Black foot disease is a root and stem disease of grapevines. Due to the similarity in name, it should not be confused with black rot, black spot disease or black wood disease. The disease was first described in France in 1961.
It is caused by the fungal complex of the genera Campylocarpon, Cylindrocarpon, Cylindrocladiella and Ilyonectria, among others. These can occur individually or in combination. Infestation of the plants is promoted by waterlogged, clayey soils and excessively fertilised vines. Younger plants are particularly affected (Fig. 2).

Serious sources on the internet are rare - and Wine lexicon from wein.plus is one such source. When researching for my articles, I regularly consult the wein.plus encyclopaedia. There I get reliable and detailed information.
