Abstract : In 1987, a shipment of nursery mango trees was found to have symptoms of crown and root rot before being planted in the field. P. palmivora was isolated from decayed rootlets and from the potting mix of affected plants. Inoculation studies showed that this fungus was highly virulent to mango seedlings but not to rough lemons, oranges or chilli pepper seedlings. This is the first report of P. palmivora on mango in the continental USA.
