Abstract: Occurrence of leaf blight disease has become a major constraint for cultivation of mung bean. Considering the fact, below investigation was carried out for this pathological problem. The efficacies of various botanicals were evaluated against Macrophomina phaseolina causing leaf blight of mungbean. The phyto-extracts of six plant species were evaluated in vitro by poisoned food technique against M. phaseolina. The finger extract of Turmeric having fungal colony diameter of 24.03 mm allowed minimum growth of the pathogen followed by clove extracts of Garlic (68.44 mm), finger extract of Ginger (78.13mm) and leaf extract of Black Tulsi (82.00 mm). Six fungicides were tested in vitro against M. phaseolina i.e. Thiram Carbendazim, Captan, Benomyl, Mancozeb and Tricyclazole by poison food technique. Mancozeb, Benomyl and Tricyclazole completely inhibited the mycelial growth followed by Thiram (1.8 mm), Carbendazim (61.24 mm) and Captan (72.38 mm).
