We’ve been dealing with weed killers for a couple of days. During our tests, we had to see if the weedkillers are great for centipede grass. Now, we had lots of options in our hands, and surprisingly only 8 of them hit the mark.
Their functionality also changed based on their types. Some of them were safe to pets and children, while others were not.
Despite some problems, they helped in pesticide spray penetration, had multi-functionality, and the growth acceleration of the grass was great.
Now, it was tough to get which is the best weed killer for centipede grass since almost every weed killer was good. However, we did try to give you a hint.
Read the reviews, and you’ll know better.
8 Best Weed Killer for Centipede Grass
It's time to get into the actual business. We've found the top 8 weed killer for centipede lawn that we think you'd find helpful for your lawn. Want to have a peek? Then let's get started.
1. Southern Ag Surfactant for Herbicides
We call weeds the headache of a lawn, which ultimately makes it yours. So, it would be best if you had the right med to eliminate it from the route, and the first name that came to our mind for that is the Surfactant for Herbicides from Southern Ag.
The perfect chemical combination has made this weed killer simply perfect for stopping weeds. And yes, just like the best herbicide for centipede grass, it's also helpful in eliminating insects and fungus.
If you're thinking of a Non-Ionic surfactant, it only boosts up the coverage; then you're mistaken. It increases the penetration of your pesticide sprays at the same time. Plus, due to its lower price, you won't have to expect too much pressure on your wallet.
You don't even need to use too much of it to get started after mowing. If it's for Herbicides, use one teaspoonful/gallon, and it's the same for roundup usage too.
But when it comes to MSMA herbicides usage, you'll have to maintain a ratio of one tablespoonful/gallon.
Still, if you've got any confusion about the usage ratios, the makers have kept them all written on its 16oz/1 Pint gallon label. Just have a peek at it.
Pros
- Chemical combination helps in taking down the weed, insects, and fungus
- Increases pesticide spray penetration as a non-ionic surfactant
- It comes with a detailed label that keeps the usage instruction clear as a day
- The lower price keeps on the list of affordable weed killers

How to Choose the Right Centipede Grass Weed Killer
Remember, you’re here for the right weed killer. But once you make a wrong move, you won’t even know when that very chemical you’ve brought in becomes your centipede grass killer rather than saving them.
So, you need to make sure that the one you’re grabbing will save your lawn and only make it better without ruining it.
But how will you know whether it’s a killer or saver? Well, check out the following things, and you won’t have to worry about that even a bit.
Weed Types
There are hundreds of types of weed you’ll see out there. But that doesn’t mean all the weed killers come with the guarantee that they’ll kill them all.
So, to be sure of that, check out the types of weed it’s covering, whether you’re asking for a solution for your grassy weeds or thinking about broadleaf weed control.
If you’re not new to the whole lawn thing, you probably know what kind of weeds often attack your turf, whether it’s winter weeds or other common ones. No matter what they are, please make sure the weed killer got their name on its list.
Lawn Safety
You don’t want to see your beloved trees or grass die in the effort of getting rid of the weeds, do you? We guess not. So, you better be picking something that can keep the weeds out of the picture without hurting the trees or grasses.
Pet and Children Safe
Do you know what kids and pets have in common? You can’t always control them both from jumping on your lawn. As you can’t always keep them away from there, you better get a weed killer that will not cause any damage to them.
Now the question is, what will you do if the one you’ve chosen got it all but can be harmful to pets/children. Well, the only answer for that we’ve got is to keep both of them away from the lawn.
Coverage
No matter how good the weed killer is, it won’t be good enough for you if it can’t even cover your whole lawn. So, check out if the amount of liquid you’ve got in the container is sufficient for your lawn or not.
One more thing! We say rather than going for a one-time user, try to pick up something with a higher quantity as you don’t want to go for repetitive purchases every one/two months.
Ease of Application
We don’t think you need the details on this part. After all, no matter what you buy, you think of this one in the first place. So, feel free to go with a weed killer that doesn’t make you get a ton of other things to be applied over your lawn.
Diluted vs. Ready-to-Use
Both of these have their pros and cons. So, it depends on you which one you think is better for you. When it comes to the diluted ones, you’ll have to mix them up with a certain inch of water or the other chemicals. But this way, it’s possible to cover more areas easily.
But for the ready-to-use ones, you’ll have to apply them directly without any extra mixture. It’s less time-consuming, but you can’t use it in bigger areas like the diluted ones.
Longevity
You might be planning on lowering the centipede grass pH right after you take care of the weeds. But you’ll have to accept that headache once again if you don’t focus on the longevity of the weed killer.
So, before you swipe your card, check out for how long that chemical will keep the weeds out of the lawn.
How Do You Kill Weeds in Centipede Grass?
In a single sentence, the answer is using weed killers. But that’s not the answer you’ve been looking for.
If you’ve gone through all the weed killers that we’ve talked about, you’ve probably noticed that not all of them work in the same way. Some of them are diluted, and some are ready-to-use.
When you’ve got the diluted liquid weed killer, you’ll have to mix it up first with a certain amount of water.
Right after that, you’ll need to put it into a sprayer and keep spraying over the centipede grass while walking backward, as you don’t want to walk over the weed killer.
You don’t need any extra mixture of water for the ready-to-use kind and can apply over the grass right from the container. Some of them even come with a sprayer attached to the container. For these, you don’t even need an extra sprayer to get started with the work.
But if the weed killer is of Granular type, you’ll have to go for the same usage pattern as the liquid to kill the weeds. But the good thing about this one is that you can also use a sprayer or spray trolly to execute the task.
We suggest using the spray trolley due to two reasons. One, you can cover a larger area faster. Two, it’s comparatively hassle-free.
Final words
The prime purpose of our reviews is to get you the best weed killer for centipede grass in order to keep your lawn as safe and good as new. But if you’re still feeling stuck, we say focus on nothing but your prime need.
If you’re thinking about covering maximum weed type, then go for the Greenview Broadleaf Weed Control. But when you’re planning on covering different types of turf at once, think about nothing else but the Southern Ag Lawn Weed Killer.
Now the question is, which one would you go for when you want something to make the grassroots stronger and grow faster? Well, we can’t utter a better name than Scotts Turf Builder Weed and Feed 3 for that.
