Is Tupersan WP in 4lb paper bag 10 years old still effective?

I have 11 bags-It has been stored in the original cardboard box and kept very dry. Would it still be effective? What is the shelf life?

Answer:

Tupersan 50 WP normally last up to 5 years if stored in a cool dry area. Please contact PBI Gordon 800-821-7925 to make sure that your product is effective or not.
