    Pennywort keep trying to be a problem in one of the my St. Augustine yards. Image does a fair job on it but take repeated (3) applications to begin to knock it down. It comes back just when I think it's gone. I'm a little afraid to use of the Atrazine and basagran mix in the heat. BTW (2.5 gal 40% Atrazine) has gotten dirt cheap. Back to pennywort: Any suggestions--remember in warm season turf. Area is only about 4' X 6" and thin, but won't go away.
    Suggestions would be appreciated. Thanks, Roy

    well there is no reason to mix basagran in atrazine to kill dollarweed atrazine will do fine on its own...however you run a very high risk of introducing grey leaf spot by using it. nothing else available really other than image and that SUCKS
    for dollarweed.

    When I use manor/blade on dollarweed, its usually back within a few months. I have had better luck with Certainty (1.25 oz/a) for long term control. If it's not too hot, you can mix in a little Trimec Southern to speed up control.
