It's affecting my nectarine tree. At first I thought it was "bacterial leaf spot" but it quickly spread to the rest of the leaves and now affecting almost all of the tree. And what's the cure?

Bacteria can spread quickly. Then the disease becomes a bacterial blight.

Should I apply treatment right away, or should I wait until fall? I've seen different opinions on this from different people.

Now, you don't want it to spread or hibernate and then infect others. Like Barney says, "nip nit, nip it in the bud...

If you live in Oregon, this time of year, I wouldn't worry about it. Weather is too dry for further spread.
Best Control is bordeaux/Kocide applied in October, Dec, Jan, and then sulfur at peanut size. I also like Ziram replacing the Dec's Kocide spray. Your choice of fungicide at bud break, popcorn, pedal fall.

That looks like peach leafcurl to me. It's infectious. Treat with copper while the plant is dormant. Dont use clippers or other tools on the next tree without disinfecting them. Keep dropped leaves picked up.

Now all of my fruit trees have it (though not as severely as this one).

Looks like even spraying them won't stop or reverse the disease but will only possibly slow down the progress of it. I hope this isn't one of those diseases that stay for 10+ years and never go away.
