Bacterial infections in popcorn include Stewart's wilt caused by Pantoea stewartii, bacterial leaf streak incited by Xanthomonas vasicola, and ear rot associated with Bacillus mesentericus.

In the reference 5 varieties crop Popcorn, where this is mentioned in the description.

Stewart's wilt, caused by Pantoea stewartii, manifests in young plants as a systemic infection leading to death, while in mature plants, it presents as longitudinal yellow streaks along leaf veins, often accompanied by bacterial exudate. The second major disease is bacterial leaf streak, caused by Xanthomonas vasicola.

Bacterial ear rot, caused by Bacillus mesentericus var. vulgatus, affects plants during the milk stage. The disease is characterized by the appearance of 2–3 mm diameter depressed spots on the tips of kernels, which eventually progress into yellow or brown ulcers; the development of this pathogen is often correlated with damage to the ears by the cereal bug.
