So I think it is "Hairy Bittercress" anyone agree?

Yes it is hairy bitter cress indeed and it can be controlled by using post emergent weed killers with 2,4d with triclophyr as active ingredients.

THANKS!

It's an annual and the seeds disperse widely (another common name is shotweed) so a post emergent is not likely to provide complete control. I'd try a pre-emergent as well.

Pull it before it pops! ;-)

First photo of plant growing in place shows seed pods have already formed. Unless you are a magician, it is impossible to remove without dispersing the seeds once it has set seed.

Ask me how I know :-))
