Identification
This pathogen attacks all portions of the plant but is most commonly found on stems. White, relatively coarse mycelia grow in a fan-like pattern and may be seen on the soil surface or stems. The round sclerotia form almost anywhere on the plant or soil surface. Sclerotia are initially white and cottony and approximately the size of a mustard seed. As sclerotia mature, they turn tan, then eventually, they turn dark brown and hardenPrevention
