Description The efficacy of 3 fungicides and 5 phyto-extracts against A. alternata were evaluated in vitro and in vivo in Adusa (Adhatoda vasica Nees). Mancozeb was found to be the most effective fungicide in checking the mycelial growth and conidial germination of A. alternata. It also gave maximum (64.60%) disease control when sprayed twice (@ 0.25%) on artificially inoculated Adusa plants. Among the 5 phyto-extracts tested, garlic (Allium sativum L.) clove-extract proved as the most effective treatment in checking growth and conidial germination of the pathogen and also in controlling the leaf blight. Two sprays of garlic extracts (@ 15%) gave 55.12% disease control on artificially inoculated A. vasica plants.
