It is a coarse looking, perennial shallow rooted plant with a short stem, 30-60 cm high and can be grown even in dry lands under rainfed situation. During survey, Indian Aloe were found infected with Root rot caused by Fusarium solani causing severe damage at seedling stage both in the field of Jobner vicinity during Spring season 2011-12. The effect of different levels of temperature (15, 20, 25, 30 and 35°C), relative humidity (60, 70, 80, 90 and 100 percent) and pH (5.5, 6.0, 6.5, 7.0, 7.5, 8.0 and 8.5) on growth and sporulation of the pathogen were tested in vitro conditions. Maximum mycelial growth and sporulation were found at 250C temperature (84.15 mm), 100 per cent relative humidity (88.50 mm) and maximum dry mycelial weight at 6.5 pH (270g).
