Screening of fungicides against Alternaria alternata (Fr.) Keissler In vitro condition
Author(s): RB Rajput and SR Chaudhari
Abstract: Exploration on leaf spot disease (Alternaria alternata (Fr.) Keissler) of brinjal (Solanum melongena L.) under South Gujrat condition was carried out to find suitable management strategies. Ten fungicides from systemic and non-systemic groups were evaluated at three different concentrations by poisoned food technique in vitro for their efficacy against A. alternata. The results reveled that out of all ten fungicides screened at three concentrations, four fungicides were found significantly superior in inhibiting the mycelial growth and sporulation of A. alternata. However, cent per cent inhibition of A. alternata was recorded with Propiconazole (Tilt), Difenoconazole (Score) and Hexaconazole (Contaf) at all three concentrations (250, 500, 1000 ppm) tried and Mancozeb (Dithane M-45) at 2500 ppm. The next best in order of efficacy were Carbendazim (12%) + Mancozeb (63%) (Sixer 75 % WP) at 2500 ppm (93.05 %) and 2000 ppm (87.50 %). Copper oxychloride (Blitox) at 2500 ppm (86.11%), followed by, Propineb (Antracol) at 1000 ppm (77.77 %) and Tridemorph (Calixin) at 1000 (74.07%). The spore formation was totally inhibited by Propiconazole (Tilt), Difenoconazole (Score), Hexaconazole (Contaf), Copper oxychloride (Blitox) and Mancozeb (Dithane M-45) at all three concentrations. The next best in order of merit was Propineb (Antracol) at all three concentrations.
