Symptoms: the stem base down to the roots turns dark brown, rots, and the young leaves lose vigor and wither.
Prevention and treatment methods: (1) Ventilate promptly and keep the growing environment dry. (2) Pay attention to disinfecting the growing medium and flower pots.

(4) In the early stage of the disease, spray the aboveground parts every 10 days with a 1000-fold dilution of 50% thiophanate wettable powder, or an 800-fold dilution of 70% thiophanate-methyl wettable powder; drench the underground parts 2 to 3 times with a 400- to 600-fold dilution of 70% mancozeb wettable powder. 5.
