Summary

The pest has been detected in one field in eastern England which was pre-emptively tested for free-living nematodes by the grower, prior to any crop being planted. Subsequent official sampling and testing has confirmed the presence of M. chitwoodi.

Danger

Meloidogyne chitwoodi is a root-knot nematode which is an important pest of Solanum tuberosum (potato) and S. lycopersicum (tomato). The internal necrosis and external swelling of potato tubers infested with M. chitwoodi can result in the reduction in the market value of the crop. Meloidogyne chitwoodi infestation can reduce potato tuber yields and tubers can continue to develop symptoms during storage. (Hoyle et al., 2023)
