herbicide test

I dug up some clumps of winter annual weeds and moved clumps indoors in cups in potting soil and allowed two weeks for growth to resume. I then sprayed them with one of five herbicides and kept an untreated control. Best control was produced by Speedzone and T-Zone which were very similar, next was Quicksilver, next were a 3-way and Drive which were almost equal. Untreated control looked healthy. Photo at 4 days after treatment.

Mysterious, this was an area infested with chickweed last year, and I thought this was young chickweed. Now I am thinking it is not chickweed--the leaves are really small. Does anyone know what kind of weed it is?
