National Meeting 2022 - Posters | National Plant Diagnostic Network

🔔 After 24 years of continuous USDA NIFA cooperative agreement support, delays in the next funding opportunity have required NPDN to strategically scale back operations. Remaining funds under a no-cost extension are being used to preserve critical infrastructure and sustain essential national functions. As of September 1, 2026, network activities will be paused or operate at reduced capacity, with full operations expected to resume when the next cooperative agreement and associated funding are in place.
