Green manure crops are important to avoid erosion and leaching of nitrogen in surface water during the intercrop season in temperate agriculture. Therefore their use is stimulated by local and European policy. However, the presence of green manure crops could facilitate population build-up of plant-parasitic nematodes. Knowledge on the host-plant status of these crops for plant-parasitic nematodes is of paramount importance to avoid problems in subsequent cash crops. Ideally, resistant cultivars of green manure crops are used when plant-parasitic nematodes are present. Brassica juncea (brown mustard) caused mortality of encysted eggs of Globodera pallida after incorporation in the soil. Eruca sativa (arugula) has shown potential as a trap crop for M. hapla. We examined the host plant status of B. juncea cv. ISCI99 and E. sativa cv. Nemat for Meloidogyne chitwoodi and M. fallax. The two nematode species were able to reproduce on both crops, but more egg masses were produced by M. fallax than by M. chitwoodi. In vitro, the life cycle duration of M. chitwoodi and M. fallax on B. juncea and E. sativa was 765 degree days (base 5°C), indicating a delayed development. In a field experiment, the number of juveniles of M. chitwoodi in the soil was monitored under E. sativa and black fallow. The effect of E. sativa as a green manure crop on the population of M. chitwoodi was comparable with that of black fallow and there was no evidence that E. sativa acted as a trap crop. Based on our results, B. juncea cv. ISCI99 and E. sativa cv. Nemat can be used as green manure crops in the intercrop season, but they should be destroyed before M. chitwoodi and M. fallax can complete their life cycle.
