The collection of digital images is provided as a service to Arkansas agriculture. These images represent symptoms of both pathological (infectious) and non-pathological (physiological/environmental) disorders of agronomic row crops and horticultural crops that grow in Arkansas. These photos are useful as an identification tool to growers of the crops listed.

University of Arkansas. Cooperative Extension Service.
University of Georgia. Center for Invasive Species and Ecosystem Health.
Early Detection and Distribution Mapping System (EDDMapS), provides a more accurate picture of the distribution of invasive species. EDDMapS will allow land managers, agencies, and others to set priorities for early detection and rapid response (EDRR), as well as formulate overall invasive plant management action plans. EDDMapS provides online tools for citizens to report invasive species sightings and maps these sightings to provide distribution information by species, state, and county.
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.
Nature Conservancy. iMapInvasives.
Includes a variety of published guides and internet resources (videos) for use in identifying invasive species that are found in the participating states, provinces, and regions of the iMapInvasives network. The iMapInvasives network is currently comprised of various U.S. states and one Canadian province (Arizona, Florida, Kentucky, Maine, New York, Oregon, Pennsylvania, Vermont, Virginia, and West Virginia, and in Canada - Saskatchewan).
Aquatic Nuisance Species Task Force.
This database was designed to direct users to invasive species experts. The public portion of the database will guide you to a state contact who acts as a filter for information and identifications.

National Plant Diagnostic Network.
NPDN is a national network of diagnostic laboratories that rapidly and accurately detect and report pathogens that cause plant diseases of national interest, particularly those that could be deemed to be a biosecurity risk. The specific purpose of the NPDN is to provide a cohesive, distributed system to quickly detect and identify pests and pathogens of concern.
Oregon State University. National Pesticide Information Center (NPIC).
Whether your pest is a weed, insect, animal, microbe, or another organism, correct identification of your pest makes controlling it easier and often more effective.
Michigan State University. Midwest Invasive Species Information Network.
The invasive species education modules will help you become more comfortable with identifying these species in the field. Includes detailed information for terrestrial plants, aquatic plants, crustaceans, fish, insects, mollusks, and pathogens. Each module includes a short ten question quiz at the end to help you assess your newly acquired knowledge.
