Identification of seed-borne pathogens on rice cv. IR 50404 in An Giang

This study aims at identifying pathogens contaminating seeds of rice cultivar IR 50404 in An Giang province to study disease control methods. A total of 36 seed samples was collected from ten main rice cultivation areas of the province. Eight fungal pathogens were identified based on their morphological characteristics using the blotter method. They include Alternaria padwickii, Aspergillus flavus, Bipolaris oryzae, Fusarium moniliforme, Mucor sp., Penicilium sp., Curvularia sp. and Sarocladium oryzae. These results serve as a basis to develop effective control methods for seed transmitted diseases in rice fields.
