Controlling powdery mildew on cucumbers

My cucumbers have powdery mildew on them. I looked at the instructions on my bottle of Safer brand mildewcide. It said not to use it when temperatures are expected to exceed 85 degrees F. It has been getting up to around 100 lately.
Is there something else I could use? I have read about using powdered milk. Does it work well? Is it safe at high temperatures? How much should I use in 0.5 gallons of water? Thank you in advance for all replies. -- Whenever I hear or think of the song "Great green gobs of greasy grimey gopher guts" I imagine my cat saying; "That sounds REALLY, REALLY good. I'll have some of that!"

g'day daniel,
lots use milk mostly from the bottel see our remedies page i think the recipe is there.
we also find planting susseptable plants in well drained medium and well ventilated area ie.,. breezy spot keeps pm away until the plant has all but run its course, and that is to be expected as the plant is not as strong then.

once again daniel,
i forgot to mention when watering try to avoid wetting the foliage and water in the mornings so there is time for any that does get on the foliage to dry off before evening begins.
