Fusarium Ear Rot of Corn
scouted Sept. 15, 2025
- Scientific Name
- Fusarium sp.
- Background
- Corn in Camden County was being harvested, and it was observed that corn cobs of blue/green and gray/white coloration were coming out of the back of the combine. The husk is blue on many of the ears as well. Some of the corn grain has a green/blue hue to it, especially at the tip of the ear. Widespread across the planting of this hybrid, not reported in other hybrids grown by the same grower. A sample was submitted to the PDIC for diagnosis.
- Conclusion
- The cause for this was identified as Fusarium ear rot. This was identified by the staburst symptom that is caused by the fungus growing under the kernel pericarp. Fusarium ear rot is associated with fumonisins, which can cause fumonisin poisoning. Swine and equine are the most sensitive to fumonisins.
