Golden Nematode

Eisenback, Virginia Polytechnic Institute and State University,]Golden nematode (Globodera rostochiensis) is a serious agricultural and quarantine pest. The United States positively identified G. rostochiensis in 1941 in a potato field in New York that had been a staging area for military equipment returning from World War I. Mud on the tires of returning vehicles likely spread the nematode.  Cysts of the nematode can live in soil for 30 years and the nematode can cause direct crop losses, increase pest control costs, constrain cropping patterns, and devalue infested land. Potatoes and tomatoes are the principal crops of economic importance attacked by this pest. The nematode also reproduces on the roots of eggplant and on some wild solanaceous weeds. Quarantine measures and crop rotations of G. rostochiensis-resistant potato varieties with non-host crops are successful control strategies that have contained the nematode to portions of New York. There are no current impacts on interstate or international trade, other than certain survey and certification requirements, because the United States has G. rostochiensis under effective control and containment.
