I am trying to be more proactive this year in controlling diseases on my tomatoes, especially early blight. Last year I use the copper spray, but started too late for optimal effectiveness. After researching previous threads on this topic, this year I am using Actinovate as a soil drench and foliar spray, along with Exel LG.

I have decided to alternate with another spray every other week. I am considering both copper and Seranade. I do realize that Daconil is the most effective of my options, but I would like to try organic methods if possible. Has anyone done this type of alternating schedule? What products did you find work best? And does spraying copper have a negative effect on the effaciousness of Actinovate/Exel LG if there is at least a week between sprayings?
