I wish to inform you of the misinformation in your article titled "Hairy Bittercress Killer: Learn More About Control For Hairy Bittercress" This plant doesn't have a tap root and can be easily and effectively hand pulled before the seeds have ripened. Did a chemical company sponsor this article/website?
Yes, hairy bittercress can be pulled easily. So can garlic mustard and it has a taproot. However, I have seen hairy bittercress in lawns where there are hundreds of tiny plants that bloom when only 1-2 inches tall. Mowing doesn't reach them. Where hand-pulling isn't feasible, a homeowner has the right to select an appropriate herbicide. This website simply provides information as best we can.
Hairy Bittercress has appeared in Northeast Ohio the past couple of years....I know I have to kill it before its seed pods explode, causing more bittercress.

I have a bank on which we cultivate Vinca for erosion control along with mulch. It has been invaded by Hairy Bittercress to an extent that pulling all of it is impossible. We've been trying. Is there anything that will kill the bittercress and not harm the Vinca (periwinkle)?
Unfortunately, any broadleaf herbicide will target the Vinca, as well. What I could suggest is to dig up a few patches of Vinca and kill the entire area with an herbicide. Once you have given it a few weeks to clear off, you can replant.
Another option will be to dig up a few plants to replant, then kill the entire area with boiling water, or solarization. These two methods will leave the soil plantable, immediately, after treatment.
