Commodity risk assessment of oak and walnut logs from the US

EFSA Journal, Volume 24, Issue 1, January 2026.
Abstract The European Commission submitted to the EFSA Panel on Plant Health a Dossier from the United States proposing the use of a vacuum–steam–heat treatment as a stand‐alone phytosanitary measure to mitigate the risk of entry of Bretziella fagacearum, Geosmithia morbida and its vector Pityophthorus juglandis (thousand cankers disease complex) into ...

Nursery and field experiments to test conifers susceptibility to Pitch Canker disease

Journal of Agricultural Extension and Rural Development, 2012
Fusarium circinatum is the causal agent of the Pitch Canker disease, which was first detected in Spain in 2004. Not only Pinus species seedlings in nurseries were affected but also Pinus radiata plantations in the forest. Thus, the pathogen has spread out over several pine forests of northern Spain producing substantial economical losses. Consequently,

Two plasmid‐borne virulence genomic islands of Clavibacter michiganensis are genetically diverse and determine the development of wilt symptoms in host plants

New Phytologist, Volume 247, Issue 5, Page 2293-2311, September 2025.
Summary Plasmids contribute to the efficient adaptation of bacteria to specific niches in nature. The gram‐positive bacterium Clavibacter michiganensis carries two plasmid‐borne important virulence genes, celA and pat‐1, necessary for wilting in tomato. The 88 C.

Fostering regeneration: gap creation strategies in mature Monterey pine stands in coastal California

Frontiers in Forests and Global Change
Monterey pine, a regionally endemic species with the greatest abundance on the Monterey Peninsula in central coastal California, is the most widely planted conifer species worldwide. Many native Monterey pine forests in the wildland–urban interface (WUI)

Extracellular Vesicles Modulate Growth and Stress Adaptation in Fusarium circinatum

Plant Pathology, Volume 74, Issue 7, Page 2121-2136, September 2025.
Biofilm‐derived extracellular vesicles (bEVs) from Fusarium circinatum enhance conidia viability, biomass, matrix production and resistance to stress and antifungal agents. ABSTRACT The molecular mechanisms influencing Fusarium circinatum, an important pine tree pathogen, remain partially understood.

Surfactants Improve the Susceptibility of Five Landscape Pines to Pitch Canker Disease, Caused by Fusarium subglutinans f. sp. pini [PDF]

HortTechnology, 1999
Pitch canker, caused by Fusarium subglutinans f. sp. pini , causes branch die-back and stem cankers in many species of pine. Monterey pine ( Pinus radiata D. Don), one of the most widely planted pines in the world,

First Report of Fusarium circinatum, Causal Agent of Pitch Canker Disease, from the Roots of Mature Aleppo Pines in California [PDF]

Plant Health Progress, 2007
A rapid decline of Aleppo pines was observed in the parking lot of the Legoland amusement park in San Diego Co., CA. Although Aleppo pine is a known host for Fusarium circinatum, this is the first report describing resin-soaked sapwood lesions in the roots of mature trees. Previous reports on root infections regarded seedlings. The infestation in this

Spatial relationships between nitrogen status and pitch canker disease in slash pine planted adjacent to a poultry operation

Environmental Pollution, 2007
Pitch canker disease (Fusarium circinatum Nirenberg & O'Donnell) causes serious shoot dieback, reduced growth and mortality in pines found in the southern and western USA, and has been linked to nutrient imbalances. Poultry houses with forced-air ventilation systems produce nitrogen (N) emissions.

Molecular identification of Fusarium species in commercial vanilla and crop wild relatives in Colombia

Environmental Microbiology Reports, Volume 16, Issue 6, December 2024.
Fungal strains with affinity to both Fusarium oxysporum f. sp. vanillae (Fov) and F. oxysporum f. sp. radicis‐vanillae (Forv) were isolated from symptomatic and asymptomatic tissues of both commercial vanilla crops and crop wild relatives (CWR) in Colombia.
