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?


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!
