Bacteria in a woody fungal disease: characterization of bacterial communities in wood tissues of esca-foliar symptomatic and asymptomatic grapevines

Frontiers in Microbiology, 2015
Esca is a grapevine trunk disease (GTD) associated with different pathogenic fungi inhabiting the woody tissues. Bacteria can also be found in such tissues and they may interact with these fungal colonizers.

Vegetal residue‐based formulation of Trichoderma ossianense, a new indigenous vineyard species adapted to alkaline pH with potential biocontrol ability against Black‐foot disease pathogens

Pest Management Science, EarlyView.
The study identifies Trichoderma ossianense, was can be isolated from grapevine roots, is capable of growing at alkaline pH and controls black‐foot pathogens, highlighting the vegetal residue‐based formulations that preserve its viability. Abstract BACKGROUND Fungi of the Trichoderma genus are used in vineyards as biological control agents mainly ...

Neofusicoccum parvum Associated with Grapevine Trunk Diseases in Chile

Plant Disease, 2011
During 2009 and 2010, a survey (n = 520) of diseased grapevines (Vitis vinifera L.) was done in vineyards located in Maipo and Colchagua valleys (33°43′ to 34°36′S) in Chile. Symptoms of trunk diseases (TD) were observed on >10-year-old grapevines and consisted of short internodes, dead spurs and arms, and dieback.

Terahertz Study of Wood Structure as Impacted by Grapevine Trunk Diseases [PDF]

2019 44th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz), 2019
Grapevine trunk diseases affect grapevines worldwide and dramatically shorten the longevity of vineyards. This study has successfully demonstrated the use of THz time-domain imaging to identify the grapevine wood tissues degraded by the fungi responsible for grapevine trunk diseases.

Current status of grapevine trunk disease pathogens on asymptomatic nursery-produced grapevines in Türkiye

Phytopathologia Mediterranea, 2023
Good health of grapevine plants is important for productivity and sustainability of newly established vineyards, and accurate detection of bacterial and fungal pathogens is a prerequisite for managing the diseases they cause in nurseries. This study screened marketable, bare-rooted grapevine plants, obtained from different geographical regions of ...

Efficacy evaluation of pneumatic solid set canopy delivery system to control powdery mildew (Erysiphe necator) in Washington vineyards

Pest Management Science, EarlyView.
The findings of this study indicate that powdery mildew control achieved with the pneumatic solid set canopy delivery system (PSD‐SSCDS) was comparable with that of a conventional airblast sprayer. These results highlight the PSD‐SSCDS as a promising alternative spray technology. Abstract BACKGROUND In this study, a previously optimized pneumatic spray
