#1.Surflan A.S. Pre-Emergent Herbicide

For those who are looking for the best pre emergent for st augustine, we highly recommend the Surflan A.S. Pre Emergent Herbicide. This herbicide does a pretty good job in annual grasses and many broadleaf weeds. This is a well known herbicide for established warm session turf such as st augustine grass. It will last up to four months and has very good coverage as well.

We should also mention that this stuff is expensive but it works very well. In fact, it is pretty industrial strength compared to other brands. Just don’t expect it to work on existing grown weeds. All in all, we would say that it works extremely well for tough weeds but it goes on really messy as it is bright orange and is probably not good for the environment.

#2.Scotts Halts Weed Preventer For St. Augustine

Next up, there’s Scotts Halts Weed Preventer, which is the best pre emergent for st augustine because it is Scotts brand and they pretty much do everything well. You can apply this stuff in the spring to prevent crabgrass and apply in the fall to prevent moss. Also, you can prevent problem weeds all season long.

But we are not going to lie, the main reason we really like the Scotts Halts Weed Preventer is that it is a Scotts product. And Scotts has been around in the industry for a really long time. They definitely know what they are doing and are pretty reliable in terms of quality and performance. Basically with Scotts, there is very little chance your st augustine will die.

#3.Concern 97185 Weed Prevention Plus

Another great option when it comes to the best pre emergent for st augustine is the Concern Weed Prevention Plus. We like it because it is a pre emergent herbicide as well as a 8-2-4 lawn food. One bag will cover around 1,500 square feet total and will not burn your lawn. it is also super effective in weed control and works especially well the very first year.

Perhaps our favorite part of this product is that it is a 2 in 1, so it definitely saves a lot of repeated work. It is also natural, harmless, and quite easy to use. We find that the weed control is pretty good and especially on warm weather turf like st augustine. However, the fertilzier could use some improvement, but we would view it like getting it free as an add on.

#4.Drive XLR8 Herbicide For St Augustine

There is also the Drive XLR8, which is a herbicide for st augustine grass and is quite possibly the best crabgrass killer on the market. Like the Surflan A.S., the Drive XLR8 is also quite industrial strength and you should probably wear some gloves while dealing with this stuff. It is a faster more complete weed control than others.

We really like it because it has a much quicker uptake by plants, which basically results in a much quicker kill. And one treatment is all you really need and the crabgrass is gone. The only issue we have with the Drive XLR8 is that it is so powerful that your st augustine grass will even suffer a bit. But it will grow back up without all the nasty weeds and crabgrass.

#5.Syngenta Princep Liquid Herbicide

The Syngenta Princep Liquid Herbicide is certainly an industrial strength herbicide that should not be ignored. It works really well with st augustine lawns and is right up there with Drive XLR8. What it does is that it enters the weed through the roots to inhibit growth. We find that it works well against grass burs, broadleaf and grassy weeds but you need to apply it early in the spring.

Although it is a little pricey, we think you are getting pretty good value for it considering the alternatives are just not as powerful. Unfortunately, it leaves a white residue so be sure to spray carefully. So all in all, the Syngenta is definitely a nice spray to use if all your other options have failed or you just want to try something new.
