The epidemiology of the blackleg pathogen, Leptosphaeria maculans, impacts fungicide resistance management strategies

Pest Management Science, EarlyView.
Understanding how infection timing drives disease is essential for the development of fungicide resistance management strategies. For blackleg disease of canola, all infection timings can contribute to the following generation, therefore all fungicide applications have the ability to select for resistance.

Molecular diagnostic methods can prevent unnecessary rejection of organic seed lots [PDF]

, 2004
In some years, large amounts of organic seed lots are discarded due to the presence of high levels of seed-borne diseases. In barley it is especially the presence of the fungal species Pyrenophora teres (barley net blotch) and P.

Registration of ‘VT Beahm’ winter forage barley

Journal of Plant Registrations, Volume 20, Issue 2, May/August 2026.
Abstract ‘VT Beahm’ (Reg. no CV‐384, PI 702638) is an awnless, six‐row barley (Hordeum vulgare L.) cultivar with a winter growth habit. VT Beahm was released by the Virginia Agricultural Experiment Station in May 2021. Prior to being named, VT Beahm was tested under the experimental designation VA16BFHB‐268 NA.

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

Molecular 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 ...

Association mapping reveals a reciprocal virulence/avirulence locus within diverse US Pyrenophora teres f. maculata isolates

BMC Genomics, 2022
Background Spot form net blotch (SFNB) caused by the necrotrophic fungal pathogen Pyrenophora teres f. maculata (Ptm) is an economically important disease of barley that also infects wheat.

Genetic Differentiation in the SdhC Subunit Confers Intrinsic Resistance to SDHI Fungicides in Fusarium asiaticum

Molecular Plant Pathology, Volume 27, Issue 5, May 2026.
In Fusarium asiaticum, two homologous SdhC subunits (FaSdhC1/C2) regulate sensitivity to SDHI fungicides: deletion of FaSDHC1 decreases sensitivity, while deletion of FaSDHC2 increases it. Multiple mutations in ΔFaSDHC2 confer resistance to SDHI fungicides.

Challenges facing the management of pesticide resistance in weeds, diseases and insect pests in European agriculture and the future of effective IPM implementation

Pest Management Science, Volume 82, Issue 4, Page 2838-2843, April 2026.
Opinion on pesticide resistance and management in the European Union (EU) and United Kingdom (UK) is presented cognisant of changes in regulation that impact on mode of action availability and cropping system choice. Abstract In recent times, pesticide resistance has been managed reasonably effectively, either proactively or reactively, by monitoring ...

Resistance of barley accessions from the East Asian Center of crop diversity to the net and spot forms of the net blotch pathogen

Труды по прикладной ботанике, генетике и селекции
Background. Barley is a major fodder crop and valuable raw material for the brewing industry. A harmful disease of barley is net blotch, caused by the hemibiotrophic fungus Pyrenophora teres Drechsler, which exists in two forms that differ in symptoms on
