Golden nematode a major threat to American potatoes
The golden nematode, Heteradera rosto chiensis, is a severe pest reducing edible potato yields and spreading in temperate regions. After appearing in Nassau Suffolk on Long Island, it was found in Steuben County New York in 1963 and New Castle Delaware in 1969. Cysts attach to roots, hatch in spring, and larvae rob plants of water and nutrients. A New York state quarantine since 1944 restricts movement of potatoes and related products while federal and state programs, led by the USDA Agricultural Research Service, expand detection and containment efforts.
