Kiwifruit bacterial canker in 'Hayward' kiwifruit : the application of observational study design and epidemiological techniques to the study of disease outbreaks affecting plant health : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Veterinary Epidemiology, Institute of Veterinary, Animal and Biomedical Sciences at Massey University, Manawatu, New Zealand [PDF]

, 2017
Bacterial canker of kiwifruit, caused by Pseudomonas syringae pv. actinidiae (Psa) biovar 3, was first recorded in New Zealand in November 2010 and quickly made production of the goldfleshed kiwifruit cultivar, ‘Hort16A’, which is highly susceptible to

Vegetative incompatibility and potential involvement of a mycovirus in the Italian population of Geosmithia morbida [PDF]

, 2015
Studies carried out during an Italian outbreak of the Thousand Cankers Disease of walnut, demonstrated that non-coalescing cankers on host plants, separated by equidistant uninfected zones, were associated with incompatible strains of Geosmithia morbida.

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 ...

Effect of Botryosphaeria Stem Canker Disease on the Anatomical Structure of Eucalyptus Wood

Forest Science and Technology
Eucalyptus clones have been widely planted in Uganda to cope with the increasing demand for wood. However, the newly introduced clones are susceptible to attack by Botryosphaeria canker disease. Canker diseases have been reported to affect wood formation

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.

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.

Single and dual RPA‐CRISPR/Cas assays for point‐of‐need detection of Stewart's wilt pathogen (Pantoea stewartii subsp. stewartii) of corn and Maize dwarf mosaic virus

Pest Management Science, Volume 81, Issue 4, Page 1988-1999, April 2025.
Schematic diagram of the single and dual RPA‐CRISPR/Cas12a/13a diagnostic assays for the detection of Pantoea stewartii subsp. stewartii and Maize dwarf mosaic virus. The validated assays provide a useful and sensitive molecular tool for detecting two quarantine pathogens of maize within a minimal resource framework suitable for fast‐tracking the ...

Susceptibility to Apple Scab, Nectria Cancer and Powdery Mildew of Different Unsprayed Apple Varieties [PDF]

, 2004
Twentyfive apple varieties were evaluated for Apple scab (Venturia inaqualis), Nectria canker (Nectria galligena) and Powdery mildew (Podosphaera leucotricha) for 4 to 7 years. The trees were grown unsprayed.

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

Pest 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.
