Narcissus fire is a fungal disease which affects the petals and leaves, but does not affect the bulb. It is favored by warm, humid weather and can spread very quickly under these conditions. Flowers are attacked first, with watersoaked spots appearing at the margins and enlarging rapidly. The spots later turn brown and wither. Leaf infections follow flower infections. Initial leaf symptoms include development of yellow, elongate spots near leaf tips. The centers of the spots turn grayish or brown as the spots enlarge. The leaf above the infection point dies and droops. The fungus survives in infected plant tissues and on plant debris in the soil.
