 While the fungus "Eutypa lata" is present in the Hunter, research in the 2000s indicated that another pathogenic species related to "Botryosphaeria" is also present in the area.Semillon vines, in particular seem to be susceptible to "Botryosphaeria" (also known as bot canker) while, conversely, Eutypa dieback is rarely observed in the variety.Vines suffering from Eutypa die-back and bot canker exhibit similar wood symptoms and similarly experiences reduce growth and yields.
