Temporal dynamics of co‐inoculation of Leptosphaeria maculans and Leptosphaeria biglobosa determine interspecific competition and disease development on oilseed rape

Pest Management Science, EarlyView.
This study provides evidence that the timing of co‐inoculation of Leptosphaeria maculans and Leptosphaeria biglobosa determine the outcome of interspecific competition and disease development on their host oilseed rape. Abstract BACKGROUND Phoma stem canker is one of the most economically damaging diseases of oilseed rape, caused by co‐existing fungal ...

Phosphite formulations for control of European apple canker

, 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

Comparing methods to determine European canker resistance in apple tree accessions

New Zealand Plant Protection, 2010
Pruning cuts made in summer and pruning cuts leaf scars and score wounds made in autumn were inoculated to compare their suitability to discriminate for European canker resistance among apple accessions When pruning cuts were inoculated in summer the mean lesion size varied between accessions with Royal Gala displaying significantly larger lesions than

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

Pest 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.

Prevalence, Distribution and Identification of Phytophthora Species from Bleeding Canker on European Beech [PDF]

Journal of Environmental Horticulture, 2010
Abstract While bleeding canker of European beech trees (Fagus sylvatica) has long been recognized as a problem in Europe and North America, the cause in the northeastern United States has not been clear. To resolve this, we surveyed for disease prevalence on European beech, identified the pathogens involved, proved their pathogenicity, compared

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.
