Copper is bout the only thing I’ve found that will some what control and slow it downI have had it 3 out of 5 years. 2 years ago we had a drought all summer and no septoria. I live in the woods and it is everywhere, no avoiding it. I have not found any treatments that do more than slow it down for a minute, and then, when your plant gets old and week at harvest time, it attacks the sugar leaves and forces you to harvest early. Hopefully the strain that was resistant last year will fair as well this year.
