An experiment was conducted to evaluate the effect of three botanical extracts, two botanical fungicides and one essential oil in vitro and in vivo against Alternaria brassicae causing Alternaria blight of cabbage. Among the treatments basil essential oil was found most effective in the inhibition of mycelial growth of Alternaria brassicae followed by Oenanthol (castor based botanical fungicide), bloom buddy (neem based botanical fungicide), neem leaf extract, basil leaf extract and castor leaf extract at all the three different concentrations tested in laboratory condition as compared to untreated control.The botanical extracts and their commercial products were tested under field condition during rabi 2019-2020 for their efficacy against the disease. Among the treatments minimum percent disease intensity  was recorded in Bloom buddy (neem based botanical fungicide) @ 0.5% (23.35%)followed by Oenanthol (castor based botanical fungicide)@ 0.1% (25.15%), basil essential oil @ 2% (26.20%), neem leaf extract @ 25% (28.31%), basil leaf extract @ 5% (30.12%) and castor leaf extract @ 30% (31.50%) as compared to untreated control (34.43%).
