Q.How do I fix brown spots on my grapes and leaves
I live in Conroe, Texas where I have a little bench trellis that I decided to experiment with growing grapes on. Some of the grapes and leaves have brown spots on the immature grapes and leaves. The grape plants that are much younger that are still on the ground level are perfect though.
Are the brown spots a fungus? Are they caused be a disease to just one of the larger plants? Perhaps caused by a bug/insect? What can I do to fix it? Help!!!!

This actually could be environmental, to much sun or wind can cause this.
Inspect the leaves closer and use the links below to either match or eliminate the fungus or bacterial disease.
