If there is a weed that has defied every herbicide I know, it's this.

Please recommend if you know any herbicide that can kill it.

Actually, I have not seen any. I didn't have to open the thread before I knew that it was that weed you were talking about. Try uprooting them before they produce those flowers (they airy flowery seeds can travel fast and have a very high rate of germination -- in short, they can frustrate you). The more you uproot them before they produce flowers and mature, the more you see them disappear.
