ASPEPA
Aspergillus parasiticus is a fungal pathogen commonly found in maize and peanuts. It is widespread in soils, crop residues, and air worldwide. It typically thrives in warmer climates and high moisture areas, particularly in the field and storage. A. parasiticus can be spread by contaminated soil, decaying plant material, airborne spores, insects, and direct contact. It is known to produce aflatoxins associated with cancer in humans and animals.

In maize, Aspergillus parasiticus targets kernels, particularly in plants weakened by stress such as heat or drought, which causes ear rot in the field and storage rot. A.parasiticus is most commonly found in areas with high temperatures and high humidity, in the United States this is sporadic in the Midwest but a chronic problem in the Southeast. It can cause major seed deterioration, affecting the seeds viability and germination.

Agar plating, Blotter, PCR
Though blotter incubation assays are commonly used for fungal contamination of seed, no references were found indicating this test has been validated or standardized.

Early identification and treatment of A. parasiticus through field inspections, adequate watering during production, and using resistant varieties can greatly reduce or potentially prevent economic losses from contamination. Best management practices for harvest time and proper storage can also be impactful.
