Globodera rostochiensis
''Globodera rostochiensis'', commonly known as the golden nematode, golden eelworm or yellow potato cyst nematode, is a plant pathogenic nematode. It is a pest of plants in the family Solanaceae, primarily infesting potatoes and tomatoes, as well as a variety of other root crops.
== Pathology ==
The golden nematode negatively affects plants of the family Solanaceae by forming cysts on the roots of susceptible species. The cysts, which are composed of dead nematodes, are formed to protect the female's eggs and are typically yellow-brown in color.〔 The first symptoms of infestation are typically poor plant growth, chlorosis, and wilting. Heavy infestations can lead to reduced root systems, water stress, and nutrient deficiencies, while indirect effects of an infestation include premature senescence and increased susceptibility to fungal infections.〔
Symptoms of golden nematode infestation are not unique, and thus identification of the pest is usually performed through testing of soil samples.〔 An infestation may take several years to develop, and can often go unnoticed for between five and seven years. After detection, however, it may take up to thirty years for the pest to be effectively eradicated.〔
