Does Glyphosate Go Bad?

mercredi 23 mai 2018

I had about 1/2 of 2.5 gallon container of glyphosate leftover from last year. I mixed up a batch to spray the driveway at 2 oz in 3 gallons of water. It seemed like it had no effect whatsoever!

I checked the container and it had a mold around the top at the cap and some in the glphosate itself. I've never seen this before.
