Persistent rains during the past two weeks have resulted in ponding and saturated soils in many Ohio corn fields and led to questions concerning what impact these conditions will have on corn performance.

Leaf striping (interveinal chlorosis) in corn is appearing in many Ohio fields.  There are several nutrient deficiencies (including sulfur, zinc, magnesium, and manganese) that result in leaf striping and some of these look similar. The severity of the striping may vary considerably within a field and may be associated with differences in soil pH, organic matter, compaction, tillage, temperature and moisture. Bright yellow to white interveinal striping running the length of leaves may be the result of “genetic stripe”, but it’s usually limited to scattered plants within a field.
