Hi Charles –

Serenade Fungicide does not have an expiration date on the label. However, the following was taken from a UC Davis fact sheet titled: Biopesticides: Bacillus products for Disease control

Bacillus subtilis has a good shelf life, generally 2 years room temp for liquids, longer for dry formulations AND very compatible in tank mixes with other agricultural products.

Hope it helps!
