ABSTRACT


Hermilia Sanz de Badilla1
 

The fungus Pythium debaryanum Hesse was isolated from potato tubers - Spartaan variety - showing "watery rot" (or "leak").
Pathogenicity tests were succesfull by inoculating - through wounds - sound potato tubers.
During storage the fungus was unable to propagate from diseased to healthy unwounded tubers.
This is the first information about this disease, and its causal agent, for our country.
