Corrrect. !!!!!

Never ever mix anything with Daconil,I just wrote a long post about this a couple of weeks ago.

The attachment sites for both EB and Septoria are on the upper leaf surface, what Daconil does is to block those sites. If you dilute anything else with Daconil it reduces the number of chlorothalonil molecules so they can't block all the sites.

I'd do a search for my post,it's longer,but I don't have the time.
