vicious, hard to identify texas lawn weed
Ok, I give up. I've been all over the web, searching images, univ agriculture pages, commercial sites, etc. trying to identify a vicious weed I'm fighting with hours every week.
I have found one guy who posted a pic, but nobody answered him:
This is the *only* pic I've found. What is this weed?
-thin, small, narrow, somewhat curly leaves
-very small yellow and white flowers
-prostrate -- grows in tufts or mat forming
-easily dominates Bermuda grass -- just kicks its ass
-loves heat (sun or shade)
-NOT spurge or knotweed, please study the pic carefully
Location / Yard
In 7 years, I've never seen this before. It's as if an invasive species was brought into our neighborhood on an as-yet-unknown vector. Two of my neighbors have been completely overrun -- they have little grass left. I'm barely holding my own by digging this thing out every weekend.
I would normally never use chemicals -- but in this case, I need to know what the dang thing is and what I can use on it. Otherwise it's just a matter of time until more neighbors get overrun, seeds are blowing everywhere, and I can no longer keep up.
Thanks everyone in advance for your advice.
