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.
NOTE: If kernels do not meet the interpretation, it may be necessary to open the kernels to determine if the kernels are otherwise damaged.
