In the eastern vineyards this disease is estimated to infect 30% of grapes while in California it can infect up to half. [83] This can reduce yields by 40–60%. [ 15 ] [ 84 ] Much like black rot, bunch rot overwinters in the berries and infects the next season's crop through spore ejections in the summer. [ 85 ]

[3] In fact, "Viable lesions capable of producing conidia can persist in wood for at least 2 years."
