When to irrigate after applying Fame SC Fungicide depends on the target disease per the product label. Some you would irrigate right after application, otherwise you can generally water after 24 hours.
Fame SC Fungicide just contains a different active ingredient but is in the same fungicide group as Azoxystrobin so they work comparably. Either of these should be rotated with a fungicide from a different group after applying 2-3 times to prevent resistance buildup, such as Clearys 3336F or Eagle 20EW.
