Dematophora root rot—Dematophora or Rosellinia necatrix
Dematophora root rot, or white root rot, is not as common as other root rot fungal diseases are, but
when it occurs, it can quickly kill plants. Symptoms may be exhibited throughout the entire plant or in
just a portion of the canopy. Branches killed as a result of Dematophora often retain dry foliage. A white
mycelial mat may be visible on the lower trunk or in soil over infected roots.
Identification
Solutions
