I'm no chemist, but it's best not to mix strange chemicals...reactions & all.

I guess I should clarify. I'm going to mix them together in the sprayer in 2 gallons of water, not directly mix them.

The first two appear to be weak acids, and Tenacity does not appear to be a strong base so I don't imagine they will react strongly with each other, particularly when you are only adding tiny amounts to 2 gallons of cold water. It is interesting that Tenacity is synthesized partly from nitrobenzene. While both chemicals are a yellow/almond colored oily substance, nitrobenzene will kill you real good, while Tenacity seems not to.

I'd guess from a safety standpoint you are probably fine, but whether these things react with each other and reduce effectiveness is another question. I guess you have to try to know for sure. I wouldn't mix them together full strength just on general principal that you don't know exactly what will happen.

I assume no responsibility if you lose your eyebrows!

Nitrobenzene while it can be toxic can be safely handled. We used to routinely use it in an assay for chloride.

I wish people would take a chemistry class to learn about the world we live.

I am in my seventies and have handled many of the metals in the periodic table and have not suffered any bad effect. I have also worked with many organic compounds

This could be interesting.
