Eso obliga a repensar cuánto de lo natural puede reemplazar a lo tradicional sin perder cosecha. La alternativa sirve, pero todavía no reemplaza. Las cosas que cuidan la tierra suelen costar más paciencia que las que prometen resultados inmediatos.","quienFirma":"Universidad no identificada en el preprint","confianza":"preprint","consulta":null},"sello":{"hash":"ea305c6202c2bfa37a7bb074e3d153ea6c22506bd70f355d169aef655da2f02c","sello":"193bdd7c36f114d706612cf88712da9cbc3064d144b8898518d28c78c46f426a","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6583686,"aleatorio":"4f8fce4a05fbe4089eba6112d19ac99867e7f4f7af9befca10d480e758c43c73","tiempo":"2026-10-25T15:20:00.000Z"},"nist":{"cadena":2,"pulso":1999036,"salida":"F7331E5C5931ADF34187C4BAF41FD080446C8D7F44E37E183A3F2ED785AF6CF61E80BED51857F378219964CEDE8B74C758C7D6D5C50074F84D0984ED528F41B7","tiempo":"2026-10-25T15:19:00.000Z"},"noAntes":"2026-10-25T15:20:00.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 25 15:20:32 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Building Bridges Belowground: Pythium oligandrum En-hances Rhizosphere Network Connectivity","descripcion":"Biological control agents (BCAs) offer a potential sustainable alternative to fungicides for crop dis-ease management, but their effects on resident plant microbiomes and microbial interactions remain poorly understood. Here, we investigated the effects of the BCA Pythium oligandrum on disease con-trol and the rhizosphere microbiome of starch potato cv. Kuras in a field trial. We compared a labora-tory strain and a commercial formulation (Polygandron) with commonly used fungicides during early blight development. The laboratory strain suppressed early blight at plant senescence, but this effect did not persist until harvest, whereas fungicide treatment provided near-complete disease suppress","pubDate":"2026-10-25","url":"https://www.biorxiv.org/content/10.64898/2026.10.22.761010v1?rss=1"},"indexado":"2026-10-25T15:20:00.158Z"}}
