What is bortritis?

Answer 1

I think you mean botrytis (Full name botrytis cinerea).
This affects grape vines and is known as "Noble rot" as it
produces wines of intense sweetness and flavour.
Mainly sauternes and barsac.

Answer 2

Botrytis cinerea is a fungus that affects many plant species, although its most notable hosts may be wine grapes. In viticulture, it is commonly known as botrytis bunch rot; in horticulture, it is usually called grey mould or gray mold. The fungus gives rise to two different kinds of infections on grapes. The first, grey rot, is the result of consistently wet or humid conditions, and typically results in the loss of the affected bunches. The second, noble rot, occurs when drier conditions follow wetter, and can result in distinctive sweet dessert wines, such as Sauternes or the Aszú of Tokaj. The species name Botrytis cinerea is derived from the Latin for "grapes like ashes"; although poetic, the "grapes" disappointingly refers to the bunching of the fungal spores on their conidiophores, and "ashes" just refers to the greyish colour of the spores en masse. The fungus is usually referred to by its anamorph (asexual form) name, because the sexual phase is rarely observed. The teleomorph (sexual form) is an ascomycete, Botryotinia fuckeliana.

Answer 3

Bortrytis is a group of fungi that effect plant s of the family Bortrytinia. Vineyards are especially effected in wet cool springs, causing shriveling of the grapes.
There are also references to botrytis.

Answer 4

A saprophytic fungus, that can turn parasitic in cases of extreme infection. It can affect any dead plant tissue - most commercial nurseries must take strong hygiene controls to prevent spread. Not restricted to grapes!
