Don't know:-) You could do two separate sprays or maybe ask in TFF

Bit cold for glyphosate although my lawn looks fairly healthy.

Difficult to say. BA is a base, and glyphosate an acid. They are
supplied as salts - BA as the chloride, and glyphosate as an
isopropylammonium or trimethylsulfonium (ie both similar to
benzalkonium) or sodium salt.

They might exist in solution together; they might not. The only
incompatibilities for glyphosate here:
<http://www.apparentag.com.au/documents/data/apparent-compatability-chart.pdf>

are diquat and paraquat (both bases)!

Or the fact that they never actually stopped growing in the first place,
same goes for moss.
Bah humbug.

IME, glyphosate works on moss too, so you could use just that.

There are separate moss killers too, for where you don't want to destroy
other vegitation, but when you do, might as well just use glyphosate.

Or use something like Pathclear, which is glyphosate to kill what's
there, plus a germination inhibitor to prevent new growth.
