Technical Abstract: Mycotoxin contamination of food and feed is among the top food safety concerns. Fusarium spp. cause serious diseases in cereal crops reducing yield and contaminating grain with mycotoxins that can be deleterious to human and animal health. Fusarium graminearum and Fusarium verticillioides infect wheat and maize and contaminate grain with trichothecenes and fumonisins, respectively. Soil amendment with biochar can confer multiple benefits to plants including increased productivity and enhanced disease resistance. The objective of this study was to test whether biochar could enhance wheat and maize resistance to F. graminearum and F. verticillioides and reduce mycotoxin contamination. Since biochar has also been shown to promote the growth of beneficial microorganisms in the rhizosphere, we further assessed the potential of biochar as a carrier system for the biocontrol agent Trichoderma harzianum which is known to be effective against several fungal soilborne plant pathogens. Results from greenhouse trials suggest that, depending on soil type, amendment with biochar can influence Fusarium disease development and mycotoxin accumulation.
