What is wrong with my peach trees?

Can some kind soul look at these pics and offer their opinion as to what is wrong with my Peach trees, and what I can do about it? I planted them winter before last, and last year they grew great. This year they look pretty bad, and they are barely starting to grow:

Peach leaf curl. this batch of leaves will fall off, and another batch will come on later in the year.

Yeah, I see that. They say to spray in the fall or spring before it starts to grow. Is there anything that I can do now, or is it too late?

Just clean up the leaves that fall now, destroy them. Somewhere in my memory it seems like you can spray now, which will kill the leaves that are out, but it's been many years and I can't find my books.

I found a copper based fungicide, but it says to not use once leafs start to grow. I have some calcium polysulfide which can be used in a dilute form once leafs bloom. <sigh>...guess I'll watch and see what happens.

Well, as far as making a sweeping generalization from a random sample, I can tell you I had peach leaf curl (curly leaves anyway) last year on my dwarf peach and, had a bumper crop. Go figure. Maybe I get an exemption for living in the land of fruits and nuts. Given up on figuring-out who is who though.

It is recommended that you give at least one good fungicide spray to control this problem. Cleaning up and discarding the leaves is a good practice, as is aggresively thinning the fruit while the problem persists, since there may not be enough leaves left to sustain the fruit and maintain tree health.

someone on the group said in the past "The only effective treatment of peach leaf curl that I have used in fungicide applied during dormancy. Ferbam after leaf drop or just before buds swell. Severely infested trees both fall and late winter applications are recommended, I also use lime and sulphur and dormant oils for other problems but it did not suffice for peach leaf curl."

That is the information I keep coming across. I wish I could do something about it now - one tree looks so bad, I don't see how it can survive.

Leaf curl.
You can't do anything about it during the growing season this year. When the trees go dormant, you need to give them three applications of dormant spray.

I hope you don't mean 'dormant oil' spray. That would do nothing for Peach Leaf Curl. You need a proper fungicide like Bordeaux mixture to do the job.
