Quikscan - Meloidogyne mali


This Quickscan concerns the root-knot nematode species Meloidogyne mali. M. mali is a polyphagous Asian nematode species parasitizing on several trees, shrubs and herbaceous species. It is a damaging nematode species able to induce large root galls resulting in a malformed root system with retarded growth and possibly influencing the stability of the trees. It is especially considered a risk for tree species because of the high costs for replacement and because infested trees may be more vulnerable for heavy winds. M. mali has probably been introduced into the Netherlands from Japan with elm root stock. It is known to be locally present in Baarn, Wageningen and The Hague mainly on elm trees.
