Abstract

First report of the root-knot nematode Meloidogyne Mali infecting elm trees in Belgium.

Abstract

In April 2018, root samples of elm trees (Ulmus) were found to be infected with Meloidogyne mali in Belgium. The root samples exhibited irregularities of the root pattern, appearing as a 'string-of-beads', typical of infection by M. mali. The nematodes were identified based on morphological characteristics and sequence analysis of the ITS ribosomal DNA. This is thought to be the first report of M. mali in Belgium.
