The family and I were at my mother in law's this weekend.  My MIL found a container of Accent herbicide while cleaning and asked if I wanted it.  I said sure, but upon further inspection I found it was formulated in June of 1990.  It was probably left over from when my FIL farmed full time and he kept it around "just in case".

Question - Would this product still be good?  It's been in the container, and while the seal is broken, it probably hasn't been opened until I did this morning.  Probably around 8 ounces out of the full 10 still left in it.  I wouldn't use it until next spring at the earliest, making in 20 years old then.
