I have been training neptune seedless grapes in espalier fashion. The vines are 3 years old and i just noticed brown spots on the leaves. What is the cause of these spots. I don't see any insects of such on the leaves just the spots. Curious as to what has caused this. Thanks for any help you can give.

That type of damage is usually a fungus, but I have no idea which, or whether it is a real threat to your vines.
