Special Issue Information

Dear Colleagues,

Climate change (CC) poses a significant threat to global food production and safety. Crops are particularly vulnerable to this phenomenon, with multiple projections indicating an increased burden of plant diseases under CC scenarios. Shifts in fungal community composition, diversity, and pathogenicity represent critical challenges in the coming decades. Changes in global mean temperature, altered precipitation patterns, and the frequency of extreme weather events can profoundly influence plant–pathogen interactions, ultimately compromising grain yield and quality. Moreover, understanding how environmental factors such as elevated CO2 levels, temperature fluctuations, and relative humidity—as well as abiotic stresses including drought, heatwaves, and waterlogging—modulate plant–pathogen dynamics is of paramount importance.

This Special Issue, "Fusarium in Crops Under Climate Change Scenarios", aims at showcasing cutting-edge research on the impact of climate change on Fusarium species. We welcome contributions addressing Fusarium diversity, pathogenicity, interactions with other fungal genera, and shifts in plant–host relationships affecting grain yield and quality. Further topics of interest include the implications for by-products, mycotoxin contamination, and potential mitigation strategies. We invite the submission of review articles, original research papers, and short communications.

Malt bagasse is the primary solid waste product from the brewing process, with notable environmental implications. Due to its nutritional value, it has potential as animal feed, primarily through ensilage. Alfalfa pellets can enhance this silage by adding digestible nitrogen and fibre. However, the high moisture content favours microbial contamination, particularly by fungi like Fusarium, which produces harmful mycotoxins. This study evaluated the impact of winter silage on fungal diversity, Fusarium presence, and mycotoxin contamination in malt bagasse, comparing the pre- and post-silage stages with the addition of alfalfa pellets. Results showed a diverse range of fungi, including Mucor, Cladosporium, Fusarium, and Penicillium, as well as yeasts. Fungal contamination was higher before silage, although the addition of alfalfa increased it after silage was produced. Fusarium verticillioides was the most common Fusarium species. Mycotoxin analysis detected DON (1.4 ppb) in only one sample. A two-month winter silage process under cold-temperate conditions appears to reduce fungal contamination and preserve feed quality. These findings support silage as a circular strategy to manage brewery waste safely, but further research and policy measures are needed to minimise biological risks in the brewing and livestock sectors amid climate change.
