Can you let me know if this is mold on our pumpkin leaf? Or something else?

This looks like a common fungal disease called powdery mildew. It appears on Michigan vine crops like pumpkins every year. It will eventually kill the leaves. It does not infect the pumpkins themselves, but it can damage their stems.
