About ASTA Pest Database for Seeds (PeDS)

Methodology for adding pests to the database:

ASTA is made aware of pest issues through several sources including those that are listed in WTO notifications of proposed regulations; pest lists from import permits; and pests that are responsible for shipment rejections. Companies and other stakeholders are encouraged to notify ASTA whenever they encounter a seed related pest-specific phytosanitary problem.

Once a pest is identified for inclusion into PeDs, an extensive literature search is conducted. ASTA uses the same processes, procedures, and rules as are used for the International Seed Federation’s (ISF) Regulated Pest Database. Primary sources of information include the CABI database, EPPO database, ISTA, computer literature and library searches. As these databases often contain abstracts and other references that have not been replaced with peer reviewed articles, are contradictory, or do not contain the latest articles, ASTA reviews all citations and selects the ones that contain the latest relevant information, scientific scrutiny, and interpretation. All data sheets are then peer reviewed prior to entry into PEDs. These pest data sheets are reviewed/updated every 3 years.

Relationship to other seed pest databases:

PeDS compiles information about pest names, distribution, and hosts from the CAB International Crop Protection Compendium and the USDA ARS Fungal Databases. For consistency, scientific names for pests were harmonized with the Crop Protection Compendium. Information is also obtained directly from scientific journals for the most current and emerging pests that may not be in other databases yet.

Whenever possible, PeDS is harmonized with the ISF Regulated Pest List Database. The ISF regulated pest database is similar to PeDS in terms of what pest information is included; however, there is one major distinction. The ISF database is organized by commodity. The ISF database contains information on all pests that are collectively regulated globally for a given commodity. Currently there are datasets for 14 seed commodities with a database on maize nearing completion. PeDS is organized by pest species and does not contain information on pests that are already in the ISF database for those commodities. Pest species in PeDS are associated with commodity seed species that are not yet in the ISF database. Terminology and other parameters used in the ISF database are the same as are used in PeDS. As ISF adds commodity species to its database, these two databases will eventually merge over time.

USDA APHIS Phytosanitary Export Database (PExD):

USDA APHIS maintains thePhytosanitary Export Database (PExD) which is a database of phytosanitary requirements of most countries in the world for US-origin seed. ASTA works closely with APHIS to update information in PExD based on its reviews, updates, and analyses of pest information. As a result, pests’ species can be added or removed, and phytosanitary measures such as seed treatments or seed health testing requirements can be updated.

About ASTA

Founded in 1883, the American Seed Trade Association (ASTA) is one of the oldest trade organizations in the United States. Its membership consists of over 700 companies involved in seed production and distribution, plant breeding, and related industries in North America. As an authority on plant germplasm, ASTA advocates science and policy issues of industry-wide importance. ASTA’s mission is to be an effective voice of action in all matters concerning the development, marketing and movement of seed, associated products and services throughout the world. ASTA promotes the development of better seed to produce better crops for a better quality of life.

About the technical expert:

Darrell Maddox, Endless Sky Partners, manages the PeDS database for the ASTA. Mr. Maddox has over 35 years’ experience in seed related companies, including 20 years as president of the independent STA Laboratories (now Eurofins BioDiagnostics) providing seed health testing, seed quality testing and genetic testing to the seed industry. Darrell helped charter and established the National Seed Health System (NSHS) accreditation program, the Systems Approach to Nursery Certification (SANC) program, National Seed Health Accreditation Pilot Program (NSHAPP), Regulatory Framework for Seed Health (ReFreSH) and was instrumental in organizing the International Seed Health Initiative to standardized seed health techniques throughout the world. Darrell has worked with the ASTA as a Technical Consultant since 2014.
