ok, this is what we do. Shawn Banks will tell you our mix works better for us in the SE than in the midwest because our water is so soft (see there is some advantage to haveing poor water quality)

Mix with a gallon of water:

8 ozs Ktea, Cutrine+, etc. (8% liquid copper)
4 ozs Reward
1 ozs surfactant

It will require couple of treatments.

This what come with expereiecne and the problem with blanket statement on how to mix BUT

we give a good mist on the pihtophora, you can see it at this rate lightly turn the alage blue. You do not have to hit it too hard but also if you spary one area and miss another it is not giong to kill missed area. You expect to miss some thus the reason for mutiple applicaitosn. THis combo wil safe quite a bit of money vs. Reward alone. Hope this helps.
