Natural/organic prevention of early blight? - Page 2

According the the University of Minnesota Extension, early blight is "common" in Minnesota.
I haven't ever sent affected leaves into a lab, but I suspect it's early blight that I usually get.
Thanks for the additional suggestions!

Here in Chicago, EB started about couple of weeks ago. We will get PM later in August.
It is also often not a single case- as in only EB or only bacterial, those problems can and will come in packages.
Once tomatoes go into production stage, there is different type of stress they have and this is usually when all the nasties show up. Does not mean they were not there earlier but just plant did not react to it because it was able to cope being protected by good guys/ and lower stress.
