Black rot (also known as black rot, Phyllosticta ampelicida, dry rot, Viala & Ravaz) is a fungal disease of grapevines that is widespread throughout the world. However, due to the similarity in name, it should not be confused with the grapevine diseases black foot disease, black spot disease or black wood disease. It was first described at the end of the 18th century by the French botanist André Michaux (1746-1802). It originated in North America, where in 1848 it brought viticulture in the US state of Ohio to an almost complete standstill, at least in the south.

The glossary is a monumental achievement and one of the most important contributions to wine knowledge. Of all the encyclopaedias I use on the subject of wine, it is by far the most important. That was the case ten years ago and it hasn't changed since.
