Tomato (Solanum lycopersicum L.) is one of the most important vegetable crop belongs to family Solanaceae. The production quality of tomato affected by array of biotic and abiotic stresses. Of these, biotic factors especially viruses are major constraint in tomato production. Among viruses infecting tomato, Tomato leaf curl virus (ToLCV), Tomato spotted wilt virus (TSWV), Cucumber mosaic virus (CMV), Tomato mosaic virus (ToMV), and Tobacco mosaic virus (TMV) presently known to contribute consistently to yield losses of tomato crop.

Tomato (Solanum lycopersicum L.) is the third most important crop in India that suffers from various biotic and abiotic stresses. Among the biotic stresses early blight caused by Alternaria solani [(Ell. and Mart.) Jones and Grout] is one of the most destructive diseases of tomato which leads losses up to 78 per cent. In the present study efficacy of cow by product and fungicides were evaluated against the pathogen in vitro and in vivo conditions.
