 Cause:  Environmental. 

 Occurrence:  Color banding of leaves may occur soon after emergence or during early growth.  The problem is more prevalent during periods of warm days with cool nights. 

 Key Symptoms: 

·         Bright yellow bands alternate with normal green tissue on leaves.

·         Banding may be related to cultivar

·          

Problem:   Color banding may occur when cold or frosted tissue is exposed to bright sunlight or by surface soil heat.  It is most common on young seedlings but may also occur during early growth.

Management Approaches

Plants normally grow out of the damage.
