I’m sure this was asked before, but couldn’t find it. Could I mix tenacity/triclopyr with FAS?

I don't see why not. Usually good to mix iron in with your herbicides.

I hope this isn’t off topic as I know the primary use here is for greening. Interesting enough I have a moss/ algae problem and was searching for solutions when I came across this report from UG:

Turns out they recommend FAS as a remedy for both algae and moss(though they didn’t do well specifying amt).

I was about to do a broadcast app of chlorothalonil, but thought it might stress the lawn and technically not suppose to use residentially (though I would plan to treat only my other plants…outside…on the lawn…with my broadcast sprayer…).

This sounds too good to be true, but going to try this before chlorothalonil.

@ken-n-nancy follow up to other thread.

@g-man not sure if this should be on the FAS thread or fungicides.

I'm curious the schedule everyone applies this mix at. I've searched and could only find references to people apply it when the apply PGR or before a holiday. Any other schedules or ideas? Trying to map out next year already, ha!

I apply the FAS for almost every foliar app I do....TNex, fert, herbicide, etc. approximately every two weeks. I definitely have the greenest grass on the block.

@Jagermeister Are you applying at the same rate every time? If so what rate are you applying at? I am still working on dialing my rate in.

@Jagermeister Are you doing no Nitrogen and just FAS? Is that "common" amongst users here?

@Trent161 Yes, applying per MQ's recommended rates for bermuda in the first post of this thread.

@RBall I don't just spray the FAS. I normally combine it when I am spraying herbicides and TNex. I spray TNex with my fert apps every couple of weeks. I have only done a couple broadcast herbicide apps this year - Celsius, quinclorac, certainty, etc.
