Alternaria blotch causes severe foliar defoliation to apple trees in Himachal Pradesh. Sixteen isolates of Alternaria spp. were collected from different locations and characterized for cultural variations. Alternaria alternata f. sp. mali varied in their cultural behavior ranging from velvety to cottony, mostly appressed, with regular to irregular margins. Colour of colonies ranged between light to dark olivaceous. The nutritional studies were undertaken to know the best medium required for the growth and sporulation of the test pathogen. The study revealed that out of six different solid media tested, potato dextrose agar (PDA), malt extract agar and Asthana and Hawker’s agar medium proved best for mycelial growth and sporulation of the test pathogen, respectively.
