Stem- and rootrot


There are different types of fungi that stalk the roots and the base of the plant. Once affected the plants wither and die quickly. When finding these fungal species, remove the affected areas as soon as possible and treat them with a fungicide like Topsin, Previcur, benomyl (does not work against Phytophthora, Fongarid, Maneb or Zineb).

Stem rot or white rot can be caused by Scerotium rolfsii. On the stem light brown translucent spots appear and the stem nods. Also the roots can rot. The fungus prefers high temperatures and high humidity.
