Apoplexy

Apoplexy (GB)

Term (Greek apoplex = stroke, med. stroke) for sudden events with loss of consciousness or partial paralysis. In viticulture, it is also used to describe the poor condition of a vineyard with the complete death of vines. The diseased vines gradually stop growing, the necrotised leaves turn yellow and wither, and productivity comes to a partial and then complete standstill. Apoplexy is sometimes also referred to as an acute form of the wood disease Esca.

Apoplexie - Nekrosen durch Esca (Blatt), Schwarzfuß-Krankheit (Wurzel), Pierce Disease (Blatt) und Eutypiose (Holz)

Strictly speaking, however, this condition is not a specific disease, but the final symptom or extreme effect of various vine diseases. The causes are, for example, water stress (lack of water), extreme lack of nutrients, frost damage, fungal diseases such as esca, eutypiosis or other various wood diseases such as rugose wood complex. In wine, this can manifest itself as UTA (atypical ageing tone). See also a complete list of all diseases and pests in the vineyard under vine enemies.
