Disease management in Indian mustard (Brassica juncea) through integrated approaches

Field experiments were conducted during Rabi 2010-11 to 2012-13 to manage the prevailing fungal diseases of Indian mustard through integrated approach. Removal of three lower leaves followed by foliar spray of metalaxyl 8% + mancozeb 64% WP @ 2 g l–1 of water was found best in controlling the white rust (12.2%). Lowest Alternaria blight (6.1%) was recorded with seed treatment followed by one foliar spray of propiconazole 25 EC @ 1 ml kg–1 seed and 1 ml l–1 of water, respectively. Significant (P<0.05) reduction in stem rot incidence (0.6%), maximum average production (2988 kg ha–1), maximum net profit as well as the incremental cost-benefit ratio (ICBR) was observed with seed treatment of carbendazim 50 WP @ 2 g kg–1 seed followed by two foliar spray of carbendazim 12% + mancozeb 63% WP at 2 g l–1 of water.
