Cotton (Gossypium hirsutum L.) is the one of the most important commercial crops of the world, which belongs to the family Malvaceae. India is the largest cotton growing country in the world with an area of around 12.35 M ha accompanied by United States and China with production of 36.1 M bales and productivity of 524 kg lint/ha. Cotton crop is known to suffer from number of fungal, bacterial and viral diseases. In India foliar diseases have been estimated to cause yield losses up to 38 per cent. Cotton is under persistent threat of foliar diseases like grey mildew, Alternaria leaf spot, Myrothecium leaf spot, bacterial leaf blight, rust etc. Cultural variability among the twelve isolates were studied by growing isolates on different media i.e., Cotton leaf extract agar, Potato dextrose agar, Oat meal agar. Among the media tested, cotton leaf extract agar supported good growth of the fungus with excellent radial growth and high sporulation followed by potato dextrose agar and while least sporulation was observed on Oat meal agar.
