Cornell University. College of Agriculture and Life Sciences.

For the last seven decades, Cornell University’s College of Agriculture and Life Sciences (CALS) has been leading the fight against nematodes—invasive, microscopic worms that can destroy seasons' worth of crops. However, researchers had been working in a facility that lacked the infrastructure to keep pace with their innovative work. On August 1, 2019, thanks to a $1.2 million grant from New York State and another $400,000 in federal funding, CALS cut the ribbon on the new Golden Nematode Quarantine Facility, located on the Cornell campus in Ithaca, NY. The facility is the only research program in North America with expertise in biology, resistance breeding and management of potato-cyst nematodes. At the lab, Cornell scientists work in tandem with the U.S. Department of Agriculture (USDA) Agriculture Research Service (ARS).

GLOBAL: Globodera Alliance.
GLOBAL is a five-year $3.2 million project funded by USDA. The project title is "Risk assessment and eradication of Globodera spp. in U.S. production of potato", with research focused on the potato cyst nematodes Globodera pallida (pale cyst nematode), G. rostochiensis (golden nematode), and the related species G. ellingtonae that has recently been found in Oregon and Idaho. GLOBAL stands for "Globodera Alliance", a group of 17 research, extension, and education professionals, located in Idaho, Oregon, New York, Canada, Scotland, and France. GLOBAL members include faculty from the University of Idaho, Oregon State University, Cornell University, US Department of Agriculture (USDA), Agriculture and Agri-Food Canada, The James Hutton Institute, and the French National Institute for Agricultural Research.
