EPPO Reporting Service (2014/102) : first found on root samples collected during 1995-98 from slowly declining Ulmus chenmoui trees at San Rossore (Pisa, Toscana region). The nematode was first described as a new species Meloidogyne ulmi which was later synonymized with M. mali. These elm trees had previously been imported from the Netherlands as 3 year old plants. Subsequently, populations of the same nematode species were found at Mantignano (Firenze, Toscana region) on U. chenmoui and U. glabra plants imported from the Netherlands and used as rootstocks of Ulmus hybrid selections.
