Penicillium Ear Rot

Penicillium spp.

Penicillium ear rot is caused by a fungus. Besides directly reducing yield through damaged kernels, it can produce mycotoxins which are dangerous for humans and livestock. It is favored by wet conditions at or shortly after silking and also by insect damage.
Penicillium ear rot causes a green or blue mold on the kernels or at the ear tip.
