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 ...

Statistical analysis of grapevine mortality associated with esca or Eutypa dieback foliar expression

Phytopathologia Mediterranea, 2012
Esca and Eutypa dieback are two major wood diseases of grapevine in France. Their widespread distribution in vineyards leads to vine decline and to a loss in productivity.

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.

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.

Assessment of canopy size using UAV-based point cloud analysis to detect the severity and spatial distribution of canopy decline

OENO One, 2021
This study aimed to validate the use of UAV-based point cloud analysis to detect canopy decline severity and its spatial distribution in vineyards. A new approach to assess canopy decline, caused by Eutypa dieback-like symptoms, using unmanned aerial ...

Assessing the relationship between cordon strangulation, dieback, and fungal trunk disease symptom expression in grapevine

OENO One, 2023
Grapevine cordons wrapped tightly around the cordon wire during establishment may be susceptible to an early occurrence of decay and dieback symptoms. A loss of productivity is often observed in older permanent cordons that have been constricted in this

Molecular Polymorphism and Phenotypic Diversity in the Eutypa Dieback PathogenEutypa lata [PDF]

Phytopathology®, 2015
Pathogen adaptation to different hosts can lead to specialization and, when coupled with reproductive isolation, genome-wide differentiation and ecological speciation. We tested the hypothesis of host specialization among California populations of Eutypa lata (causal fungus of Eutypa dieback of grapevine and apricot), which is reported from >90 ...

A Reassessment of the Species Concept inEutypa lata, the Causal Agent of Eutypa Dieback of Grapevine [PDF]

Phytopathology®, 2006
Eutypa dieback is a vascular disease of several cultivated crops and trees worldwide. The attribution of the name to the agent responsible for branch dieback is ambiguous. Pathogenicity of Eutypa sp. first was reported on apricot and the causal agent was named E. armeniacae.
