A study on management of Alternaria leaf blight of tomato was carried out in year 2015-2016. Under in vitro evaluation of the botanicals drake (Melia azedarach) has highest efficacy of 63.52 per cent inhibition of the average mycelial growth of the Alternaria solani. However the least effective botanical was Urtica dioica with 36.30 per cent of mycelial inhibition. Among the fungicides most effective was score which inhibit the mycelial growth upto 78.61 per cent followed by 76.67 per cent of carbendazim. Minimum inhibition of the mycelial growth was recorded in kavach (50.74%). Under in vivo (pots) evaluation the highest efficacy of score was recorded when sprayed at 0.05 per cent concentration with disease severity of 16.33 per cent and disease control of 74.89 per cent followed by carbendazim fungicide (18.00%, 72.30%) when compared with control while the least efficacy was observed with the fungicides kavach (33.67%, 48.22%) and insignia (26.00%, 60.00%).
