A distinct discoloration or rotting caused by a fungus that attacks ears of weakened plants. Since the damage is distinct, it is unnecessary to open the kernel for examination.

 

Illustration shows from left to right:

Kernel A: Minimum area of coverage and degree of discoloration necessary to be considered "distinctly discolored" corn.

Kernel B: Minimum area of coverage and degree of discoloration necessary to be considered "rotted" corn.
