Golden nematode

Globodera rostochiensis

Golden nematode (Globodera rostochiensis) is a nematode pest of potatoes. It is a native of Europe and was first detected in New York in 1941.

These nematodes are a serious pest of solanaceous plants. Patches of poor growth with yellowing or wilting of foliage are the first indicator of their presence. With a heavy infestation cysts are visible on the roots with the naked eye. Cysts are the hardened body of the female nematode swollen with eggs. They are spherical in shape and attached to the root by a stalk. Cysts start out white then turn a golden yellow color and finally turn brown. Control is available by growing resistant varieties.
