National Plant Diagnostic Network.

First Detector, a program of the National Plant Diagnostic Network (NPDN), equips a nationwide network of individuals to rapidly detect and report the presence of invasive, exotic plant pathogens, arthropods, nematodes, and weeds. If you suspect the presence of a high-impact plant pest or pathogen, contact a diagnostician and submit a sample for diagnosis.
