I am wondering if I am dealing with a case of powdery mildew that has become resistant to class 3 fungicides

in the triazole family. Will using Azoxy 50 a class 11 fungicide with a different mode of action work on the powdery mildew that has already become resistant to class 3 fungicides?

Yes, you can use Select Source Azoxy 50 WDG Fungicide to help treat the powdery mildew. We recommend switching classes every two sprays. For example use the one you are currently using for two sprays and then use Select Source Azoxy 50 WDG Fungicide.
