Tomato is one of the most important crops for vegetable growers due to its increasing demand for consumption worldwide. To meet this requirement of demand and supply, its production needs to be enhanced. But early blight disease in tomato caused by Alternaria solani (Ellis and Martin) is a major concern, reducing yield to manifolds. In the current study, different plant extracts like Garlic (Allium sativum), Neem (Azadirachta indica), Datura (Datura stramonium), Tulsi (Ocimum sanctum), Ginger (Zingiber officinale) and Onion (Allium cepa) were tested in in-vitro condition, using food poison method and fungicides like Hexaconazole 5% SC at two different dose rates and Trifloxystrobin 25% + Tebuconazole 50% WG were tested in in-vivo condition, to understand its efficacy against Alternaria solani in Tomato. Among the tested botanicals, maximum percent inhibition of pathogen was observed in Datura (45.45%) followed by Ginger (38.12%) and Neem (33.80%). While amongst fungicide formulations, both the doses of hexaconazole 5% SC i.e. 640 and 800 ml ha^-1 recorded better efficacy in controlling A. solani in tomato crop.
