FUSAMN
Fusarium meridionale causes head blight, ear rot, stalk rot, and root rot in corn. It can produce mycotoxins. Where reported, it is often the most aggressive and prevalent Fusarium species. Transmission occurs primarily via infected crop residues and airborne spores, dispersed by wind, rain splash, or mechanical means. Although the pathogen has been isolated from kernels, no definitive evidence was found that the fungus transmits from seed to seedling.

Currently, there is no direct evidence confirming that Fusarium meridionale is seedborne in corn. While the pathogen has been isolated from corn ears and kernels exhibiting rot, suggesting a potential association with seeds, the specific role of seeds in its transmission has not been established.
