Abstract
Root rot of pawpaw (Carica papaya L.) reported in Nigeria is caused byPythium aphanidermatum which was consistently isolated from diseased plant parts and highly pothogenic. Out of 16 different media tested, it grew best on corn-meal-agar (CMA) and CMA supplemented with cellulose and sucrose. The highest number of oospores/ml was on CMA with average diameter of 19.9±0.1 µm. The symptom is characterized by dark brown rot of roots, absence of secondary roots and disintegration of internal tissue of the main root. These cause the progressive decline of the aerial parts of the tree untill it dies.
