Can I tank mix ammonium sulfate, humic acid and mesiotrione?

I have some 21-0-0 that is 21% nitrogen and 24% sulfur.

Can I mix this with humic acid and RGS?

Can I also include meso? I have a generic version of Tenacity.

Better not. Tenacity and very low amount of AS will work well together to enhance the herbicide effect. RGS is soil applied.
AS at fertilising rates left on blades may burn your lawn.

I think I was confusing the tank mixing of AS when I was reading that PGR thread.

Any thoughts on how much AS to use to enhance the effects of Tenacity?

W@turfnsurf Go with 2-3oz/gal. Some NIS will further speed things up and increase efficacy.
