Apple rust leaf

I am looking for someone to confirm that what I have is apple rust leaf?
I got this Cortland in the fall but the leaves had already fallen. It also did not flower in the spring yet the pear tree I got at the same time did. I should mention that I do not see any fungal tubes stick on the underside of the leaf and not a small portion of the leaves have the spotting.

Thanks,
Kris

It looks like I was correct that my Cortland apple tree has cedar rust. Here are a few pictures from today.

I suspect it came from the nursery when I got the tree in early spring 2013 or from the wood chip pill I got delivered in the fall of 2012.

oh yeah, you have cedar rust - it will get on the leaves and apple skin, but not the meat of the apple. It also looks like you may have powdery mildew - I'm surrounded with cedars and rust is unavoidable, but you have a bigger problem with the mildew. You should call the nursery asap. YUCK!

I don't believe I have any mildew. The picture was taken in full sun and it got a little over exposed as a result.

I will know more next year.

I would surely take a cutting and go to the nursery. I have a nursery and it's our job to help, advise and make right anything that comes off our lot - hopefully they will advise and fix. As far as the cedar rust - if there are cedars within 5 miles, they may be the culprits. If it's bad, pluck the effected leaves and bag them, don't compost or burn. You can polish the rust off the apple skin.
