Just wondered if powdery or downy mildew from my pumpkins could get on my collection of evergreens?

The fungal spores that cause powdery mildew are everywhere in the air. I don't think planting pumpkins will make it any worse, if your plants are prone to powdery mildew, they will get it when the conditions are right.

It's up to you if you want to treat for it or not. Most evergreens in my location seem to avoid problems with it. I commonly see powdery on deciduous trees like lilacs and dogwoods.

Powdery mildew is a bigger problem when you have high humidity and low wind speeds. That is why it gets bad in August in Iowa. August has our calmest winds of the year, and the corn crop is pumping massive amounts of water into the air. If your evergreens aren't getting mildew now, pumpkins shouldn't cause any more of a problem. But if your evergreens grow up enough to limit air circulation, then you could see it become a problem.
