Medicinal plant Fritillaria mold

Symptoms Gray mold is one of the important diseases of Fritillaria. It mainly damages the leaves and stems. The leaves were infected with dark green dots. After the lesions expanded, the central yellow was brown and surrounded by dark green. The lesions had yellow halos around the lesions, so they were also called eye diseases. The leaf veins in the lesions are necrotic and the lesions spread to both ends, forming long strips of dead spots. Stem infected with dark green lesions, spread around the stem after a week caused by plant death.

The pathogen Botrytis elliptica (Berk.) Cowe is called Botrytis elliptica, a fungus belonging to the genus Deuteromycotina. The hyphae became white at first and turned dark brown later.

Conidia colorless to light brown, oval or spherical, unit cell, size 16-3215-24 (μm), the top with sharp protrusions. Sclerotia are formed in the later stages of mycelial growth. Sclerotia black, spherical or irregular shape, size 0.5-1.4mm.
