Lanzhou lily is a valuable medicinal and food plant that loses 20-25% of its crop annually due to fungal rot during storage. Researchers identified the main culprit as a fungus called Fusarium oxysporum and found that natural essential oils from cinnamon, tea tree, and angelica plants can effectively inhibit this fungus’s growth. Cinnamon essential oil proved most effective and could serve as a natural alternative to chemical fungicides for protecting stored lily bulbs.
