Alternaria leaf spot caused by Alternaria alternata is the most common disease in stevia, An experimental trial was taken up to evaluate the efficacy of selected eco-friendly treatments on the growth parameters in stevia over Alternaria alternata at Central Research Farm, Division of Plant Pathology, Naini Agricultural Institute, U.P. Maximum plant height (50.40 cm), Maximum number of branches (23) and minimum disease intensity (22.79%) are recorded in the treatment combination of T8 - Microalgae + neem cake + vermicompost followed by T6 – Microalgae + vermicompost.
