Shelf Life
OT, but what's the consensus of herbacides, Pre-M, etc. I really ought to check if my stuff has best use dates. I'm the type that does believe when buying things to look at batch code dates, deciphering if batch codes like 020034899 is a batch code date, or if the manuf. uses something cryptic that they can only decipher. I always look for batch code dates, just to make sure product is fresh. Which got me thinking about the shelf life of the products I use on the lawn....which I've never actually put much thought into, aside from the fact that I keep 75% indoors, just because it's -cooler and more ambient temp controlled- than my garage

Re: Shelf Life
I try to only mix enough spray product liquid for what I need per application and not store any mixed content. I have resealed concentrate liquids that I bought about two years that still seem to be effective. Not storing for two more than years is a vendor recommendation in the below document:
