Fusarium ear rot is caused by a fungus that also infects stalks. It is closely related to gibberella ear rot. Besides directly reducing yield through damaged kernels, it can produce mycotoxins which are dangerous for humans and livestock.
Fusarium ear rot is grey or white in color. It occurs sporadically on kernels throughout the ear.
