    Air flow, this is key, if you can reduce humidity, I am trying peroxide and water, 1 T H2O2 to 1 cup H2O, Trifecta Crop Control works but costly, remove badly infected areas.
    More details helps. Are they inside or outside?

      Yes what Rwise said to do. Air flow and keeping branches from touching in high humidity.
