Michael, the action of CuSO4 against the Sigatoka fungi is not terribly well studied - it's been sort of taken as a given that "it works" and left alone. As far as I can tell it messes up something in the cytokine metabolism of the fungal cells, so they die rather than metabolizing properly.

There's a good chance of leaf survival if the necrosis was less than 30% of the total leaf area.
