Headway G is a mixture of a Group 3 (propiconazole) and a Group 11 (azoxystrobin) fungicide. Headway G has two modes of action to help prevent resistance however incorporating a 3rd fungicide of a different group fungicide can be effective depending on the specific disease you are targeting.
Please refer to the product label for any additonal recommendations for adding another fungicide to the rotation program and our helpful Beginner's Guide to Fungicides for more information and details.
