Morphological characteristics, growth pattern, colony morphology and microscopic examination of three potent toxic isolates of Alternaria species collected from different regions in India. All the Alternaria isolated were grown on PDA culture media and incubated at 28 °C for 12 h light/dark photoperiod. The pictures of the colonies were taken at 6^th day after incubation of pathogen. Note: The names of the Alternaria isolates were given as abbreviation of the different plants from which they were isolated (details described in Table 1).
