Main symptoms



Aureobasidium pullulans , a yeast-like fungus, is sometimes responsible for the spectacular browning of the stalk (Figure 1).

Let us add that burns on leaves and young vine shoots have been attributed to it. It would also be a usual parasite of grape berries, sometimes causing their degradation accompanied by lysis of the skin during storage.
