Interpretive Summary: Plant-parasitic nematodes are microscopic roundworms that attach the roots of plants resulting in yield loss to agricultural crops. Additional, non-chemical methods are needed to control these important agricultural pests. One such method may be the use of plants that either kill nematodes or do not allow them to reproduce in roots. Research was conducted on one such plant called litchi tomato. Several different plant-parasitic nematodes were added to litchi tomato roots and reproduction and invasion evaluated. It was discovered that litchi tomato is not a host for a diversity of plant-parasitic nematodes. These findings will be used by growers and researchers as part of an integrated nematode management plan.

Technical Abstract: Plant-parasitic nematodes cause economic damage to a number of agricultural crops in the Pacific Northwest of the United States. Of particular concern are the root knot nematodes, M. hapla in potato, vegetables, and wine grape production and M. chitwoodi damage to potato tubers, and the potato cyst nematode, and Globodera pallida which is of quarantine concern in Idaho. Solanum sisymbriifolium has been proposed as a strategy to manage plant-parasitic nematodes. The goal of this research was to evaluate the reproduction and invasion of M. hapla, M. chitwoodi and G. pallida on S. sisymbriifolium. Reproduction of these plant-parasitic nematodes was minimal or nonexistent on S. sisymbriifolium, with few or no eggs recovered. In invasion assays, M. chitwoodi did not invade S. sisymbriifolium roots seven days post inoculation. In the same short-term assay, M. hapla was able to invade S. sisymbriifolium roots (5.3% to 5.9% M. hapla second-stage juveniles in roots compared to tomato) but did not develop. Similar to M. hapla, over a 10-week period, G. pallida invaded S. sisymbriifolium roots, but rarely developed to a third-stage juvenile and never to female. The resistance of S. sisymbriifolium to M. hapla, multiple races of M. chitwoodi, and G. pallida indicates there is the opportunity for widespread deployment of this trap crop.
