Potato Cyst Nematodes -
Globodera rostochiensis (golden nematode) &
|? Both PCNs are internationally-|
recognized quarantine pests of potato.
? The PCN known as golden nematode
was discovered in NY in 1941. It has
been successfully confined to nine
counties in New York.
|? The PCN known as pale cyst nematode was discovered in Idaho in 2006. |
? Both nematodes reside in Canada with recent discoveries of the golden nematode
in Quebec and in seed production fields in Alberta.
? Both species of PCNs are distributed in potato-growing areas worldwide.
Why are PCNs a Threat to US Agriculture?
? Once PCNs are introduced, eradication is difficult and perhaps unlikely.
|from the regulated areas and carrying soil (e.g. all nursery, turf, root, and tuber crops) in the regulated areas.|
|? PCN control requires strict adherence to regulatory and quarantine procedures and|
annual surveys of infested and potentially exposed lands.
? Commercially marketable PCN-resistant potatoes are grown in affected fields.
? In NY, the USDA-APHIS and the New York State Department of Agriculture and Markets
work cooperatively with research and extension leaders and with growers to
implement appropriate nematode management plans.
|? The joint ARS-Cornell PCN-research program is the only program in North America that has extensive expertise in PCN|
biology, resistance breeding, and PCN management strategies, and it plays a vital role for PCN control in the U.S.
? Our research program focuses on four major areas:
-Develops and releases PCN-resistant potato varieties.
-Uses molecular tools to develop diagnostics for faster identifications.
-Uses multiple technologies to discover novel approaches to PCN management.
-Provides scientific & technical support to USDA-APHIS and NYS nematode quarantine programs.
