Joseph's Coat Rose & Black Spot

I have two beautiful Joseph's Coat roses.The blooms are incredible, but after early spring, it's a constant battle with black spot in our very warm & humid climate.But they survive & come back to bloom again.
I've tried spraying sulpur (not great results) & am getting ready to try a liquid copper spray. I prefer not to use stronger, chemical stuff. I pick up all the diseased leaves & discard, use mulch, etc.Any other suggestions?
Thanks so much!
