A Field Survey of Grapevine Germplasm Susceptible to Eutypa Dieback

HortScience
Eutypa dieback of grapevine is a trunk disease that impacts vineyard productivity worldwide. Grape germplasm is typically evaluated for resistance to Eutypa dieback through controlled inoculations in the greenhouse, although the high level of replication

Short-term Effects of Remedial Surgery to Restore Productivity to Eutypa lata Infected Vines

Phytopathologia Mediterranea, 2004
Eutypa dieback, caused by the wood infecting fungus Eutypa lata, causes a gradual decline in vineyard production. Many growers renew infected vines by removing infected wood.

Arthropods as Vectors of Grapevine Trunk Disease Pathogens: Quantification of Phaeomoniella chlamydospora on Arthropods and Mycobiome Analysis of Earwig Exoskeletons [PDF]

Journal of Fungi
Viticulture worldwide is challenged by grapevine trunk diseases (GTDs). Involvement of arthropods in the dissemination process of GTD pathogens, notably esca pathogens, is indicated after detection of associated pathogens on arthropod exoskeletons, and ...

High-Resolution Melting assays development for discrimination of fungal pathogens causing Grapevine Trunk Diseases. [PDF]

PLoS ONE
Grapevine Trunk Diseases are a set of fungal diseases that mainly affect wood tissues of grapevine, reducing plant fitness and yield. These diseases limit grape production, so producers need to employ several management strategies to avoid great losses ...

Population genomics of the grapevine pathogen Eutypa lata reveals evidence for population expansion and intraspecific differences in secondary metabolite gene clusters. [PDF]

PLoS Genetics, 2022
Eutypa dieback of grapevine is an important disease caused by the generalist Ascomycete fungus Eutypa lata. Despite the relevance of this species to the global wine industry, its genomic diversity remains unknown, with only a single publicly available ...

Silver-selenium nanoparticles and selected chemical compounds significantly inhibit grapevine trunk disease pathogens. [PDF]

Pest Manag Sci
A 2‐year in planta study confirmed antifungal activity of selected chemicals against GTD pathogens. Silver‐selenium nanoparticles inhibited D. eres and E. lata, but not D. seriata. Despite limited spectrum, they show promise as alternatives for targeted GTD control, with no phytotoxic effects observed.

Fungal Pathogen Activity and Stress-Dependent Responses of Grapevine Wood to Esca and Drought. [PDF]

Physiol Plant
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

Adverse effects of grapevine trunk diseases on canes produced from infected rootstock mother blocks. [PDF]

Pest Manag Sci
High incidences of GTD pathogens in rootstock mother vine heads, with Phaeomoniella chlamydospora and Diplodia seriata affecting cane physiology and quality. One‐year‐old canes harbor systemic inoculum, highlighting the need for careful monitoring and management.
