Mildew on vine leaf
For a wine tourist, it is essential to recognize this disease.
On mature leaves it flourished between the secondary veins, which draws geometric shapes, then it is given the name of mildew mosaic.
When the white dust appears on the lower leaf surface (oil stain on the top), it's been several days that mildew grows in the leaf. The white dust appears in a few hours in the morning.
