Does Roundup lose potency after time?
I have a 2.5 Gallon jug of Roundup concentrate that I forgot about. I had used about 1/2 gallon from the jug 4 or 5 years ago.
Last week I mixed up a sprayer with double the strength recommended and sprayed some fence rows.
Today, I went to check how it worked....it just seems to have enhanced growth and hasn't killed the weeds.
I know how Roundup works and a burst in growth can be expected but....after a week of dry conditions, I expected to see some wilting.
Nothing.
What are your experiences????
I'll buy some new jugs in the morning.
