National Plant Diagnostic Network

The National Plant Diagnostic Network (NPDN) is a collaborative effort among agricultural and plant health agencies across the United States. Its purpose is to quickly detect, identify, and respond to plant diseases, pests, and harmful invasive species. By sharing expertise, lab resources, and information, NPDN helps protect crops, forests, and ecosystems from threats that can damage agriculture and natural resources. This proactive approach ensures faster response times, minimizes economic losses, and helps sustain healthy plant life nationwide.
