There are several diseases that can plague grape vines. As I look at the pictures, I believe that you are dealing with Phomopsis Cane and Leaf Spot. You can find more information about this grape disease as well as possible chemical control measures at https://winegrapes.tamu.edu/grow/phomopsis.html.
Thank you very much, Richard, really appreciate your response!
I am looking for organic control if it is possible. What is your suggestion?
It keeps raining these days that doesn't help! :(

Sulfur or copper based products might give you decent control. I do not know if neem oil would be effective or not. When pruning, remove the infected canes and destroy by burning.
Thank you Richard!
I am ordering those products.
