What Causes Dry Rot In Potatoes?
Dry rot in potatoes is caused by a fungus called Fusarium spp. The fungus can enter through small cracks and wounds on the potato skin and then spread into the flesh, causing a dry, brown, and powdery rot. The fungus thrives in warm and moist conditions and can spread rapidly in storage or during transportation, which is why it’s important to properly handle and store potatoes to prevent dry rot. Crop rotation, proper soil drainage, and removing diseased or damaged potatoes can also help prevent the spread of the fungus.
