Abstract:
Brassica juncea (L.) Czern. & Coss. is commonly known as Indian mustard and globally used as oilseed, vegetable and cosndiments. Alternaria brassicae is the most destructive pathogen of oilseeds. In this present investigation five plant extracts and five fungicides were used under in vitro through the use of poison food technique (PFT) and Standard Blotter Test (SBT) and under in vivo conditions through the use of seed application, foliar application and seed + foliar application. Present data revealed that, among fungicides used as seed treatment in vitro, mancozeb + carbrendazim, proved to be the most effective against Alternaria brassicae followed by captan + hexaconazole in improving seed germination and vigour index by reducing pre and post-emergence mortality. Similarly, among botanicals tested in vitro, garlic extract proved to be effective in inhibition of mycelial growth and improving seed germination and vigour index by reducing pre and post-emergence mortality followed by NSKE. Seed treatment and then foliar application (50 DAS) of mancozeb + carbendazim (0.2%) and garlic extract (10%) were proved most effective in reducing disease intensity. Mancozeb + carbedazim and garlic were found most effective in inhibition of mycelial growth in in vitro and in reducing disease intensity as well in in vivo.
