Population Genomic Analyses Reveal Geographic Structure in Rhizoctonia solani AG1‐IA Isolates Associated With Agronomic Crops

open access: yesMolecular Ecology, Volume 35, Issue 9, May 2026.
ABSTRACT Soilborne fungal pathogens threaten food security, but limited knowledge of their population biology, including genetic variability and population structure, hinders the development of effective strategies to prevent crop losses. Rhizoctonia solani AG‐1 is a significant soilborne pathogen worldwide, divided into subgroups based on host range ...

A new method to measure EC50 reveals cultivar‐specific fungicide resistance and very high diversity within experimental field populations of Zymoseptoria tritici

open access: yesPest Management Science, Volume 82, Issue 4, Page 3613-3624, April 2026.
We isolated Zymoseptoria tritici strains from a diverse wheat field and quantified fungicide resistance using a novel plate assay. We found high diversity in fungicide sensitivity and host–fungicide–pathogen interactions. Abstract BACKGROUND Zymoseptoria tritici causes Septoria tritici blotch (STB), the most damaging wheat disease in Europe. In Europe,

Molecular Mechanism Underlying Resistance Variation to the Novel Agrochemical Quinofumelin in Fusarium graminearum

open access: yesMolecular Plant Pathology, Volume 27, Issue 4, April 2026.
The D155T, V179E, V179D and N281A mutations in FgDHODHII altered the binding mode of quinofumelin, resulting in diminished affinity and a negative correlation between binding affinity and the resistance level of these mutants. ABSTRACT Quinofumelin, a quinoline‐based fungicide, demonstrated potent antifungal activity against Fusarium graminearum, the ...

Biocontrol Potential of Rhizosphere Fungi Against Pyricularia Oryzae in Ciherang Rice Variety [PDF]

open access: yesBIO Web of Conferences
Blast disease is an important disease of rice caused by Pyricularia oryzae. The use of antagonistic fungi from the rhizosphere of rice plants has the potential to control plant pathogens. One of them is from the genus Aspergillus.
