Penicillium spp.
Nature of damage
- Damage is caused by rotting of kernels leading to direct yield loss.
- Rotting of stored grain can lead to post-harvest losses.
Signs
- A conspicuous, light blue-green powder grows between kernels and on the cob surface.
- Kernels with fungal growth normally become bleached and streaked.
Factors favoring development
- Ears are most vulnerable to infection following mechanical damage or injury caused by insect damage.
- Grain stored at high moisture levels.
Geographic damage
- Worldwide distribution
