The label is required by law to tell you the ingredients and proper application, including frequency limitations. This article has links for you to look up information about those chemicals.

What I've heard describes mixed results. Repeated treatments will probably be required, and if the underlying conditions predisposing the area to creeping charlie aren't addressed, it may keep returning.

I did use it last year. I did not take advatage of it's usefulness in colder temps, which may have been a downfall. I tried it on CC and regular lawn weeds and clover. No advantage I've seen over trimec for violets, maybe a bit better for CC but I am not convinced yet. Quicker results for clover, but overall not worth the extra money, IMO. This, being my preliminary results.

I never found a accessable source for the "special ingredient" without dicamba mixed in it already.
