Southern Ag Liquid Copper Fungicide is the same. It is Copper diammonia diacetate complex at 27.15%. A pint will mix 20 to 24 gal. of spray. A pound of copper sulphate will mix about 24 gallons at 1/2%.
As I said above, I can mix copper sulphate much less expensive than buying brand labeled mixture of the same chemicals. Copper suphate is readily available while other copper compounds/chemicals are not.
Do a web search for more info on using copper sulphate on bananas. You will find that the Bordeaux and Burgundy mixtures have been used since the 1920s on bananas.
