Extensive group of microorganisms (lat.Fungi) with around 100,000 species. After having been assigned to the plant kingdom for a long time, today they are considered a separate kingdom due to their physiological and genetic properties and are more closely related to animals than plants. In contrast to almost all plants, you can without chlorophyll exist and feed just like animals from organic nutrients in their environment. Mushrooms therefore do not develop photosynthesis (and therefore do not need any light), but as putrid residents, parasites or live as symbionts of dead or living organic substances. They often enter into a mutually beneficial symbiosis with the host plants. Also for them fermentation important yeasts are mushrooms. A large group is under molds summarized. The growth of many mushroom species is due to high relative humidity from about 70%.
At the Rebstock Different types of fungi can cause the pathogens of numerous diseases anthracnose. Botrytis (Noble rot, gray rot), Esca. eutypa dieback. green rot, real and false mildew. Petri's disease Pink rot Red burner. black rot. Black spots disease (Excoriose) Blackfoot disease. white rot and Welke his. They are mostly different fungicides fought. Many grape varieties must be within one growth cycle (Yearly) treated five to ten times. However, certain types of mushrooms are due to the decomposition of decomposing substances in the soil and better supply of the vine nutrients in symbiotic coexistence with the host plant also vital for its flourishing (see under mycorrhizal ). In the breeding new grape varieties, it is now an important breeding goal that a high resistance against different types of mushrooms. Such varieties are particularly popular Organic (ecological) viticulture asked and are considered PIWI varieties (fungus resistant). See also under Vine enemies,
