Maize kernels were assayed for endogenous fungi at weekly intervals from 1 wk before the midsilk stage to 910 wk after midsilk. Fusarium moniliforme was first isolated 2 wk after midsilk and infection increased each week to 3566% at final assay. Cephalosporium acremonium was first detected 34 wk after midsilk and infection increased weekly to 3045% at final assay. Kernel infection by F. moniliforme in the tip half of corn ears before maturity and by C. acremonium in the butt half at maturity was most common.
