ABSTRACT The root-knot nematodes Meloidogyne chitwoodi and M. fallax are listed as quarantine organisms in the EU. European legislation aims to prevent their spread. In Belgium, M. chitwoodi and M. fallax are present in areas with potato and vegetable production. The infested area is confined to certain regions and avoiding further spread is of paramount importance. Only second-stage juveniles (J2) and males move freely in the soil but these movements are limited. Passive dispersal through soil, (waste)water and plant material is more important. To assess the risk of spread through waste products a survey was conducted to determine if quarantine nematodes are present in waste products of the potato and vegetable processing industry. From our results it is clear that soil adhering to plant products poses a threat and should be subjected to phytosanitary measures. Also, survival of M. chitwoodi, M. fallax and M. minor in (waste)water and soil was assessed. The effect of treatments such as drying, heat, inundation, sonication and UV on J2 and intact egg masses was examined. Eggs inside intact egg masses were better protected than loose eggs or J2, resulting in higher survival rates. Cost-effective treatments are available and, together with increased awareness, can avoid further spread of quarantine nematodes.
