FUSAMN
Fusarium meridionale causes head blight, ear rot, stalk rot, and root rot in corn. It produces mycotoxins, posing risks to food and feed safety. Where reported it is often the most aggressive and prevalent Fusarium species: in China, 40.5% of stalk rot infections and 29% of maize rot isolates, in Brazil, 97.8% of stalks and 67% of kernels, and in South Africa from root rot cases. Transmission occurs primarily via infected crop residues and airborne spores, dispersed by wind, rain splash, or mechanical means, facilitating infection of ears, kernels, stalks, and roots. Although the pathogen has been isolated from kernels, seedborne transmission has not been confirmed. Its ability to persist in multiple tissues and environments underlies its widespread occurrence and epidemiological success. Impact is significant due to high aggressiveness, competitive dominance over other Fusarium species, and mycotoxin production, resulting in potential yield losses, reduced grain quality, and food/feed safety concerns.

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