Grass burs! Help

[Wilburn Cox]

I have 4 acres here in Stephenville TX and about 2 acres are covered in grass burs. I put out pre-emergent granules in early spring and thought I would be ok. The rains began, then lots of hail. We had 41 inches of rain in the first 6 months of this year.
Several years ago, living in another location I use a product called MSMA and it worked fine as a post emergent. The product was taken off the market. I ordered 2.5 gallons of Target 6 Plus (concentrate) which is supposed to have MSMA in the mix. I hope this will work as a post emergent.
How do some of you control grass burs? Any help will be appreciated.
Thanks in advance.

I didn't know MSMA had been taken off the market. I still have a quart or so of Image herbicide with MSMA that I've used for crabgrass and clover. And I need to spray some more clover.
