ROLE OF FUNGAL SCLEROTIA IN THE EPIDEMIOLOGY OF ASPERGILLUS FLAVUS IN MAIZE
Sclerotia of Aspergillus flavus produced in preharvest maize are dispersed into soil with debris during combining. Overwintered sclerotia germinate sporogenically and produce yellow-green conidial heads. Germination occurred prior to the silking date for maize in southern Georgia. The presence of a...

| Summary: | Sclerotia of Aspergillus flavus produced in preharvest maize are dispersed into soil with debris during combining. Overwintered sclerotia germinate sporogenically and produce yellow-green conidial heads. Germination occurred prior to the silking date for maize in southern Georgia. The presence of a maize canopy indirectly promotes germination via shading, so providing a microclimate at the soil surface with sufficient moisture. Soil micro-arthropods consume the conidia from germinated sclerotia, , dispersing inoculum throughout the soil. The aflavinines are major components of A. flavus sclerotia with substantial antifeedant activity against Carpophilus hemipterus (Nitidulidae), a detritivorous beetle that commonly encounters fungal sclerotia in crop residues. |
