Title : Soilborne Pathogen
Type : Resumes
1. The fungus Sclerotium Rolfsii
The fungus S. rolfsii is Athelia Rolfsii, belonging to the
Agonomycetes fungus group (Fichtner 2010). Fungi S. rolfsii is a fungal
pathogen that can cause several deadly diseases in plants such as stem rot,
wilting and damping off of sprouts. This fungus is a soil-borne fungus that
can survive for a long time in the form of sclerotia in the soil, occasional
fertilizers and diseased plant residues. This fungus can spread through
irrigation water and seeds on land that is continuously planted with host
plants of S. rolfsii, so that resulting in decreased production of crops to be
harvested (Timper et al. 2001)
The fungus S. rolfsii is white like a feather. Primary hyphae cells at
the edge of the colony are 4-9 mm wide and up to 350 mm long. In the
sclerotia layer there are bubbles which are food reserves. The inside of the
old sclerotia contains sugars, amino acids, fatty acids and fats while the
walls contain sugars, chitin, laminarin, fatty acids and 1-3 glucosides.
Control:
1. Control can be done with better soil cultivation, making good drainage
and wide spacing
2. Using varieties that are resistant or resistant to this fungus
