Exel LG, Actinovate, Mycorrhizal fungi etc

[BigdaddyJ]

I am an organic grower and I'll be using Pro Mix Biofungicide with Bacillus subtilis in it to start my plants. I am interested in learning a little about Exel LG, Actinovate and Mycorrhizal fungi in order to cut down on mostly Early Blight and Septoria spots and specs I get pretty regularly here in my zone 7 Delaware. I have never used any organic treatments besides the Cornell Mixture before nor have I used this biofungicide potting mix before. I would be interested in what other organic growers use and in what amounts and rotations work well and which of these products could interact negatively with each other or be redundant. TIA
