#1.Bayer Advanced Crabgrass Killer
If you want the best crabgrass pre-emergent, the Bayer Advanced Crabgrass Killer is the right one for you. This stuff works great on crabgrass and the toughest of weeds. We love the fact that it kills the crabgrass through the roots and does a really good job of not harming your lawns. One bottle is rainproof for 5,000 square feet and rainproofs in 1 hour.
Bayer Advanced starts working almost immediately and will not only kill crabgrass but also prevent it from growing. However, it is a more effective crabgrass killer than a pre-emergent. So all in all, if you use it correctly which basically means diluting the right amounts and not using too much, then it should be very safe to use on your lawn grass.
#2.Scotts Halts Crabgrass Preventer
Next up, we have Scotts Halts Crabgrass Preventer, which is the best crabgrass pre-emergent for those who are lazy and want to prevent crabgrass all season long. The way it works is that one application in the spring will prevent crabgrass and all other problem weeds all season long. Unlike the Bayer Advanced, this is more of a preventer and less of a weed killer.
We also really like the fact that this stuff is pretty weather resistant, so it will survive rain, snow, as well as extreme heat, and freezing weather. It truly is for the lazy man who just wants to set it and forget it. And besides, it is Scotts brand, which has been around in the industry long enough to sort of advertise for itself.
#3.Jonathan Green & Sons Crabgrass Preventer
Jonathan Green & Sons has always been a household name in the world of fertilizers and lawn care. This weed controller is definitely a quality product that we can stand behind. We think that it does a really good job of killing off crabgrass and making sure that they don’t come back again. In terms of performance, we rate it somewhere in between Bayer Advance and Scotts Halts.
We will fully admit, it is not as good as a weed and crabgrass killer as Bayer Advanced, but it is also a better crabgrass preventer than Bayer. Basically, we think that it does a fairly decent job at killing existing crabgrass and preventing new ones from growing. However, it won’t excel at either one.
#4.Ortho Weed B Gon MAX Crabgrass Control
The Ortho Weed B Gon Max Crabgrass Control is a very powerful weed and crabgrass killer that rivals Bayer Advanced. It fully lives up to the slogan it kills weeds, not lawns. While the Bayer Advanced does a better job of killing a larger variety of weeds, the Ortho Weed seems to work better on certain weeds and may even have a slight advantage on crabgrass.
The only issue we have with it is that it is not very effective in terms of controlling crabgrass and making sure that it doesn’t grow again. It works more like a one-time killer for crabgrass. Furthermore, application is really easy and there is even a nice little trigger spray that comes with the bottle that is ready to be used.
#5.Green Light 7462 Wipe-Out Crabgrass Killer
Lastly, we really like the Green Light 7462, which is a nice Wipe Out Crabgrass Killer. The active ingredients include 2,4-d, dimethylamine salt, quinclorac, and dicamba. In general, we find this to be a really powerful formula that works really well on crabgrass as well as on over 250 different unwanted weed varieties.
While it is a really powerful crabgrass killer and will absolutely wipe them out from the root, we find that it can also damage your lawn a bit and yellow your turf grass. You may be at the point where you might as well start from new and just use this to nuke your lawn and then re-grow your turf grass from scratch.
