ISTA Reference Pest List (2019-04)
A list of seed-borne and seed transmitted pathogens associated with seed of Cotton, Sorghum, Soybean, Sunflower, Triticale and Wheat.

How to read the updated annotated list
Plants: The crop name and its binomial nomenclature (species); the names of the diseases.
Pests: Their current nomenclature, all the synonyms according to the databases Species 2000 & ITIS Catalogue of Life and the Index Fungorum; their taxonomy (kingdom, phylum).
Is the crop a host for the pest? The answer is ‘Yes’, if the pest is pathogenic on the crop, causing disease. Otherwise, the answer is ‘No’. When the current knowledge is unclear or without strong support to a decision, the answer is ‘Not proven’.
Is the pest a pathogen or saprophyte? The answer is ‘Saprophyte’, if the pest only infests seeds during non-adapted storage conditions, or if it is associated with seeds without causing diseases on seedlings. Otherwise, the answer is ‘Pathogen’. When the current knowledge is unclear or without strong support to a decision, the answer is ‘Not proven’.
*Seeds as a pathway for pest dissemination:
Is the pest seed-borne or seed-transmitted? The answers to these questions are based on scientific articles and due to the expertise of the worldwide panel of reviewers. When the conclusions are supported by our current scientific and practical (field experience) knowledge, the response is ‘Yes’ (it is proven that the pest isseed-borne or -transmitted) or ‘Not’ (it is proven that the pest is not seed-borne or -transmitted). When the current knowledge is unclear or without strong support to a decision, the answer is ‘Not proven’.
Is seed a pathway for pests? The answer to this question is ‘Yes’ for all the seed-transmitted pests and for seed-borne pests that can be introduced and disseminated; ‘No’ for non-disseminated pests and saprophytes; ‘Not proven’ when scientific evidence is still lacking or currently unclear.
Experimental design and results: A summary of the experiments performed in the laboratory and in the field to characterise the role of seeds in pest-crop interactions.
Remarks: Notes about the reference analysed.
References: Article source that was used to support the conclusions.
*Completeness of the list:The list is expected to evolve regularly, due to novel scientific evidence of the seed-borne/-transmitted status for a known pest, or after identification of a novel pest for a given crop. A continuous literature survey guarantees to be well-timed with novel discoveries and to provide accurate information on the webpage. However, it takes time to rigorously evaluate the scientific literature and some pests still under consideration are explicitly mentioned.
