Hello, have an older ( 2013) sealed bottle of Blindside Herbicide, don't see an expiration date or use by date, does active ingredient go bad or lose potency over time? Even if bottle is open as well?
The date on the bottle of Blindside Herbicide is the date the product was manufactured. The shelf life of most products is 3-5 years once opened. It is possible that products could lose their effectiveness depending on how it has been stored.
