Until the beginning of the 20th century, the cause of this Rebstock disease, also known as Rotbrenner, was unknown; nutritional deficiencies were suspected. In 1903, the Swiss discovered Hermann Müller-Thurgau (1850-1927) as the pathogen the parasitic mushroom Pseudopezicula tracheiphila, after which the disease is sometimes named. The fungus hibernates on withered leaves on the ground, this is also the main infection focus. The disease mostly occurs in shallow, stony and dry slopes after prolonged rains, the spores thrown out from April to July shoots and leaves,

The symptoms are yellow-brown (in the case of white wines) or ruby-red (in the case of red wines) spots which are delimited by the leaf veins and therefore appear angular. The discolored area is surrounded by a light green to yellow border. The leaf veins are blocked and thus the photosynthesis prevented. Later on the discolored spots form necrosis and the leaves wither. In very dry and hot weather, the discoloration does not occur, the leaves dry out very quickly and fall off. Occasionally, fishes are also attacked, which is shown by small black dots on the flowers. In this case, after the blossom also Verrieseln occur. The fungus becomes protective in the vineyard fungicides already combated preventively. The Pinot Noir variety is particularly at risk ( Pinot Noir ). See also under Vine enemies,
