Somebody ID ma Weed

No herbicide will knock it out quickly and permanently. repeated applications of an herbicide that contains 2,4-D (Weed-B-Gon, Weed Stop, Wipe-Out, etc) will control it, particularly if you start spraying when the weed is young.

The yellow, ball-like seeds of niruri develop under the leaves. They need very warm soil in order to germinate so you won’t notice the seedlings until mid-summer. Researchers say pre-emergence herbicides that contain atrazine (Purge) on centipede lawns and isoxaben (click for sources)

on all turfgrasses give good results when applied in early May.

Thank you gents. My lawn looks stellar this year aside from this stuff.

Did lawn care for 7 years. Everyone is correct about it being chamber bitter. Spectricide won’t touch it. Dismiss has been about the best thing to use for most all spring/summer weeds. It will take a minimum of 2 applications to get rid of it.

You shouldn’t have planted the China seeds.

I have a 2 foot wide decorative stone border around my house and this stuff has been coming up. What I did was pull the weeds and sprayed the stone right after doing so with Ortho Max Poison Ivy and Brush Killer. (I call it Agent Orange) I tried it in a small patch and it works real well. I know this doesn't help you with the lawn, because the mix will kill everything it's sprayed on, but it does give you an idea of what you're dealing with.

Think I’ll start with the 2-4d. I can squeeze that in the budget. Unless someone will ration me a few drops of Dismiss. Holy crap that stuffs expensive.

I have one of their tip n pour bottles and it’s lasted me 2 years so far. Do NOT use 2-4d to try and control chamber bitter. You will be waisting time and money. 2-4d is good for basic broadleaf weeds. Dismiss will take care of majority of stubborn weeds during this season. Just know that 1 application will not a lot back but not 100%. You WILL have to go back a second and maybe a third time to kill off. A lot of weeds have a large root system.
