    Is there a fertilizer that kills crabgrass?

    edit: Also, there are random brown spots showing up in my yard, is this a sign of grub?

    No, there's not a fertilizer that will kill crabgrass. There are pre-emergent fertlizers that when watered in and applied in early spring will prevent crabgrass germination throughout the season given proper mowing height, trimming, etc.
    You can try if you want to kill crabgrass. I'll put that in there because Norm Al doesn't want to sound like he sells it :)

    The brown spots are probably a fungal disease (red thread, dollar spot). Is it hot and humid in Ohio?

    As said pre-em like barricade, demension, team etc ,acclaim extra and drive are expensive options that can be used for post emergence control.

    sounds like you have brown spot, in the lawn. Drive 75 will smoke out that garb grass, its expense.

    Acclaim and Drive are the best post-emergent options, but they are expensive. I have actually had good luck with a PBI Gordon product called Tri-mec plus, it is good on most broadleafs (about the same as a normal 3-way product) but it also contains MSMA and at its high rate will kill crabgrass quite nicely. I don't know how they were able to mix 3-way and msma, as anyone who has tried it will tell you, they are not compatable, like smoke and heat everywhere until you are left with a solid.

    Some people confuse other types of grasses with crabgrass, too. So be sure you're treating crabgrass and not another type of invasive grass in your turf.
