Heritage grapevines as sources of biological control agents for Botryosphaeria dieback pathogens

Phytopathologia Mediterranea, 2023
Grapevine trunk diseases cause severe damage in grapevines. Management strategies focus on protection of grapevine pruning wounds using chemical fungicides or biological control agents.

Lipophilic phytotoxins produced by Neofusicoccum parvum, a grapevine canker agent

Phytopathologia Mediterranea, 2010
Lipophilic phytotoxins produced by Neofusicoccum parvum, a Botryosphaeriaceae species pathogenic to grapevine, were isolated and identified by spectroscopic methods as (3R,4R)-(-)-4-hydroxymellein, (3R,4S)-(-)-4-hydroxymellein, isosclerone and tyrosol ...

Lasiodiplodia mitidjana sp. nov. and other Botryosphaeriaceae species causing branch canker and dieback of Citrus sinensis in Algeria.

PLoS ONE, 2020
Several Botryosphaeriaceae species are known to occur worldwide, causing dieback, canker and fruit rot on various hosts. Surveys conducted in ten commercial citrus orchards in the northern region of Algeria revealed five species of Botryosphaeriaceae ...

Fungal Pathogens Associated with Aerial Symptoms of Avocado (Persea americana Mill.) in Tenerife (Canary Islands, Spain) Focused on Species of the Family Botryosphaeriaceae

Microorganisms, 2023
Fungi of the family Botryosphaeriaceae are considered responsible for various symptoms in avocado such as dieback, external necrosis of branches and inflorescences, cankers on branches and trunks, or stem-end rot of fruits.

Neofusicoccum and Phytophthora Species: An Emerging Threat to Fig Trees (Ficus carica) in Italy, With the Description of Phytophthora messapica sp. nov.

Plant Pathology, Volume 75, Issue 3, May–June 2026.
The work helped clarify the complex aetiology of common fig decline in Italy as the result of a simultaneous attack by canopy pathogens (Ascomycetes, family Botryosphaeriaceae) and root pathogens (oomycetes of the genus Phytophthora) and led to the discovery of several new host–pathogen associations and a new Phytophthora species.

Fungal Pathogen Activity and Stress‐Dependent Responses of Grapevine Wood to Esca and Drought

Physiologia Plantarum, Volume 178, Issue 3, May/June 2026.
ABSTRACT Biotic and abiotic stresses alter the physiology of perennial plants, with consequences for fungal endophytes and disease expression. In grapevine, drought inhibits esca disease expression, but the underlying molecular interactions between the plant and fungi are unknown. We combined wood metatranscriptomics, metabolomics, and metabarcoding to

Pathogenicity of Botryosphaeriaceae and Phytophthora species associated with Paulownia dieback, canker and root rot in Italy

Phytopathologia Mediterranea, 2023
In recent years, an unusual decline and mortality has been observed in Paulownia plantations throughout the Marche region (Central Italy). Given the economic importance of this emerging forest crop, a study was conducted to determine which pathogens are ...

Fungal Species of Botryosphaeriaceae Associated With Avocado Dieback in Southern Spain

Plant Pathology, Volume 75, Issue 1, January/February 2026.
In southern Spain, water scarcity has favoured avocado diseases, causing branch dieback, mummified fruits and cankers. Between 2019 and 2022, 252 fungi were isolated; the most common were Neofusicoccum spp. and Lasiodiplodia sp. Their pathogenic role was confirmed, with Botryosphaeriaceae identified as the main cause of avocado dieback.

A Survey of Trunk Disease Pathogens within Citrus Trees in Iran

Plants, 2020
Citrus trees with cankers and dieback symptoms were observed in Bushehr (Bushehr province, Iran). Isolations were made from diseased cankers and branches. Recovered fungal isolates were identified using cultural and morphological characteristics, as well
