CULT: Fungal Leaf Spot

We've got the worst hail damage I've ever seen on our irises this year. Some
plants look like they've been shredded by cockatoos. But all plants,
especially the bearded irises are completely covered in white hail damage
spots.

In my experience the hail breaks the waxy coating on the iris leaves and makes
them far more prone to fungal leaf spot. We normally get a bit but have never
sprayed for it.
However this year it is the Aust Iris Convention here and we'd like our
gardens looking extra good, not hugely worse than ever.

For those of you who do spray for funal leaf spot, what fungicide do you use
and what additives do you add the help it stick?

Many Thanks
