Calculate the 77 days to harvest date for each of your cultivars and make the final application of EBDC fungicide (Dithane M-45, Manzate 200, Penncozeb, Polyram, Roper) on that date to take full advantage of the excellent control these fungicides provide for bitter rot, black rot, and white rot, in addition to sooty blotch and flyspeck. This recommendation applies only to growers who used the low rate of mancozeb – 3 lbs/acre. https://ag.purdue.edu/department/hla/extension/sfg-sprayguide.html
