Ortho Total Kill What Is The Difference Between Ortho Total Clear And Ortho Ground Clear?

What is the difference between Ortho Total Clear and Ortho Ground Clear? - ortho total kill

Both say they are more or less the same, but different ingredients. Moreover, a clear rationale, is about $ 5 more. I need something cheap, killing everything and avoid the life a little more for a while. Any help most appreciated.
