This is the main weed taking over

If you just have a spot of it, I would round up it even though you kill the grass in that spot you can get the grass to grow in a short period of time because Roundup doesn’t stick around very long.

Interesting.  I had some of that crap show up at my place also but didn't know what it was called.  I like Virginia Tech's name for it....Stickywilly.

As others have said Grazon or Crossbow get it.  Both are much more effective pasture sprays than just 24-D alone.

Good luck.

Thank you all for identifying this SOB and offering options.

Says I need to control the weed's seed rain prior to application.

Huh?

I'm not sure where you read that.  But I assume what they are saying is that if it's already gone to seed you will have more come back after you kill it with a post emerge chemical like Grazon or Crossbow?  Just a guess, I'd need to read what you are referring to.

Yes, basically just saying that Crossbow is not a pre-emergent herbicide so if you allow it to go to seed those seed will still be viable and come back.  So you either spray it before it goes to seed or you may have to spray again after more comes up.

MTO saw bedstraw in BIL hay field.
 

Was told 1.5 pt/a of GrazonNext with surfactant.   Only issue is you have to control where the manure from the horses goes as it will continue to kill broadleaf plant to for up to 2 years.   Manure can only be used on grass hay, wheat, oats or corn. No garden use.

Forefront is GOOD stuff. But I thought they quit making it about 5 years ago.

I had a neighbor that must have thought Canadian thistles were pretty so I ended up with a patch in my pasture. Pasture -Pro or similar would burn them down, but didn't kill them. Forefront inspring when they were greening up, and then summer when the second crop was coming on. Poof no more Canadian thistles.      

Chemical guy said it will also work as a lawn spray but you don't want to mix it very strong.

Forefront was aminopyralid + 2,4-D. They dropped Forefront and went with GrazonNext, which amazingly enough is aminopyralid + 2,4-D. Graslan is picloram + 2,4-D, which is the old GrazonNext P+D. They did use the new choline 2,4-D formulation in the Graslan which greatly improves volatility and drift. Again, I would recommend Graslan or GrazonNext at 2.0 pints/ac plus NIS at 1 qt/100 gals. It won’t be a one year and done deal- soil seed bank will be an issue.

We have that weed in areas that are not intensity farmed. It really takes off when fertilized and I wonder if the horse dung is making it worse . I think lime being correct level is a deterrent to it unless it's just because better plants grow better then

I put 8 oz of GrazonNext with 8 oz surfactant in 15 gal sprayer which covers 1/2 acre.

Next night I used 10oz and 10oz and did next section to see if much difference is obvious. 

I got 2ish gallon jug of GrazonNext at $60/gallon.

I think you will see it in horse poo, some of these hay jockeys will cut everything they can for “mulch hay” but they’ll sell it to horse people in a heartbeat if given the opportunity
