“…Cropping strategies that could be applied to control mycotoxigenic fungi range from establishing a disease‐suppressive environment by applying soil solarization and agronomic practices like intercropping, mixed cropping, and crop rotation to using pathogen‐free seeds, field sanitation by removal of plant debris, and cultivation of resistant cultivars and seed treatments with biocontrol agents (Desai et al., 2020). However, a recent study on mycotoxin hazard analysis revealed land preparation (tillage, crop rotation, and cover cropping), planting and intercropping, application of botanical extracts, and fungal biocontrol agents as the most important preharvest practices that can influence/control mycotoxin production (Hamad et al., 2023; Nada et al., 2022).…”

Climate change (CC) is a complex phenomenon that has the potential to significantly alter marine, terrestrial, and freshwater ecosystems worldwide. Global warming of 2°C is expected to be exceeded during the 21st century, and the frequency of extreme weather events, including floods, storms, droughts, extreme temperatures, and wildfires, has intensified globally over recent decades, differently affecting areas of the world. How CC may impact multiple food safety hazards is increasingly evident, with mycotoxin contamination in particular gaining in prominence. Research focusing on CC effects on mycotoxin contamination in edible crops has developed considerably throughout the years. Therefore, we conducted a comprehensive literature search to collect available studies in the scientific literature published between 2000 and 2023. The selected papers highlighted how warmer temperatures are enabling the migration, introduction, and mounting abundance of thermophilic and thermotolerant fungal species, including those producing mycotoxins. Certain mycotoxigenic fungal species, such as Aspergillus flavus and Fusarium graminearum, are expected to readily acclimatize to new conditions and could become more aggressive pathogens. Furthermore, abiotic stress factors resulting from CC are expected to weaken the resistance of host crops, rendering them more vulnerable to fungal disease outbreaks. Changed interactions of mycotoxigenic fungi are likewise expected, with the effect of influencing the prevalence and co‐occurrence of mycotoxins in the future. Looking ahead, future research should focus on improving predictive modeling, expanding research into different pathosystems, and facilitating the application of effective strategies to mitigate the impact of CC.

“…Regarding further frequently detected Fusarium species in our study, F. equiseti is mainly known as a saprophytic species, which can also be a causal agent for FHB, but not as aggressive as F. graminearum or F. culmorum (Langseth et al 1999 ). Desai et al ( 2020 ) suggested that high intense rainfall events could promote the saprophytic living Fusarium species. In the present study, this species was more frequent detected on wheat kernels of the non-irrigated field side.…”

Infected grasses as inoculum for Fusarium infestation and mycotoxin accumulation in wheat with and without irrigation

Grasses growing next to agricultural fields influence the Fusarium abundance, the species composition, and the mycotoxin accumulation of wheat plants, especially the field parts directly adjacent to grasses, are highly affected. Grasses are a more attractive and suitable habitat for Fusarium fungi compared to other arable weeds and occur at mostly every semi-natural landscape element (e.g., kettle holes, hedgerows, field-to-field-borders). In our study, we analyzed the ability of a highly Fusarium infected grass stripe (F. graminearum, F. culmorum, F. sporotrichioides) to infect an adjacent wheat field with these species. Results show that the primary inoculated Fusarium species were as well the dominant species isolated from the wheat field. Regarding transects originating from the grass stripe going into the field, the results demonstrate that wheat ears next to the infected grass stripe have a higher Fusarium abundance and furthermore show higher mycotoxin accumulation in the wheat kernels. This effect was highly promoted by irrigation. Therefore, grass stripes next to arable fields must be considered as reservoirs for fungal infections and as a source for a contamination with mycotoxins.

“…This is especially important as it not only reduces yields but also directly affects human and animal health. In the context of climate change in Europe, food mycotoxins and pesticide residues are important food safety issues (Desai et al, 2020). This section examines the impact of projected climate change on FHB and its potential impact on components of the grain value chain, including production, processing and marketing.…”

Climate change badly effect the farming community which will lead to breakdown of the backbone of sustainable agriculture. Furthermore, the risk will play a major role when it comes to agricultural production in most countries and leads to lack specific strategies to overcome such situation. Furthermore, in most regions of the world there is a lack of research to understand the factors shaping farmer adaptation to climate change and the institutional links between farmer resilience. This study looked at climate change and its impact on global grain production. The results show that most farmers implementing climate change adaptation strategies are strongly linked with their inherited knowledge. Mostly it was affected to peasant farmers with low income. How will climate change impact the world’s food supply and how will its impacts be distributed? Increased or decreased food security risks? Findings suggest that agricultural advisor services are keeping them in the industry, introducing new forestry programs to capture carbon and ultimately reducing urbanization processes suggest that it is necessary to increase grain production.
