Management of Nematodes of Andean Tuber and Grain Crops.

The exploitation of different Andean crops, including oca, ulluco, mashwa, quinoa and lupine, is revised, for integrated management of plant parasitic nematodes such as Globodera spp., Nacobbus aberrans and Thecavermiculatus andinus, in potato and other Andean crops. The effects of selected lines and varieties in rotations with potato are discussed, with particular attention to the eggs hatching effects and nematodes reproduction. Knowledge on the relationships (host/non host and trap/antagonist crop) among Andean crops and their most important parasitic nematodes appears very important. Some lines were identified which could play an important role in the future implementation of an integrated management of soil nematodes, with long-term benefits for Andean traditional agricultural systems.
