* continue to rob yield potential from the crop.
* form at any time.
* fungal disease that can afflict the root system and result in death.
* fungus disease that causes the entire plant to wilt and die.
* is also high in tatipaka diseased palms.
* is caused by a complex of soilborne fungi
  - poor drainage or by excessive watering and fertilizing
  - favored by high soil moisture and warm soil temperatures
  - often a problem in wet soils
  - probably the most common plant problem indoors and is associated with overwatering
