At higher disease levels, even greater losses can result. When a corn plant's ability to store and produce carbohydrates (glucose) in the grain is diminished, yield losses take place.

  8. Aspergillus flavus - Wikipedia

    en.wikipedia.org/wiki/Aspergillus_flavus

    The spores enter the corn through the silks and thus infect the kernel. Conidiophores and conidia are produced in the spring from sclerotial surfaces. There is a secondary inoculum for A. flavus, which is conidia on leaf parts and leaves. A. flavus grows on leaves after damage by leaf-feeding insects. Insects are said to be a source of inoculum ...
