Cross-Banding on Corn Leaves: One Week Later

Cross-Banding on Corn Leaves: One Week Later

May 17, 2017
Roger Elmore - Emeritus Extension Cropping Systems Agronomist

A May 12 CropWatch article discussed the cross-banding occurring on corn leaves in south central Nebraska fields. This effect was due to pre-emergent cold temperatures. The photos shown here were taken in the same areas at the South Central Agricultural Lab (SCAL) near Clay Center May 16. Early-season leaf damage like that shown in the photos in this article should not dramatically affect either growth or yield.
