Looks like I have powdery mildew on my azaleas. It is likely from irrigation overspray which has been addressed. I read that Propi can be good for powdery mildew on shrubs but I can’t find the rate for a small tank, only 100gal tanks. Should I used the same rate as used for turfgrass 1k sqft?

I mist my peony plants with propi at the 1oz/gallon rate to prevent them from suffering from powdery mildew. I can't imagine that I use more than a few ounces per plant. I then spray the soil and mulch around the plant.
