Blackwood disease

This vine disease (French: bois noir) belongs to the group of yellowing diseases. However, it should not be confused with the vine diseases black rot, black spot or black foot. In terms of symptoms and effects, there are similarities with the vine disease flavescence dorée (with similar pathogens).

Causes

Young vines in warm wine-growing regions are particularly susceptible. The pathogens are phytoplasmas (bacteria-like microorganisms) of the Stolbur type (hence Stolbur disease), which are transmitted by cicada species. The main vector is the glass-winged cicada Hyalesthes obsoletus. They only appear in vineyards by chance, which is why the disease only spreads slowly and to a limited extent.
