By no means a cure, I use a rotation of Actinovate and Liquid Copper fungicide(usually Southern Ag), as per recommendation from Johnny's for some control over our usual suspects.
The Actinovate is also great early season before pressures mount. We dip entire flats of transplants into a combination of Surround (mostly Kaolin Clay) and Actinovate before they are planted into the field. This has made a huge difference for us since we started this practice.
Every year is different, but we always have to deal with early blight and septoria. The alternation of bio and chem seems to do as well as anything I have tried other than a shadehouse, which greatly reduced foliar issues.
Best of luck and learning!
