I bought some last year; worked great. Stored it In a sealed container in the garage over the winter. Went to use it this Spring on my Apple trees and it's hard and caked up. Is it still good to use? I've been crushing it up and mixing it, but have no idea it it's still effective.
This can happen to the Agri-Mycin 17 over time. If it was stored in a sealed container and was not exposed to moisture, it should still be fine to use.
