Abstract:
The present investigation titled “Morphological characterization of Alternaria spp. derived from different naturally infected crops” was carried out at the Department of Plant Pathology, College of Agriculture, IGKV Raipur (C.G) during 2020-21. Alternaria spp. were isolated from nine different naturally infected host crop. The symptomatology of diseases was observed in field. The different isolates were used for studying pathogen character. The study includes morphological characters i.e, length, width, beak of conidia, no of horizontal and vertical septa and cultural characteristic were observed. From this study, that Alternaria species was identifies with their unique necrotic lesions, which sometimes have a target like appearance due to growth interruptions and black sooty growth on the necrotic lesions. Microscopic preparations of Alternaria spp. conidia revealed unique conidial morphology respectively.
