The efficacy of seven fungicides and seven bio pesticides were evaluated invitro against isolates of A. alternata, among the different fungicides tested, the maximum inhibition was recorded by hexaconazole () with of per cent inhibition, followed by propiconazole () and tebuconazole () and the least inhibition was recorded by carbenazime with per cent. Among different isolates the 100 per cent inhibition was recorded by many isolates against triazole fungicides and the least inhibition was recorded by isolate Aa353 on Chlorothalonil (). Among different bio pesticides tested the maximum inhibition per cent was noticed in Garlic bulb extract with mean per cent inhibition of per cent followed by Neem leaf extract (), whey ( %) and cow urine ( %). The lowest inhibition was recorded by desi cow milk with mean inhibition of per cent. Among different isolates Aa1728 () showed maximum inhibition by neem leaf extract and least was recorded by Aa 1729 () on desi cow milk. | In vitro evaluation of fungicide and bio-pesticides against isolates of alternaria alternata (Fr.) black spot
