What is the shelf life on fungicides that have been opened but are kept in their original container? I ask because I have some daconil that was opened last year and was kept at room temp since. I don't want to be spraying something that doesn't work. Thanks!

Flowable fungicides like Daconil last for years as long as they don't freeze. I've been working out of the same bottle for 3 years already.

Emulsifiable Concentrates like Banner last longer since they are less likely to freeze.

Wettable Powders last the longest since they can't freeze at all. I have some Mancozeb WDG that was formulated in 1996 that is as good as new.

When stored properly, none of these formulations are going to "go bad".

Toss in a couple, of small stones, nuts or marbles and shake the Bejesus out of them. Most will come back with a little effort.
