Over de betekenis van vrijlevende wortelaaltjes in land- en tuinbouw with a summary: on the significance of migratory root eelworms in agriculture and horticulture

Oostenbrink presents evidence showing the role of the migratory root eelworms, mostly species of Pratylenchus, Paratylenchus and Hoplolaimus, in causing damage to agricultural and horticultural crops in Holland. In Holland there appear to be seven species of Pratylenchus, viz., P. pratensis, P. penetrara, P. thornei, a species close to P. scribneri and three species close to P. minyus. Tylenchorhynchus spp. and Rotylenchus erythrinae were also found. The damage done by these eelworms is often considerable.
