Previous surveys conducted in commercial nurseries found that different wood fungi, namely Cylindrocarpon spp., Botryosphaeriaceae, Phomopsis viticola and Phaeomoniella chlamydospora infect grapevine cuttings. Two fi eld trials were carried out to evaluate the effectiveness of cyprodinil + fl udioxonil, pyraclostrobin + metiram, fl udioxonil and cyprodinil to prevent or reduce natural infection...

Petri disease is a problem for vineyard caused mainly by the fungus Phaeomoniella chlamydospora. Contaminated seedlings are source of inoculum disease. Treatment to disinfect vine rootstock cuttings seedling production hot water treatment (HWT) 50 °C 30 min, but efficiency contested. To improve its efficacy, study aimed assess combination following methods and reason control: i) exposition five...

Fungi that cause grapevine trunk diseases, including Diplodia seriata, Eutypa lata, Neofusicoccum parvum, and Phaeomoniella chlamydospora, all colonize woody tissues, but lesions develop to different extents. Such variation is thought correspond fungal virulence, it may also reflect host metabolic responses limit colonization. From the stems of potted Vitis vinifera ‘Cabernet-Sauvignon’ in gree...

Grapevine is one of the most cultivated fruit crop worldwide with Vitis vinifera being the species with the highest economical importance. Being highly susceptible to fungal pathogens and increasingly affected by environmental factors, it has become an important agricultural research area, where gene expression analysis plays a fundamental role. Quantitative reverse transcription polymerase cha...

Petri disease causes decline of grapevines worldwide. The grapevine endophyte Phaeomoniella chlamydospora is the most important fungal pathogen associated with this disease. Epidemiological studies of this pathogen have been hampered by its common occurrence in the internal tissue of apparently healthy vines. Development of a molecular marker for a single strain would overcome this limitation a...

The grapevine trunk diseases (GTD) Botryosphaeria dieback and esca threaten the sustainability of industry worldwide. This study aimed to evaluate compare efficacy various liquid (pyraclostrobin + boscalid thiophanate methyl) paste (paste tebuconazole) formulation fungicide treatments as well biological control agents (Trichoderma atroviride SC1 T. I-1237), for their potential prevent infection...

Up to 60 species of fungi in the Botryosphaeriaceae family, genera Cadophora, Cryptovalsa, Cylindrocarpon, Diatrype, Diatrypella, Eutypa, Eutypella, Fomitiporella, Fomitiporia, Inocutis, Phaeoacremonium and Phaeomoniella have been isolated from decline-affected grapevines all around the World. The main grapevine trunk diseases of mature vines are Eutypa dieback, the esca complex and cankers cau...
