The battle against Septoria is already waging here since last week. Started with Actinovate, applied copper soap a couple days ago to 80% of the tomato plants before the rains came. Got to do some pruning of infected branches today again when it's not raining.
Daconil would be useless here, it's been raining regularly.
Excel LG doesn't work on Septoria.
Need to brew some compost tea,
Going to try Potassium Bicarbonate in the spray rotation this year.

Early Blight hasn't been a problem, saw one infected leaf a few weeks ago.
If you inoculate your seedlings with mycorrhizal fungi, Early Blight won't be a big problem.
