I agree with what everyone's said - make her work or make her bump herself on the bit when she goes to root. Or, if you can, try to see what she does before she gets to that point and make her think of something else before she even gets there.
For instance, the mare that I ride will sometimes refuse to turn the way I want her to when I go back to the ring from a rest period in the middle of the arena. If she won't give to the bit, then we just do lots of tiny circles at a good clip in the other direction until I can feel that she's looking for an out, and then I take her back to the wall and have her turn the way that I wanted her to originally. Don't let her think that she can get away scott-free by misbehaving, and always make sure you get your way in the end.
Also, depending on what it is that she does, sometimes getting mad is appropriate. This same mare I ride doesn't like to have a lot of contact on the bit, and if she feels like the reins are too tight or she feels like being bratty (lately she's had a lot of energy and wants to buck a lot), she'll throw her head down and out to pull the reins out of my hands. For a while I just took them back and didn't let her win, but at one point she almost tore me out of the saddle and she got a good smack for it. You need to let them know that enough is enough. The intensity of your corrections need to correlate to the intensity of their misstep.
