No Silver Bullet for Pale Cyst Nematode: PAPAS Research Featured in AGDAILY
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.

PAPAS Delivers New Tool for Potato Cyst Nematode Identification
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.

Build a Smarter Nematode Sampling Program for Better Management
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.

Closing the Gap in Nematode-Resistant Potato Varieties
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.
