Effect of bio-intensive strategy on disease management in mustard ( Brassica juncea )

Field trial comprising of two integrated disease management module (based on bio-intensive input and Chemical fungicide) was conducted for disease management in mustard at regional research station, Bawal (Rewari) of CCSHAU, Hisar, Haryana during 2017 to 2019. The results showed that soil application (2.5 kg /ha) and seed treatment (10 g /kg) with Trichoderma viride (NCIPM / T-9 strain) followed by two foliage spray of freshly made garlic clove extract @2% (w/v) was better than seed treatment with carbendazim 50WP (1 g a.i. /kg) followed by its two foliar spray @ 0.5 g a.i. / l of water in significantly reducing the diseases and increasing the seed yield. Minimum white rust (32.2%) and Alternaria leaf spot (28.3%) disease severity, Sclerotinia stem rot (4.6%) incidence and maximum seed yield of 2433 kg / ha was observed in bio-intensive IDM module in comparison to corresponding values of 38.1%, 34.2%, 7.6% and 2202 kg /ha in chemical fungicide.
