Special Issue Information

Dear Colleagues,

Fungal diseases in crops represent a significant and persistent threat to global agricultural systems, impacting food security, economic stability, and ecosystem health. This Special Issue of the Journal of Fungi focuses on advancing our understanding of fungal pathogens, their interactions with host plants, and the development of sustainable management strategies.

Contributions to this Special Issue will explore the molecular mechanisms underpinning fungal pathogenicity, host resistance, and the complex dynamics within the plant-microbe-environment nexus. Cutting-edge research on the epidemiology of fungal diseases, innovative diagnostic tools, and the implications of climate change on disease prevalence and severity will be highlighted.

Emphasis will also be placed on integrated disease management approaches, including the use of biocontrol agents, resistant crop varieties, and novel antifungal compounds. This Special Issue aims to bridge fundamental research and practical applications, offering insights into mitigating the burden of fungal diseases while promoting sustainable agricultural practices.

For this Special Issue, we welcome original research articles, comprehensive reviews, and case studies from diverse disciplines, fostering collaboration among plant pathologists, mycologists, agronomists, and environmental scientists. By addressing the global challenges posed by fungal crop diseases, this Special Issue aspires to inspire innovative solutions for the agricultural systems of the future.

Mycogone perniciosa is the causative agent of wet bubble disease, which induces significant losses in the production of Agaricus bisporus, indicating the high importance of the development of novel inhibitory agents. The isolation, identification, and molecular characterization of five isolates of M. perniciosa from diseased fruit bodies of A. bisporus was done. Moreover, the study evaluated the in vitro and in situ potential of Origanum vulgare essential oil (EO) to limit M. perniciosa growth and provided chemical characterization of its volatile components. The obtained strains differed phenotypically and according to their molecular characteristics. O. vulgare EO has shown more promising antifungal activity than the commercial fungicide Prochloraz-Mn in the microatmospheric method. In the treatment of experimentally induced wet bubble disease on A. bisporus in the growing chambers with 2% of O. vulgare EO and simultaneous application of spore suspension of mycopathogen, O. vulgare EO totally inhibited the growth of M. perniciosa. Carvacrol, p-cymene, γ-terpinene, and thymol were dominant constituents of O. vulgare EO examined in this study. O. vulgare EO has shown promising potential to limit growth of M. perniciosa and should be further explored as a novel biofungicide. Full article

Apple scab, caused by Venturia inaequalis, remains a major challenge for apple production in Morocco, where disease management heavily depends on fungicide applications. However, increasing reports of resistance have raised concerns about the long-term efficacy of commonly used products and the economic sustainability of apple orchards. In this study, we evaluated the sensitivity of five V. inaequalis isolates from the Fes-Meknes region, a key apple-producing area in Morocco, to three fungicides: difenoconazole, trifloxystrobin, and thiophanate-methyl. The identity of the isolates was confirmed based on both morphological characteristics and by molecular analysis of the ITS region. In vitro and in vivo assays revealed significant differences in isolate responses. Difenoconazole consistently showed the highest efficacy, with EC50 values ranging from 0.05 to 1.46 µg/mL, and preventive applications reducing disease severity by up to 85.8% at 10 µg/mL. In contrast, trifloxystrobin and thiophanate-methyl exhibited much higher EC50 values (2.94–29.62 µg/mL and 14.84–1237.20 µg/mL, respectively), indicating widespread resistance, particularly to thiophanate-methyl, whose curative and preventive efficacy rarely exceeded 44%. Preventive treatments were significantly more effective than curative applications for all fungicides tested. These findings highlight the urgent need to revise apple scab management strategies in Morocco, including the rotation of fungicides with different modes of action and the integration of non-chemical approaches. Broader sensitivity monitoring and the use of molecular diagnostics are recommended to better inform sustainable disease control programs. Full article
