Symptoms occur mainly at the base of bulbs or stems. After germs infiltrate the bulbs, water-stained dark brown lesions develop. The lower leaves of the plants begin to turn yellow. The plants wither and wilting, splitting the surface layer of the soil, and the bulbs are tangled with radial white hyphae. The Ministry of disease can be seen in dark brown sclerotia.

Transmission routes and disease conditions Bacteroides can invade the bulbs, tuberous roots, roots, stems and leaves of the lily that are in contact with the ground through the bulbs of the bulbs or directly from pathogens in the soil. When the ball is carried by the ball, it invades the outer scales of the bulb or the root buds. When the climate is suitable for the growth of the mycelium, it begins to grow quiescent mycelium and secrete hydrolytic enzymes to destroy the host tissue; When the sclerotia germinates or the mycelium on the plant residue contacts with the bulb outer layer scales or roots, the stem base and the root system, it will also cause damage, resulting in the obstruction of water absorption, the yellowing of the lower position leaves of the plant, further expansion of the disease, resulting in the whole plant withering death. When the temperature and humidity are suitable for the growth of mycelium, white quill-shaped mycelium filaments are generated on the surface of the stem or the root of the ratoon root to expand radially, and yellow brown to dark brown nucleus is generated above.
Beeswax is obtained from the honeycombs of bees after the Honey has been removed by draining or centrifuging. The combs are melted with hot water, steam or solar heat; the melted product is filtered and cast into cakes of yellow beeswax.
