An experiment was carried out to evaluate the effect of different essential oils, bio-agent and their combinations in in vivo conditions for management of early blight of tomato caused by Alternaria solani and also to increase the growth parameters and yield. A total of eight treatments taken as seedling treatment namely Neem oil (5%), Castor oil (5%), Clove oil (5%), Trichoderma viride (5%), Neem oil + T. viride (2.5%+ 2.5%), Castor oil + T. viride (2.5%+ 2.5%) and lastly Clove oil + T. viride (2.5%+ 2.5%) including control were replicated three times. During evaluation, all the seven treatments were found to be significantly superior over control in managing early blight and also in increasing the growth parameters and yield. Among all the treatments Neem oil + T. viride (2.5%+ 2.5%) followed by Neem oil (5%), Trichoderma viride (5%) were significantly superior over other treatments in reducing early blight infection and also in increasing growth parameters of the crop. Subsequently, cost benefit ratio was also most desirable with Neem oil + T. viride (2.5%+ 2.5%) followed by Clove oil + T. viride (2.5%+ 2.5%). Trichoderma viride is most effective with the combination of essential oils than the single treatment to control early blight disease intensity and also in increasing the growth parameters respectively and also found to be economic.
