and , in addition to , may cause Phomopsis cane and leaf spot disease in grapevine.

Phomopsis cane and leaf spot (PCLS) disease, affecting grapevines ( and spp.), has been historically associated with . Typical disease symptoms, comprising bleaching and black pycnidia, have also been associated with other spp.

A Bayesian model for control strategy selection against infections.

Plant pathogens pose a persistent threat to grape production, causing significant economic losses if disease management strategies are not carefully planned and implemented. Simulation models are one approach to address this challenge because they provide short-term and field-scale disease prediction by incorporating the biological mechanisms of the disease process and the different phenological stages of the vines. In this study, we developed a Bayesian model to predict the probability of infection in grapevines, considering various disease management approaches.

First Description of Non-Enzymatic Radical-Generating Mechanisms Adopted by : An Unexplored Pathway of the White Rot Agent of the Esca Complex of Diseases.

() is the primary Basidiomycota species causing white rot in European vineyards affected by the Esca complex of diseases (ECD). In the last few years, an increasing number of studies have highlighted the importance of reconsidering the role of in ECD etiology, justifying an increase in research interest related to 's biomolecular pathogenetic mechanisms. In the context of the current re-evaluation of the binary distinction (brown vs.

Tannins-lignin mixed nanoformulations for improving the potential of neem oil as fungicide agent.

Sustainability and circular economy are increasingly pushing for the search of natural materials to foster antiparasitic treatments, especially in the case of economically relevant agricultural cultivations, such as grapevine. In this work, we propose to deliver neem oil, a natural biopesticide loaded into novel nanovectors (nanocapsules) which were fabricated using a scalable procedure starting from Kraft lignin and grapeseed tannins. The obtained formulations were characterized in terms of size and Zeta potential, showing that almost all the nanocapsules had size in the suitable range for delivery purposes (mean diameter 150-300 nm), with low polydispersity and sufficient stability to ensure long shelf life.

Xylem anatomy and hydraulic traits in grafted cuttings in view of their impact on the young grapevine decline.

Grapevine grafting is an essential practice in viticulture and over the years, various bench grafting techniques have been developed to mechanize the nursery process and to increase the yield in number of viable cuttings. Bench grafting is a fundamental nursery practice that can potentially affect the quality of propagation material also in young decline associated to grapevine trunk diseases and has been recently reported to influence leaf symptoms development associated with diseases of Esca complex. The study aimed to investigate how three bench grafting methods [i.
