever. I went back in 6 hours. and Nothing. I continued looking for a couple of days to no avail.

It did not kill any grass or even the tiny weeds that were visible. I called the company after several days, and the customer service rep checked and returned to the phone stating it might take up to 2 weeks total.

I waited longer and then had the yard man come back and respray to no avail!. This time he charged me $60. During that time it was very hot, dry weather, and the weeds should have died by then. I saw a tv ad yesterday for this product which stated, GUARANTEED RESULTS OR YOUR MONEY FULLY REFUNDED.

! I have now spent $100 to spray these few weeds and grass + a total of $17. 17 for the spray, making it a total of$117. 11. Today it has been 2 wseeks adn 1 day, since he first sprayed with no results!.

I had a bad experience with the 1 gallon size Roundup premix with the electric sprayer wand included in the package. The sprayer wand, even on the high volume spray setting barely put out a small amount of liquid.

I had a patch of about 10 ft by 10 ft that I wanted to spray down. I use this battery operated on to spray for about 45 minutes and it barely emptied 1/4 of the gallon container. It just did not put out a reasonable amount of spray to get anything done in a reasonable amount of time.

Compared to my one gallon hand pump sprayer this put out about 1/8 of the amount. The marks on spray tip show three streams coming out and that’s what I had but it very low volume. I would not buy this again just because it wastes so much time trying to spray with a little tiny squirt.

We have a small farm with a very long, and large, gravel driveway. We use this once a year to control grasses and weeds that grow in the gravel driveway as well as controlling grasses around our barn, under our trees, and on the sidewalks.

This also knocked out poison ivy in a few spots if applied thick enough. Combined with a Stihl backpack sprayer, we couldn’t be happier. For mixing, add water slowly as others have suggested. It will foam with fast water flow and can overspill if not careful.

When applying, we walk backwards and spray in front of us to prevent walking through the chemical. One bottle/container covers everything we need. We’ve applied annually for the last three years and have noticed less and less return growth.

Results are noticed in a few days.

I have used Roundup on my property for about the last 5 years. I like the product but there are major issues with material. When I bought my first container with a sprayer, it worked very well. I used it immediately after purchasing it from Home Depot.

The next year I still had the spray container, so I purchased the refill container and the material worked fine. I also needed more material and I bought the super concentrate so that I could mix my own material At the end of the summer I had used only half of the material, and so I kept the spray container with the product in it in my garage over the winter.

My garage doesn’t freeze, since it is attached to the house. The next spring, this year 2021, when I tried to use the sprayer, it didn’t work. I opened the container and found that the product had jelly lumps in it and therefore they were clogging the fine openings in the sprayer.

I cleaned the sprayer and screened the product. When I sprayed it on the walkway weeds nothing happened. The material had lost its potency. I read the labels on the containers carefully and found no mention of self life and also proper conditions for storage of the material.

So I bought another container of Roundup with a sprayer on it. The newly purchased product worked wonderfully. However, I needed more, so I made a new mixture from the Super Concentrate that I had purchased two years earlier.

When I used it, it did not work at all. So there is a self life to the super concentrate. That really troubled me, because the Super Concentrate cost about $73. 00 when I purchased it. So my questions are twofold: 1.

Why is there no statement on the containers that state there is a self life associated with the product; and 2. Why is there no expiration date printed on the container. This is really a lack of sensitivity to the residential customer.

I finally wet on the web and read a lot of reviews. The jelly effect isw known and posted on various sites, but the RoundUp website does not give one proper storage conditions. Further reading lead me to a statement several layers deep into the RoundUp website that the shelf life is 4 years.

That is a meaningless statement, since they do not give you the storage conditions used to develop that number. When a residential customer buys the product from a retail store, there is no indication as to how old the product is.

And for the residential user, that has stored the material along with other gardening materials, there is no way of knowing the effectiveness of this product. The labeling and instructions really need to be vastly improved.

As a final note, I have read many of the reviews posted here. People who use the product when it is potent, get excellent results. But other individuals present information that indicates that they have product that is past its shelf life and found that it does not work.

As a result the distribution in ratings is bimodal.

I bought the super concentrate at a local Ace store here in Nashville. I had previously used the concentrate plus with very good results but opted for this super concentrate because it was going to mix more product.

Well, after mixing according to label, 2. 5 fl. oz/1gal water, I made 6 gallons of this stuff and spent no less than a couple of hours spraying everything from grass, weeds and plants. It’s been over 48 hours and there’s not a single brown and/or withering plant or blade of grass.

I spent $20 more dollars to get this super concentrate over the concentrate plus and I guarantee you I will DEFINITELY not be buying this again.

I really liked the side holster comfort wand. There was no pumping to mix the ingredients and it is so easy to apply. You can control the spray to desired amount and just squeeze the trigger to coat the leaves of the weeds.

As advertised, there was no damage to my Bermuda lawn. But it only wounded the weeds and did not kill them. I applied it more than once at the recommended times. After reading all the literature, could only fulfill part of the conditions.

It is very humid here and the yards are mostly damp. Our temperatures are well above 100 degrees for much of the day and it is the dead of summer instead of fall or spring. So my weak results could be caused by the wrong conditions.

I do use other Ortho product that have worked quite well. We just moved from a Kentucky bluegrass lawn to a Bermuda lawn and we are just learning.

Great stuff, and it works really well in south Louisiana’s tropical climate including poison ivy. Great price. Quick delivery. Happy with purchase.

3 months after i paid a yardservice to kill the weeds. It looks like it was fertilized. Disappointed. Angry

I sprayed diluted roundup solution around the trunk of my oak, green ash trees and roses to remove weeds growing in this area (also called area inside the drip line). The herbicide effectively killed all the weeds in this area: the weeds dried up and turned to a beige color.

Unfortunately, the chemical also caused some damage to the oak, green ash and roses: their leaves became twisted and leaf growth was stunted. The upper part of some rose trunks died as well. It was indeed noted on Google that these chemicals can damage the roots of plants or trees that have shallow roots.

It is a great product for killing weeds. Just be aware about not to apply directly around or too close to trees. I think such a warning on the label would be very helpful to users.

I followed the instructions to the letter. 2 beautiful days before and after application. More weeds pop up and the ones that recieved treatment just grew larger. I believe spectracide is an inferior product for the asking price that this web site will not allow to be shown.

I suggest ortho products replace spectracide. I wish I saved my reception so I can demand a refund. I do have the 2nd. bottle left. What a waist of a bunch of money.

I used this last spring and it did a fabulous job at weed eradication and I had a beautiful green lawn once the Bermuda grass came in. My lawn thickened up the turf well. I used it again yesterday and 29 hours later the weeds are wilted and limp.

It’s too early in the season to evaluate the turf. But I anticipate good results as I received last year. This has been much more cost effective than granular products.

Undecided how to rate, but, it’s been 5 days now since application and not seeing ANY signs of weeds even getting a little bit “limp” or “sick”. Maybe I expect too much too soon, but seems like they should at least not look so healthy after five FULL days.

Maybe I will be surprised and have to edit this review. Obviously did not expect the “feed” part to do anything this soon, but expected the weeds to at least look “not well” !.

I use this weed stop in my hose dispenser. I sprayed my lawn and didn’t notice any different I have a small palm tree that has weeds going all on the front of it. I sprayed it and 24 hours later it started to wilt.

It slowly dying. It may have worked okay on my lawn and I just don’t notice much of a difference because it’s camouflaged by the grass. It did not kill my grass which is a good thing. I think it works better on standalone weeds like the one that is growing in front of my small palm tree that has pictures included.

I wouldn’t say it’s the strongest weed killer out there but it’s also weak enough not to kill plants that you don’t want it to kill. So it’s just an average weed killer. I live in Florida where it’s warm most of the year and weeds grow all year long.

I tried using this product on cooler days. I think I might have had better luck on a very hot day where the sun might help kill the weed by cooking the chemicals.

What I like the most is the spray attachment; it takes the guess work out trying to figure water to concentrate mix. Making each spray the exact amount of product you need. You end up getting the most bang for your buck.

You get about 16,000 sq feet with this so it goes a long way. I like that it seemed to attack the weeds and not my grass. Took a little over a week for our mild weed issue, but Dandelions have become almost nonexistent in my yard which my sinuses appreciate.

I found the sprayer to be easy to use and easy to attach to my garden hose. I will be using this on my lawn again.

This stuff stops weed problems in very short order. I use it around fencing; on the outside of garden pavers; under our front porch; and yes, directly on our lawn. In my experience, this pretty much fully eliminates weeds in any area it’s used, within days.

This does not have a very strong odor to it. Also, you get a lot of mileage out of this since it’s a concentrate. Overall: In my opinion, this is the best concentrate available for common weeds. Highly recommended 5 stars Cheers!.

I will buy it again because it is the best deal in concentrate weed and grass control – when I did the math as to how much is needed to make X amount it is the best bargain. I dinged a star for the odor which did permeate the air from many feet away.

The neighbor even shut her door in disgust as I sprayed, it was evening and even without wind the smell just carried. I recommend we wear a mouth and nose-covering filter mask and plan on staying away from the area after spraying, at least until it dries.

I have used other brands extended for a long time, before they made extended I used the regular, always the concentrate. I never had noticed that much BAD odor with that line, so this surprised me. That said, in a couple of days all the weeds and grass were DECIMATED to nothing.

Not just dead, but dead and pretty much gone.

I mainly use this product to control part of my garden bed that I want to be free from any vegetation. I have used competitor product previously and the result wasn’t satisfying as the weeds/grasses has grown back after short period.

With Spectracide extended control, the chemical seems to react faster. I can see the weed leaves wilted after few hours of spraying. The extended control can go up to 5 months which gave me a lot of promise.

Just make sure to apply this weed and grass killer when the temperature is warm. The toxic warning seems to be less than other product, however, applying this chemical using dial type hose end sprayer can be a bit difficult to control from overspraying to surrounding plants.

Let see if this product can live up to its promises after few months.

Weed and grass killer W/ extended control concentrate This concentrated weed killer kills everything. It kills roots, grass, and weeds. It’s extended control so it protects from coming back for up to five months.

You should be able to see it working in about 3 hours. It is better if you use the weed killer in weather above 60 degrees, and it is rainproof in about 15 minutes. I use it on everything; my flower bed, shrubs, trees, on my patio, walkways, driveways, and along my fences.

Pros of this product is that it works fast and for a long time. Cons of this product is that it kills everything so be careful around grass you want to keep.

Spectracide Weed Stop for Lawns is an overall good product when being judged by just the product and not the provided bottle spray adapter. Although the initial setup was very easy to do, after attempting to spray a garden bed with flowers, the spray nozzle leaked all over my hands and arms cause slight irritation to the skin.

In order to properly use this product, I had to dump the contents into another off the shelf chemical sprayer for use. After doing this, the results were not only satisfy and immediate, but killed off only the unwanted weeds and not my flowers.

Also it did as it says. within 3 hours I did notice the chemical working its magic!.

This product worked fairly well. I did notice we had to use a lot to get it to work. We had to spray several times in the same spot in order for the weeds to die. They did however eventually die. I also noticed it wilted some weeds instead of just killing them.

It sprayed easily without clogging up. I love that I can easily spot spray the weeds without spraying it all over my lawn. Overall it did what it was supposed to just wish I didn’t have to use so much of the product to accomplish this.

Our yard is almost entirely Saint Augustine grass and with the extra moisture the past few weeks, we have had some clovers and dollar weeds popping up! I grabbed the Spectracide. The bottle design is super easy to use and the spray is ready to go right out of the bottle (no extra steps).

I love the spray nozzle that allows me to focus right on the weeds. However, after a few days, the spots I sprayed — the grass was dead. Disappointed, but glad I only did a few spots!.

Have been using Roundup QuikPro for several years now. Pros for this herbicide is that it goes inactive when it hits the soil, so no residual in the soil. It does not affect my trees when the mix hits the trunks or exposed non-feeding roots.

I can mix it with Triclopyr when I need to save time and kill everything, although some care is necessary because the Triclopyr has residual in the soil. The Diquat hits the weeds quickly, so I can tell areas that I have missed without using a dye and can reapply on spots.

The original Roundup formulation did not have the Diquat, so you had to wait for a week to see missed areas or a dye must be used. Cons, I have just one, some of my weeds laugh at it and I need to use the Triclopyr.

Caveat: I have not used any other brand of Glyphosate formulation so have no basis for brand comparison.

This easy mix and apply formula is one of the best weed control products on the market, bar none. Do not be fooled by the water downed formulas you purchase at your local home improvement stores, it is not the same.

This is a easy mix granular formula that mixes into a slurry mix, then when the rest of the water is added turns into a weed killing application like none other. I honestly suggest this product for residential or commercial applications.

Caution: you must apply to dry area, do not allow product to get wet from rain, sprinklers or hand watering at least two hours. You will see results within eight hours and thwarts off weeds for six to eight weeks.

The 6. 8 pound container makes 100 gallons of mix. No need to add a little, more mix to less water doesn’t make the solution stronger, just wastes your hard earned money, don’t be tempted to do such a thing.

The weapon of mass weed destruction. Best thing is that its in a granular form, so its cheap when you figure out the cost per oz vs gallons mixed. 1oz dry granules to one gallon of water and the weeds don’t stand a chance.

Works very quickly and I highly recommend this product, pro grade.

Gonna start with -“l severely despise weedeating!” I dislike pulling weeds by hand even worse. I was having a hard time trusting the “kills the weeds and not the grass”. I don’t understand how it knows the difference.

Most of the people I deal with on a daily basis aren’t that smart lol. Well, I have this are in my front yard that I like to keep looking neat and kept up. it’s the first thing you see when pulling up to my house.

I decided to trust the process. Day 1 after spraying (we are in a drought so everything is dying anyway… well, except the weeds) , I noticed the wilting and nothing around the actual seeds looking sick.

I thought “that’s cool”. Day 2 just the weeds starting to turn brown and wither down. So I guess I a say that it works without killing the grass. I’m going to give another treatment next week to catch them crafty ones that were hiding.

I think I like this stuff though it’s so convent to pick up and spray … no mixing or anything else. Just grab, go, and spray!.

I applied this about 4 days ago and I’m still waiting for the weeds to die. Some of them are starting to look a little sickly so I’m hoping those little suckers will just go ahead and die really soon.

I love me some Round Up and Remedy, but I’m trying not to use as many super heavy duty chemicals, especially around my yard and flowerbeds. I’m used to overnight results with those, but I’m hoping this Ortho WeedClear eventually comes through for me.

The great thing about this is that it doesn’t kill EVERYTHING it gets on. It also gets bonus points for being easy to carry, being premixed, and having a battery powered wand that I can replace the batteries in if they run down! It also has this nifty little strap on the side to hold the sprayer and hose when you’re not using it.

I’ve given this product a try on my weeds. For starters, I really don’t mind weeds, they are often green, and grow with the simplest of ease and require no water. That being said, I have a couple of areas that I like to keep the weeds under control, basically the places that the lawn dude doesn’t mow.

I’ve used this product on my cement driveway cracks. The grass that has grown there continues to thrives, the other weeds where gone within a week. I have one very stubborn weed that insists on thriving.

I have been trying to get ride of it for over a year, after applying this weed killer,it began wilting within a couple of days. I really like the dispensing system. I don’t have to mix or pump anything.

It is a simple set up and very simple to store as well.

I do not know where all the favorable reviews come from. I read the label completely, applied exactly as directed on partly cloudy day with a temperature of 68-70 degrees. No rain, no watering for 6 days.

Product did nothing. Not a single weed even turned yellow. It was as if I sprayed water on them. I measured each area of my yard with my measuring wheel prior to purchasing so I knew I needed 3 bottles to cover my yard.

After completion I had about 2 oz. of product left so application amount was spot on. And the “Money Back Guarantee” listed on the front of the bottle. Good luck with that! I found nothing about it on Spectracide’s website.

Even using their search returned their Privacy Policy. I’ve had good results with other Spectracide products but this one literally did nothing for me.

It works well on clover and dollar weed. So far, I can’t tell if it works on anything else. Note that this weed killer takes time. Not like northern grass weed killer that shows it working sometimes overnight.

In maybe 4 days you start to see clover turning a lighter shade of green then eventually yellow until gone so give it 2 weeks. You can also re-apply after a couple weeks if necessary.

We have an 18×10 area that is mulched and covered in crafted metal animals and lawn art, antique ox pulled plow, carousel horse, etc. It doesn’t look great when it is covered in weeds that grow through the supposed weed mat.

I tried the normal ground clear products and no results. Then my Tractor Supply associate told me about this product. It works like a charm! In a few hours, start to see a little brown in the weeds and in two or three days everything’s dead.

I use it 2x a year and no issues. I also use it on our parking pads, flagstone patio, sidewalks, and in our mulched backyard area. While it seems more expensive, it really isn’t, because you mix it with water, so you can make gallons of it for your sprayer.

7. 4 fluid ounces of RM43 per gallon of water, up to ten gallons, with a maximum application rate of 7. 4 fluid ounces of product per 1,000 square feet (2. 5 gallons per acre) per year. 74 x 0. 125 = 9.

25. 9 and 1/4 cups RM43 + 10 Gallon of water in my 10 gallon pull sprayer. Used for Kudzu. I can’t possibly spray the entire kudzu field below my property so I sprayed just along the edge to try and keep it back.

New kudzu grows right over the top so I think just keeping it mowed back works better and less expensive. This spray will kill everything.

This stuff just flat out works. Like many have said, it takes a bit for it to show results, but rest assured, it will kill whatever you spray it on provided you FOLLOW THE IMSTRUCTIONS on the label. I guess some have quite unrealistic expectations but hey, it does the job and you save a bunch of monye vs the Big name brands.

I mean isn’t the point that the weeds end up dead? You cand overspend if you wish or you can save money. Either way the weeds end up dead. Not a hard choice for me. Don’t listen to anyone who says this stuff doesn’t work.

They probably expected way faster results and were disappointed at the speed. It kills weeds. PERIOD.

Can’t get this in our local stores anymore. I still need to take care of our estate and that means getting rid of vegetation overgrowth. This stuff does the job like no other! Mix 3 ounces to a gallon of water, add a little surfactant (I use Dawn soap) spray it on the leaves of the undesired vegetation.

all dead in a few days. Used it to kill several small trees as well. It’s great stuff! Its 41% glyphosate and it works. Great price too! 2. 5 gallons should last a while but I’ll buy several more before the end of 2021.

They will probably outlaw it like everything else. Buy some today, keep your yard looking great!.

Can’t beat the price. But using it without the understanding that it takes a long time to kill weeds may lead you to think it doesn’t work, or that you did something wrong and apply more than you need.

I’ve applied it to crab grass, Bermuda grass, plantain, lespedeza, clover and other weeds. The next few days, the weeds look as healthy as the day I sprayed them. It took a week or more for the weeds to look like they are starting to die, and a few days longer than that for them to die completely.

So this stuff does work, but if you’re expecting overnight results like some big brands do, you’ll be disappointed. Soak the weeds, and come back a week later to see the results.

Worked great without all the negative effects of Roundup

With small pets it’s essential to have non-toxic products for the home & garden. A product that works in a day without damaging the environment…take my money!
