Already using copper - Add Actinovate or Exel LG?

[elixir]

First, my plants seem healthy right now. But this is my first time growing tomatoes and I don't want to lose the crop that's nearing maturity. I picked up copper earlier in the season to treat mildew.

Since I'm already using copper sulfate as a foliar spray, I'd rather not buy two more products. Between Actinovate or Exel LG, which would be more beneficial to add as a preventative measure?
