Aspergillus ear rots

Aspergillus spp.

Symptoms: Patches of green to yellow spores on or between kernel. Most common at tip of ear and scattered on a few kernels on ear. The fungus can become dark green to brown as it ages. Aspergillus flavus and other Aspergillus can also cause storage rot. In favorable conditions, Aspergillus can invade kernels with moisture levels as low as 14%. Kernels are more likely to be invaded by fungi if they have come from rotted ears or if they have been damaged.
