    I checked several university sites & other weed ID sites on the net. Can't seem to pin these down. Any help would be appreciated!

    Either way, Momentum FX2 should handle these, no?

    The pictures of corn speedwell on the websites seem to be different than the top one.

    Thanks for the ID on the second one. Again, the website's pictures vary and I finally found a pic like mine by googling the name you provided.

    THANKS, BIG TIME!

    Top weed is not speedwell. Looks similar to greenbriar, but I don't think it is.

    Need more info. Any thorns? Is it woody? Is it a vine? Sun or shade?

    Top weed is not thorny, not woody, nor a vine. In sun & shade both...appears to be a lighter green in grass.
    Pictures are close-ups. They are both around 4-5 inches long.

    Top weed is Veronica filiformis, or speedwell. In a few days it will have tiny blue flowers. Very difficult to kill. It is a winter annual. Arises in October. blooms and seeds in spring. Dies when temps hit about 85 for a few days. Drive is labeled for control.

    Top weed is not speedwell.
    See:
    www.msuturfweeds.net
    The site shows pics of all the different speedwells, and the top weed looks nothing like corn speedweel or creeping speedwell (verinica filiformis)
    Speedwell has already bloomed in central Iowa, so I figure the same for Missouri.

    I don't know what it is. Wish I did.
