I have been getting mixed results with Momentum this year. Some lawns it works just fine, even blowing away violets in one app. Other lawns, not so good. I don't have an explanation for the variance but I can tell its there. And to pre-emptively answer some obvious questions, tank agitation is working and adequate. Mixing is reliable and consistent at 1.1oz for .5 gallon to be applied on 1000 sq/ft. Product does not linger in tank for more then a few days, and the applications are being performed evenly and at stated rates.
