Suppression of pine pitch canker disease and promotion of seedling growth in Japanese red pine using a newly isolated strain of Bacillus subtilis

Biological Control
Fusarium circinatum, the causal agent of pine pitch canker, can cause large-scale tree mortality in pine forests. Asymptomatic seedlings infected with F. circinatum can spread the disease at planting sites, highlighting the need for nursery-level control

Silent invaders: the hidden threat of asymptomatic phytobiomes to forest biosecurity. [PDF]

New Phytol
Summary Populations of diverse, unknown, and potentially pathogenic fungi and fungus‐like organisms are continuously introduced into new locations via asymptomatic infections (e.g. as endophytes or latent pathogens) within internationally traded live plants.

Extracting Protoplasts from Filamentous Fungi Using Extralyse, An Enzyme Used in the Wine Industry. [PDF]

Curr Protoc
Abstract The ability to extract protoplasts has contributed significantly to the study of fungi and plants. Protoplasts have historically been used to determine chromosome number via pulsed‐field electrophoresis and for the functional characterization of genes via protoplast transformation.

Pest categorisation of <i>Pestalotiopsis disseminata</i>. [PDF]

EFSA J, 2023
Abstract Following the commodity risk assessments of bonsai plants from China consisting of Pinus parviflora grafted on P. thunbergii performed by EFSA, the EFSA Plant Health Panel performed a pest categorisation of Pestalotiopsis disseminata, a clearly defined plant pathogenic fungus of the family Pestalotiopsidaceae. The pathogen has been reported on

Commodity risk assessment of debarked conifer wood chips fumigated with sulfuryl fluoride from the US. [PDF]

EFSA J
Abstract The European Commission requested the EFSA Panel on Plant Health to deliver a risk assessment on the likelihood of pest freedom from regulated EU quarantine pests, with emphasis on Bursaphelenchus xylophilus and its vectors Monochamus spp. of debarked conifer wood chips fumigated with sulfuryl fluoride as proposed by the United States (US) and

Impact of Seed Transmission on the Infection and Development of Pitch Canker Disease in Pinus radiata [PDF]

Forests, 2015
The aim of this study was to determine the impact of seed inoculum on subsequent disease development in nurseries, specifically studying incidence of seed infection, transmission rate of seed to seedlings, and rate of disease development from the primary inoculum source. Transmission rate of Fusarium circinatum (F. circinatum) from symptomatic trees of

Pitch canker kills pines, spreads to new species and regions

California Agriculture, 1994
The host and geographic range of the pitch canker pathogen has greatly increased since it was first discovered in California in 1986. Most significantly, it now affects many pine species, including native stands of Monterey pine, and has made a ...

Real-time loop-mediated isothermal amplification assay for rapid detection of Fusarium circinatum

BioTechniques, 2020
Fusarium circinatum is the causal agent of pitch canker, a lethal disease of pine and other conifers. Since F. circinatum is a quarantine organism, its timely detection could efficiently prevent its introduction into new areas or facilitate spread ...

Positive association between emerald ash borer residence time and accumulation of invasive plants

Ecosphere, Volume 14, Issue 12, December 2023., 2023
Abstract Invasive forest pests can affect the composition and physical structure of forest canopies that may facilitate invasion by non‐native plants. However, it remains unclear whether this process is generalizable across invasive plant species at broad spatial scales, and how other landscape characteristics may simultaneously facilitate non‐native ...
