PAPAS Project Director Dr. Louise-Marie Dandurand takes the stage at the 13th World Potato Congress in Kenya to present “PAPAS: Addressing the Challenges of the Invasive Potato Cyst Nematodes in the United States” on Wednesday, October 28, 2026.
The pale cyst nematode has cost Idaho potato growers tens of millions of dollars and threatened export markets. A new article by PAPAS researchers in AGDAILY explains what growers need to know about the path forward for PCN management in Idaho — and it calls for integrating every tool available.
Quick, reliable test differentiates key PCN species with simple equipment. A recently published article from PAPAS researchers Chandni Shah, Ph.D., and Louise-Marie Dandurand, Ph.D., summarizes their work in developing a faster, more reliable method of differentiating potato cyst nematode species — in the lab or in the field.
Nematode soil sampling is not a one-size-fits-all approach. The right number, depth, and location of samples depends on the field, the target species, and the level of precision needed for management decisions. Understanding how nematode population densities and dispersal patterns vary by species helps growers and their advisors build better sampling programs to manage these pests more effectively.
The Potato Association of America (PAA) Annual Meeting comes to New Orleans, Louisiana this July 26–30. On Monday, July 27, PAPAS team members will lead and present in the main symposium, Innovative Paths to Nematode Control, a dedicated session bringing together some of the country’s leading researchers on potato nematode management to share the latest…
A new study from the PAPAS project and the University of Idaho PCN research team published in Plant Disease sheds new light on the risk posed by the introduction of non-native populations into U.S. production regions.
A recent article by PAPAS researchers summarizes 20 years of potato cyst nematode research through the University of Idaho Potato Cyst Nematode (PCN) research program.
For most nematode species causing the greatest economic damage to U.S. potato growers, commercially viable resistant varieties simply do not exist. See how the PAPAS project is working to ensure U.S. potato growers have resistant variety options for the full range of economically important nematode species across market classes.
PAPAS, NEM-EMERGE, and PCN Action Scotland presented a first-of-its-kind joint stakeholder workshop, bringing together researchers, policymakers, and potato growers to discuss sustainable management strategies.
PAPAS researchers will be on the ground in Oregon and Washington, sharing the latest in nematode management research directly with growers, agronomists, and industry partners.
