An Artificial Inoculation Protocol for Greenhouse Resistance Screening of Loblolly Pine Seedlings Against Brown Spot Needle Blight

Forest Pathology, Volume 56, Issue 1, February 2026.
ABSTRACT Brown spot needle blight (BSNB), caused by the fungal pathogen Lecanosticta acicola, has been rapidly increasing in incidence and severity on loblolly pine (Pinus taeda), the most dominant and commercially important pine species in the southeastern United States.

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

Interaction Between Pinus Species and Foliar Fungal Pathogens: Similar Symptoms, Contrasting Physiology

Plant Pathology, Volume 75, Issue 1, January/February 2026.
Lecanosticta acicola and Dothistroma septosporum trigger similar symptoms; host responses diverge sharply: Pinus pinea mounts robust defences, P. pinaster remains vulnerable, and P. radiata sustains growth. These contrasting strategies highlight species‐specific resilience and provide key insights for sustainable forest protection.

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 ...

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.

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)

First Report of Pitch Canker on Pines Caused by Fusarium circinatum in Portugal

Plant Disease, 2009
In November of 2007, dieback symptoms (basal needle dieback, wilting, and dieback of terminal shoot) were observed on plant groups of Pinus radiata and P. pinaster in a tree nursery located in Anadia in the central region of Portugal (40°26′N, 08°23′W).

Pitch Canker Caused by Fusarium circinatum Identified on Spruce Pine in Alabama

Plant Disease, 2003
A dieback associated with resinous branch and main stem cankers was observed on two spruce pine (Pinus glabra Walt.) trees in Lee County, Alabama in July 2002. Xylem tissues beneath the cankers were resinsoaked as is characteristic of pitch canker on other southern pine species.

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.

Pre-Infection Behavior of the Pitch Canker Fungus Fusarium circinatum on Pine Stems [PDF]

The Plant Pathology Journal, 2008
Pre-infection behavior of Fusarium circinatum on stems of pine species was investigated with scanning electron microscopy. Two-year-old stems of Pinus densiflora and p. rigida were inoculated with the fungal conidial suspension and subjected to for up to 16 hr. Most microconidia germinated 12 hr after inoculation on pine stems.
