2-4D or a three way will take care of it.

Grandview, what are you referring to with your idea? I have no idea what you're talking about. Obviously, I'm a bit new to all this, sorry.

Foreget Walmart, Lowes, Homedepot, Target and about any other big box store!
Go to a feed store or real good garden center. Look for Southern Ag Lawn Weed Control, Trimec, or something like it. Look at the ingredients; you will see scientific names:
2,4-D ethylheylr--ester
Mecoprop-p acid
Diacamba acid
This combo is know as three-way. Some like Speedzone and lots of other have other stuff in them. There's a lot of inert ingredients that act as binder or suspension materials to keep from clumping together that most of us do not need to memorize their names but are available.

Mustard is a broadleaf plant like plantain, dandelions, etc that a Three-way controls kills by starving the roots, prevention of photosynthesis, growing the plant to death among others.
Most of the Three-ways are temp effective--that is some will hurt the grass after about 90 degrees, some will not, some will not work below 50, some will and on and on and on. So, in the final analysis, select one that will kill the weeds listed or the guy at the counter recommends (Sometimes the worst advise) but you will get a fill. The application is generally stated by how much product (Trimec) will be put on 1000sq.ft of lawn. Water is sorta arbitrary. Most of us use about 1 gal or just a shade over to cover 1000 SF with our chems (1 oz. or recommedation from factory) This is not the easiest thing for a beginner to do. You may elect to let one of the pros in your area to do it. If you've only got a few of those mustard plants, wait till after a rain and pull them.
Hope this helps,

However--what kind of mustard are you talking about? Garlic mustard? Hairy cress? Grey Poupon?
Do you have a picture? Mustard is easy to kill--not many lawns have mustard.

Does it look like this?

Riggs: I believe that it's the old tall yellow, milky green leaves that he's talking about. It is basically planted as a cover crop for planted fields. We've got plenty around here in TN. However, we very seldom get the grey poupon or the Spicy German variety for our Southern Style Barbecue County Pork Ribs. One mouthful of these and you just know you've died and gone to heaven.
