Summary: Black foot disease is a significant grapevine root disease worldwide, particularly in New Zealand. This study found that arbuscular mycorrhizal fungi (AMF) can reduce infection and mitigate the effects of black foot disease on grapevine rootstocks. Unlike previous research focused on only a few AMF species, this study used entire AMF communities found in rootstocks from New Zealand vineyards. The results showed that AMF treatments decreased disease incidence and severity, and increased vine growth parameters.

Summary: The results of the experiment showed that different treatments of Trichoderma significantly reduced black foot infections in the rootstock bases of the vines in only one season. The colonization of Trichoderma was significantly higher in the base and collar roots compared to the middle and root tip parts, with significantly less BFD pathogens isolated from the base than the roots. The dipping of basal ends in the dry formulation followed by monthly soil drenches consistently gave higher colonization, while the 1-hour soak of the bases of vines was not effective.

Summary: This study confirmed the presence of Dactylonectria macrodidyma as the causal agent of olive root rot in Iraq. The infected seedlings showed necrotic lesions on roots, chlorosis and necrosis of leaf margins, and curling leaf lamina, leading to significant reductions in plant growth.

Summary: This study investigated the prevalence and pathogenicity of black-foot pathogens in grapevine nurseries in Turkey. The results showed that these pathogens were highly prevalent in asymptomatic grapevines and posed a serious threat to Turkish viticulture.

Summary: Colonies resembling Nigrospora were found in sweet potato plants affected by foot rot disease in Lagoa dos Gatos, Brazil. Inoculation of these isolates in sweet potato tubers resulted in similar symptoms, with brown lesions turning black and yellowing of leaves. Morphological and phylogenetic analyses confirmed the presence of Nigrospora vesicularifera, marking its first identification in sweet potato and its first record as a pathogen in Brazil.

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: Black root rot (BRR) is a significant disease affecting cotton and other crops, particularly in cooler regions with short growing seasons. Resistance to BRR has been identified in G. arboreum accession BM13H, which is associated with reduced hyphal growth and sporulation. Transcriptome analysis revealed that BM13H responds to infection at early time points, with few differentially expressed genes observed by day 5. Inheritance studies indicated a single semi-dominant locus conferring resistance to BRR in BM13H, which was fine mapped to a region on chromosome 1 containing potential resistance genes.

Summary: In October 2017, yellow and wilted leaves as well as partially rotted roots were observed in ginseng plants in Jilin Province, China. Molecular analysis confirmed that Fusarium subglutinans obtained from the rotting tissues of ginseng roots was responsible for causing the root rot. Pathogenicity analysis further supported the findings by showing that inoculation of ginseng with these isolates resulted in identical symptoms.

Summary: The resurgence of interest in cannabis cultivation has brought new challenges, including difficult-to-control pests and pathogens infecting cannabis plants. Early detection of plant pathogens using molecular techniques such as DNA sequencing is essential for disease control. This study reported the first fungal plant pathogen, Berkeleyomyces rouxiae, causing black root rot in high THC-containing cannabis, and also presented the first whole genome sequence of B. rouxiae, which will aid in the development of sequence-based diagnostics and comparative genomics for this globally important plant pathogen.

Summary: Anthracnose is the most important disease affecting the value of olive oil. This study compared the effects of different olive anthracnose pathogens on the oil extracted from two popular Portuguese olive cultivars, finding that 'Galega Vulgar' was more susceptible to the disease. The quality of virgin olive oil was significantly impacted by the presence of Colletotrichum species in the fruits, with varying levels of acidity, fatty acid ethyl esters, and total phenols.

Summary: Esca is a major grapevine trunk disease that affects vineyards in the Northern hemisphere, with disputed etiology and epidemiology due to various internal and external symptoms and wood pathogens. While the role of pathogenic fungi in wood symptoms is well assessed, their impact on leaf symptoms remains uncertain. Recent studies focus on the microbiological aspect of esca, particularly the involvement of Hymenochaetales, in vineyards. The presence of Hymenochaetales and tracheomycotic fungi is believed to be a prerequisite for leaf symptoms, but further investigation is needed to understand their relationship with grapevines and other factors.

Summary: This study assessed the biological activity of essential oils from four Juniperus species obtained through different distillation methods. The results show that plant sex can affect the composition and content of the oils, leading to differences in bioactivity. All tested oils demonstrated significant repellent and insecticidal activity against aphids.

Summary: The bi-cistronic virus cherry virus Trakiya, detected recently, is related to unclassified viruses with arthropod vectors/hosts. The virus was successfully transmitted between Prunus trees, and symptoms observed in the field were similar to experimental infection symptoms. The virus was also mechanically transmitted to various plant species, and survey analysis showed a high infection rate in cherry trees.
