Sorry, tell me if I understood, I have to spray dithiocarbamate every month a or a dithiocarbamate plus a stribilurin every month, is it right?
If I'll spray both of them I have to spray them together in the same treatment or separately by few days?
Or I didn't undertood and you mean to spray a month a stribilurin and the next a dithiocarbamate?
Unfortunately there is no pistachio growers here, only grape, olive tree and other fruits growers, so I think none could help me here! :(

I noticed some spots also on my cercis siliquastrum which were near my terebinths during autumn and winter!
Is it possible that septoria of my terebinths infected also my cercis?

Good morning!
After a few days of rain I noticed that these spots have appeared on my pistachios from seed .
I took away the leaves with spots and I gave a treatment with penconaole at 0.2% and I will give another one next week.
My terebinths, near these plants semms to have no syntom but I treated them too.
According to you is it septoria, again, or something else?
