Does Glyphosate concentrate lose its efficacy over time?

I have a bottle of Tumbleweed which I applied (diluted as per) 10 days
ago to greenery and nothing has happened. Should I re-apply the same or
rush out to buy anew?

On what? Some things are very resistant, and 10 days is not a long
time in cold weather. Undiluted glyphosate keeps for a long time.

Not unusual to take 10 days to respond. I've just bee through the same
process. 10 days of dry weather - no sign of any affect, a few days of mixed
sun and rain and lots of lovely dead foliage!

A variety, from rhus typhina regrowth to annual weeds (thought I'd just
treat them all the same).

and 10 days is not a long
time in cold weather.

Ok, though it's not been that cold here - I'm just impatient.

Undiluted glyphosate keeps for a long time.

ta both.

It takes a while for it to act, and some plants don't show any signs for
a couple of weeks. I've used Roundup which was ten years old and noticed
no diminution of effect.

If what you are spraying isslightly oily, a touch of washing-up liquid
is beneficial (but not to the greenery!) but don't tell the EC Police...
