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

open access: yesPest Management Science, EarlyView.
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.

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

open access: yesPest 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.

Geosmithia species associated with fir-infesting beetles in Poland

open access: yesActa Mycologica, 2018
Geosmithia species (Ascomycota: Hypocreales) are common ectosymbionts of scolytine bark and ambrosia beetles that feed on coniferous and deciduous trees in different forest ecosystems.

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

open access: yesPest Management Science, EarlyView.
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.

Democratisation in the European Neighbourhood. CEPS Paperback. October 2005 [PDF]

open access: yes, 2005
This is the first state-of-the-art work on the process of democratisation in the wider European neighbourhood since the seminal events of 2004, with the EU's enlargement and the Orange, Rose and Cedar Revolutions beyond.

Scientific Opinion on the risk to plant health of Xanthomonas citri pv. citri and Xanthomonas citri pv. aurantifolii for the EU territory [PDF]

open access: yesEFSA Journal, 2014
The Panel conducted a pest risk assessment for Xanthomonas campestris (all strains pathogenic to Citrus) for the EU territory and an assessment of the effectiveness of present EU requirements against Xanthomonas strains pathogenic to citrus.

Phosphite formulations for control of European apple canker

open access: yes, 2022
 The aim of the present study was evaluate the effect of different phosphite formulation for the control of European apple canker (EAC). The products in vitro were incorporated in PDA medium and the development of Neonectria ditissima wasevaluated. Fruit and apple plants were wounded, followed by treatments and inoculation with N. ditissima in laboratory

Discovery and characterisation of succinate dehydrogenase inhibitor resistance in Plenodomus biglobosus (phoma stem canker of oilseed rape)

open access: yesPest Management Science, EarlyView.
SDHI resistance is reported and characterised for the first time in the oilseed rape phoma stem canker pathogen Plenodomus biglobosus (Leptosphaeria biglobosa). We investigate cross‐resistance patterns, associated SDH target‐site mutations, possible fitness costs, and consider the implications for disease and resistance management.

Decreased DMI sensitivity of Plenodomus biglobosus (phoma of oilseed rape) associated with CYP51 substitution G476S

open access: yesPest Management Science, EarlyView.
Here, we report for the first time a target site mutation in the CYP51 gene of the oilseed rape phoma stem canker fungus Plenodomus biglobosus (Leptosphaeria biglobosa) that is associated with decreased sensitivity to sterol demethylation inhibitor fungicides.
