Extensive group of microorganisms (Latin Fungi) with about 100,000 species. After being long attributed to the plant kingdom, they are now regarded as their own kingdom due to their physiological and genetic properties, and are more closely related to animals than plants. In fact, unlike almost all plants, they can be without chlorophyll Like animals, animals live and feed on organic nutrients in their environment. Mushrooms thus do not develop photosynthesis (and therefore need no light), but must as a decaying inhabitant, parasites or live as symbionts of dead or living organic substances. They often enter into a symbiosis that is beneficial to both sides with the host plants. Also for the fermentation important yeasts are among the mushrooms. A big group is going under molds summarized. The growth is high in many species of fungi humidity from about 70% favors.
At the Rebstock Different types of fungi can be the cause of many illnesses such as anthracnose. Botrytis (Noble rot, gray mold), Esca. eutypa dieback. green rot, true and false mildew. Petri's disease, Pink pillar, Red burner. black rot. Black spots disease (Excoriose) Blackfoot disease. white rot and Welke be. They are mostly different fungicides fought. Many grape varieties must be within one growth cycle (Year) treated five to ten times with it. Certain types of fungi, however, are due to the degradation of decaying substances in the soil as well as better supply of the vine nutrients in symbiotic coexistence with the host plant also vital for their prosperity (see under mycorrhizal ). In the breeding new grape varieties today it is an important breeding goal that a high resistance is achieved against different types of fungi. Such varieties are especially in the Organic (organic) viticulture asked and are considered PIWI varieties (fungi-resistant). See also below Vine enemies,
