Ditylenchus radicicola (Greeff, 1872) Filipjev, 1936, een wortelaaltje in het Nederlandse grasland

Summary Ditylenchus radicicola (Greeff, 1872)Filipjev 1936, has been found since 1950 in 75% of the Netherlands' old meadows as a generally distributed parasite on grass roots. Additional data on the morphology of the eelworm are given. Eleven grass varieties were found to be attacked under natural conditions; 7 of them are new host plants. Damage in our meadows was not observed. However this eelworm is considered a noxious parasite of cereals abroad and in view of the economic importance of grassland in our country further information would be desirable.
