| Abstract:
Worldwide, and mainly in Europe, South Africa and California, young vineyards have experienced unusual fungal diseases which have dramatically shortened their productive life and increased management costs. As a consequence, growers have been forced to replant sizeable vineyard areas, resulting in serious losses and compromising the stable production in viticulture and wine industry. “Young grapevine decline”, “young esca”, “black goo” or “Petri disease” are common names for the decline of young vineyards caused by or associated with Phaeomoniella chlamydospora and species of the genus Phaeoacremonium. Also “brown-wood-streaking” of rooted rootstock cuttings, bench-grafts and mother-plants of rootstocks is caused by these fungi. In Portugal, like in other countries, black foot fungi (Cylindrocarpon spp.) alone or combined mainly with P. chlamydospora, are also responsible for similar syndromes. Decline symptoms expression is deeply influenced by environmental conditions and cultural practices. Based on information and experimental data currently available, the decline of young grapevines is discussed here. | |
