Abnormal Corn Ears

Pinched Ears (Beer Bottle)

Reduced kernel row number part way up the ear due to inhibition of cell division in ear development by sulfony/urea herbicide

Diplodia Ear Rot

infection occurs with prolonged wet conditions in late vegetative stages through silking. kernels develop normally but are colonized and degraded by fungus

Tassel Ears

Combination tassel and ear in same structure at top of stalk

Tip Die Back

If aborted kernels are present at the ear tip

Blunt Ears (Beer Can)

Inhibition of ovule development, reduction in potential kernel number along length of row

Zipper Ears

Ears with missing kernel rows

Drought Damaged (nubbin ears, nosing back)

Small ears, small kernels, unpollinated

Kernel Red Streak

Red discoloration on kernels resultign from wheat curl mite feeding at late grain fill stage

Incomplete Kernel Set

Poor or scattered kernel set in the ear

Crazy Top

Caused by infection by a fungal pathogen. proliferation of small ear shoots, leaves, and lack of ear and tassel formation

Arrested Ears

Ear development arrested or stopped prematurely
