Detection and pathogenicity of fungal pathogens causing black point disease of wheat

Abstract

The present investigation was carried out on the “Studies on Seed Borne Mycoflora of Wheat with Special Reference to Black Point Disease” with a view to assess seed borne pathogens associated with black point disease of wheat and their pathogenicity. Three seed borne pathogens associated with black point disease of wheat viz., Alternaria alternata, Drechslera sorokiniana and Curvularia lunata were detected on wheat seeds. The internally two fungi identified were Alternaria alternata and Drechslera sorokiniana. All the isolated pathogens were found pathogenic to wheat resulting into reduction in seed germination and seedling vigour index. The seed borne pathogen viz., Alternaria alternata, was found more dominant and damaging.
