Aqueous extracts of five plants with anti-microbial properties were evaluated for suppression of growth of Alternaria solani in laboratory conditions. At low concentration of 2%, four extracts including (Azadirachta indica) failed to suppress the growth. One extract (Putranjiva roxburghii) showed significant suppression of pathogen growth at low concentration, according to Analysis of variance, Tukey’s post-test. Some extracts (Melia azedarach and Tabernaemontana divaricata) on the contrary promoted the growth significantly more than the negative control. Discovery of a plant with better anti-fungal property than Azadirachta indica is a significant out-come of the investigation. Putranjiva roxburghii extract shows potential for management of an early blight of tomato in organic farming and for the isolation of bioactive molecule.
