The American Phytopathological Society

The American Phytopathological Society For all of those who are current members of the American Phytopathological Society or who have interests in Plant Pathology or related plant and soil sciences.

The American Phytopathological Society (APS) is the premier society dedicated to high-quality, innovative plant pathology research. For more than a century, members of APS have been making and sharing significant breakthroughs, both for the science and society. APS is driven by a distinctive community of scientists, whose energy and commitment ensure the global advancement of this critical science. APS members represent a broad range of specialties, from pushing frontiers in the accuracy and speed of field diagnosis, to increasing our understanding of plant pathology through laboratory research. Members come from academia, government, industry, and private practice. The diversity of the members and science makes the society pertinent to a multitude of research areas, while the international involvement ensures that the latest innovations from around the world are available to all. Share/follows ≠ endorsement.

Reliable, up-to-date fungal and oomycete taxonomy underpins every aspect of plant pathology by enabling accurate pathogen identification, robust host-range analyses, clear assessment of geographic spread, and the development of effective disease management strategies. Yet, despite major advances in systematics and molecular phylogenetics, the integration and use of current names in applied plant pathology remains inconsistent.

To enhance the accuracy, reproducibility, and long-term value of fungal pathogen research, Michael J. Bradshaw et al. propose the following recommendations:

1) Use current names
2) Adopt 𝘊𝘰𝘥𝘦-compliant terminology
3) Collaborate with taxonomic experts
4) Prioritize education and training
5) Require proper deposition of voucher material
6) Support curated tools and databases

In applied plant pathology, taxonomy and nomenclature are not merely academic concerns; researchers generate the correct identifications and reference data that diagnosticians, extension personnel, and industry translate into reliable diagnostics, fungicide efficacy and resistance management, regulatory information, and economically efficient disease management.
