- Background
- Corn in Pamlico County was being scouted and it was observed that 90% of the field was affected by dieback and leaves were browning between the veins and mottled spots. It was also observed that some of the plants had strange looking brace roots. A samples was submitted to the PDIC for diagnosis. The site is high, dry and sunny.
- Conclusion
- The cause of the spots was diagnosed as Curvularia leaf spot. Curvularia leaf spot is caused by a fungus. Its lesions tend to occur on corn leaves following rain during reproductive maturity. In the U.S., it's considered mostly an aesthetic issue rather than a yield-limiting disease.
