Bleaching of corn leaves may happen for several reasons like,
1. Sun scalding: High temperature resulted in bleaching of the top leaves.
2. Frost injury
3. Fertilizer burn
4. Herbicide burn
5. Mechanical injury
6. Insect damage
7. Some time may happen due to hybrid difference
How many plants are damaged? Which is the variety? And how is the weather there? Did you apply any fertilizer or herbicide in the field?
