Sensitivity of Irish Pyrenopeziza brassicae populations to methyl benzimidazole carbamate (MBC), quinone outside inhibitor (QoI) and succinate dehydrogenase inhibitor (SDHI) fungicides

Pest Management Science, Volume 82, Issue 11, Page 10818-10827, November 2026.
For three collections of Irish Pyrenopeziza brassicae populations fungicide sensitivity status to methyl benzimidazole carbamate (MBC), quinone outside inhibitor (QoI) and succinate dehydrogenase inhibitor (SDHI) fungicides was determined using sensitivity screening in vitro. Molecular mechanisms of insensitivity have been identified for MBC and QoI in

Determining frequencies of fungicide resistance in Leptosphaeria maculans that render demethylation inhibitor fungicides ineffective in the field

Pest Management Science, Volume 82, Issue 11, Page 10796-10805, November 2026.
As little as 1–10% of the population is needed to be resistant for demethylation inhibitor fungicides to be rendered ineffective. Following a single round of selection, the frequency increases by more than 15% with limited fitness penalty detected when no selection is present.

Disease control in oilseed rape: Current insights and perspectives for next‐generation integrated pest management

Pest Management Science, Volume 82, Issue 11, Page 10572-10589, November 2026.
Winter oilseed rape in Europe suffers frequent pathogen losses. This review outlines key integrated pest management (IPM) strategies, rotation, residue and tillage management, optimized sowing, resistance, and targeted fungicides supported by forecasting.

In vivo sensitivity of Phakopsora pachyrhizi to fungicides [PDF]

Ciência Rural, 2019
: Asian soybean rust is one of the most destructive diseases that can be found in this crop. It can be largely controlled by fungicide application. The objective was to assess the sensitivity of P. pachyrhizi isolates to fungicides.

Modelling Resistance Management Benefits of Incomplete Cross‐Resistance Within a Fungicide Mode of Action Group

Evolutionary Applications, Volume 19, Issue 11, November 2026.
ABSTRACT Mixing fungicides with different modes of action (MoA) is a well‐established resistance management tactic which relies on the general absence of cross‐resistance between MoAs. Mixtures of fungicides with the same MoA and complete cross‐resistance are not expected to contribute to resistance management.

Mutations in the SdhB and SdhD Genes Confer Resistance to Succinate Dehydrogenase Inhibitor Fungicides in Australian Populations of Leptosphaeria maculans

Molecular Plant Pathology, Volume 27, Issue 11, November 2026.
Resistance to the SDHI fungicides is discovered and characterised in a major oilseed pathogen, Leptosphaeria maculans. Mutations are found in genes encoding two subunits of the SDH complex, and their prevalence assayed in populations. ABSTRACT Fungicide resistance is a threat to the control of fungal diseases of crops and humans. Leptosphaeria maculans

Comparative genomics reveals lineage‐associated structural variation and diversification in a barley fungal pathogen

New Phytologist, Volume 252, Issue 4, Page 1565-1583, November 2026.
Genome‐wide copy‐number variation landscape highlights structural divergence across Puccinia hordei isolates and potentially links Cyp51 amplification to fungicide insensitivity. Summary Leaf rust, caused by Puccinia hordei, is a major barley disease worldwide.

Improved Management Efficacy of Late Leaf Spot on Peanut Through Combined Application of Prothioconazole with Fluxapyroxad and Pyraclostrobin

Agronomy, 2020
Late leaf spot, caused by Nothopassalora personata, is the most economically important fungal disease affecting peanut foliage in South Carolina and can result in combined management and yield loss costs of greater than 490 dollars/ha.

Structural and Functional Elucidation of Yeast Lanosterol 14α-Demethylase in Complex with Agrochemical Antifungals. [PDF]

PLoS ONE, 2016
Azole antifungals, known as demethylase inhibitors (DMIs), target sterol 14α-demethylase (CYP51) in the ergosterol biosynthetic pathway of fungal pathogens of both plants and humans.
