Default Battle with blackspot on Roses.

I am fairly new to Rose gardening and have one hybrid tea rose (Chihuly) right
now. I have the plant in a large plastic pot where it has been for 2 years, here in
the Dallas, TX. area. For two years I have been removing leaves that appear
infected, and spraying the top and bottoms of the leaves with the ortho
commercial fungicide (chlorothanonil). I didnt think it was helping much because
this is a constant battle, having to remove leaves, pick up the dead ones, spray,
etc... every week... I recently decided to try baking powder (I didnt have
baking soda), vegetable oil, and insecticidal soap. Mixed the appropriate levels
of each, and sprayed... Since approximately 1 week, nearly half of the leaves
appeared infected, and most have dropped off. I want to keep the rose, but I
want to try and kill this fungus somehow... ill try anything. I even thought that I
would wait until fall temps dropped and I would pull the plant out of the original
container, remove the soil completely (bare root) and cut back the topgrowth.
Bleach the container, discard the soil, and lightly spray the outside surface of the
rose plant with a 1/10 mixture of bleach or soak the plant, etc.. for a brief
period of time. What can I do? Anything?
