Onion black spots are caused by a fungus called Aspergillus Niger. The fungus thrives in warm and humid conditions, leading to the development of black spots on onions. To prevent black spots, onions should be stored in a cool, dry place with good air circulation. Additionally, proper crop rotation and avoiding planting onions in the same area year after year can help reduce the risk of fungal infections. If black spots are already present, affected onions should be removed and discarded to prevent the spread of the fungus.
