Ravi que notre petit projet #MemoRust ait été retenu par #SuMCrop @inrae-france.bsky.social ! A l’interface phytopathologie–histoire des sciences et rurale, avec pour cas d’étude la rouille noire en France, nous analyserons les mécanismes de construction, transmission et oubli des savoirs.

Très touché par mon cadeau de 'Secret Santa' @inrae-bioger.bsky.social, si bien ciblé ! 🤣/🥹

Our colleague Dr Pierre-Yves Teycheney, a highly respected plant virologist, is currently facing disciplinary sanctions imposed by CIRAD that appear disproportionate in light of the documented facts and circumstances. You can sign the letter of support here 👇 www.ipetitions.com/petition/let...
