This disease (also known as Eutypa lata, hardwood rot, dead-arm disease, dead-arm disease) causes death symptoms in numerous fruit species and other woody plants. It has been known for a long time in aprokoses, but was first observed in Australia in the early 1970s, also in vines. It is widespread throughout the world, with older vines in particular being attacked. It is particularly common in Mediterranean climates (Australia, California, Southern France, South Africa). The infection usually occurs after rain on freshly cut vine wounds, where dead wood zones develop. During the course of the disease, dark brown, very hard wooden bodies appear in the wood, which are sharply differentiated from healthy wood. The first symptoms are similar to those that occur when there is a lack of nutrients (such as chlorosis).
