Leaf blight disease caused by Alterneria solani is one of the prime diseases of tomato and is pervasive in almost all the tomato growing countries. The fungicidal phenomenon of the botanical extracts against leaf blight disease of tomato was evaluated under laboratory and greenhouse conditions. Extracts of Eucalyptus obliqua, Calotropis procera, deoiled cakes viz., Neem (Azadirachta indica), Mustard (Sinapis arvensis), groundnut (Arachis hypogaea), Karanj (Millettia pinnata), Mahua (Madhuca longifolia), Castor (Ricinus communis), Salmeal (Shorea robusta) and cow urine were evaluated singly or in combined form to examine the efficacy for inhibition of the fungal pathogen. The treatments were done on various isolates of A. solani in the different concentrations of 5%, 10%, 15%. Extracts in the combined form viz. Eucalyptus obliqua (10%) + Neem cake (Azadirachta indica) (10%) + cow urine (0.5%) showed the maximum inhibition of 85.3% in the laboratory experiments and 78 % in the greenhouse conditions as compared with untreated control. The minimum inhibition of 61.6% in percent disease index was exhibited by Calotropis procera + Karanj cake (Millettia pinnata) + cow urine (0.5%) in greenhouse conditions. Environmental suitable techniques could prove to be promising approach against the harmful and expensive chemical fungicides. The use of such crop yielding organic extracts can be suggested to farmers for inhibition of A. solani.
