Summary: This study aimed to identify tolerant grapevine cultivars to GTD fungi based on external symptoms observed in the vineyard and to characterize the pathogenic mycoflora associated with symptomatic vines. Results showed that some grapevine cultivars displayed high susceptibility to GTDs while others were considered tolerant. The prevalent fungal species isolated from symptomatic vines were Phaeomoniella chlamydospora, Cryptovalsa ampelina, and Dothiorella sarmentorum.

Summary: This review analyzes the current state of identification and detection of grapevine trunk diseases (GTDs) and emphasizes the urgent need for the development of new technologies. The current methods and protocols are relatively limited and further exploration and research are needed. New detection methods and practices will better control the spread of pathogens and improve vineyard management.

Summary: Grapevine trunk diseases (GTDs) are complex and challenging to identify and eradicate. This study investigated the fungal community structure associated with GTDs symptomatic and asymptomatic grapevines. The results showed that symptomatic plants had a lower abundance but higher diversity of GTDs-associated fungi. The composition of fungal endophytic communities was significantly different according to the symptomatology and not affected by the cultivar.

Summary: The study revealed that grapevine trunk disease symptomatic plants support a wood fungal microbiome, showing cultivar and biogeography-dependent patterns that can be used as a proxy to distinguish between healthy and diseased vines. Furthermore, it highlighted strong interactions between the bacterial and fungal wood microbiome in asymptomatic vines.

Summary: This study identified several Trichoderma species from grapevines in British Columbia and evaluated their biocontrol activity against BD fungi. The results showed that these isolates were able to significantly inhibit the growth of fungal pathogens and provide protection for pruning wounds for up to 21 days. They also exhibited similar or better control compared to commercial products.

Summary: Grapevine trunk diseases are a major threat to grape cultivation worldwide. This study in China identified five fungal species associated with black foot disease, with D. macrodidyma being the most aggressive. This new knowledge will help in developing effective control measures for this destructive disease.

Summary: In this study, a large number of bacteria with inhibitory effects on grapevine trunk diseases were isolated from commercial vineyards in California. These bacteria were identified as Bacillus velezensis, Pseudomonas spp., and Serratia plymuthica, and they showed inhibition against various fungal pathogens in vitro. The results suggest that these bacteria may serve as potential biocontrol agents against grapevine trunk diseases.

Summary: Romania has a long history of grapevine culturing and winemaking, but viticulture faces devastating biological threats from grapevine trunk diseases (GTDs) and grape spoilage. Many countries, including Romania, have shifted towards sustainable biocontrol strategies to replace toxic chemical inputs. B. velezensis strains show strong antifungal activity against grape and grapevine fungal pathogens, making them suitable for grapevine biologic control.

Summary: This study investigated the diversity of fungal species in grapevine trunk disease samples in China and discovered several species that were reported for the first time in China and worldwide on grapevine. The results provide important insights for further understanding the interactions among fungal communities and strategies for managing grapevine trunk diseases.

Summary: Grapevine trunk diseases (GTDs) cause significant economic losses in wine-producing countries. Researchers conducted nursery experiments using Trichoderma atroviride (Ta) SC1 and Bacillus subtilis (Bs) PTA-271, alone and in combination, to study their biocontrol effect on GTD pathogens. The results showed that these biological treatments reduced the infection rate and fungal isolation of GTD pathogens in grapevine nursery material.

Summary: The effectiveness of some biocontrol agents in reducing the incidence and severity of black-foot and Petri diseases varied depending on the plant part analyzed and the plant age. Combining multiple beneficial microbes in a biocontrol preparation is necessary to prevent infection by these fungi in vineyards.

Summary: Canker and severe dieback symptoms were observed on barberry trees in Fars Province, Iran in 2016. Wood samples were collected from infected barberry trees and 15 fungal species were identified, including Lasiodiplodia theobromae, which was found to be the most aggressive species. This study highlights the importance of considering barberry trees as alternative hosts for grapevine fungal trunk pathogens.

Summary: Grapevine trunk diseases (GTDs) have become a concern in wine producing countries, including Romania. This study reviews the scientific information on GTDs in Romania and finds that there is limited literature available on the subject. Three out of six fungal GTDs are well documented in Romanian viticultural zones, with management measures focusing on prevention and removal of affected grapevines.

Summary: Grasslands are major primary producers and important components in watersheds. Various factors, such as fungal interactions, herbivores, and plant-fungal pathogenic interactions, play vital roles in maintaining biodiversity and biomass in grasslands. Decreased species diversity in grasslands can lead to increased severity and transmission rates of fungal diseases, highlighting the importance of understanding and managing ecological complexities in these ecosystems.
