Field experiments were conducted to identify effective and economic resistance inducing chemicals for the management of Alternaria blight caused byAlternaria brassicae (Berk) Sacc. and Alternaria brassicicola (Schw.) Wiltshire under field condition by using Benzoic acid, Napthelic acetic acid, Salicylic acid, Phosphoric acid, Isonicotinic acid andIsonicotinic acid at 0.05 and 0.1% concentration. The entire test chemicals, reduced the disease severity on leaves and pods along with enhance yield as compared to check. Minimum disease severity of 25.33% and 27.06% on leaves and pods were recorded with Isonicotinic acid @ 0.1% followed by Benzoic acid @0.1% 28.66% and 30.0%, respectively. Maximum seed yield (1983.30 kg/ha) was also recorded withIsonicotinic acid @ 0.1% followed by same chemical @ 0.05% (1858.32 kg/ ha). Maximum net return with benefit cost ratio of 11.70 was recorded with application of Benzoic acid @ 0.05% followed by same chemical @ 0.10% (7.32).
