Alternaria blight disease of mustard caused by a necrotrophic fungus Alternaria brassicae (Berk.) Sacc. Is one of the most important limiting factors, causing yield losses of up to 47% in mustard (Brassica juncea). The aim of this present investigation was to evaluate the fungicidal effect of non-conventional chemicals viz. calcium sulphate (CaSO4), potassium chloride (KCl), potassium sulphate (K2SO4), zinc sulphate (ZnSO4) and borax (Na2B4O7.10H2O) against alternaria blight disease of mustard. The significantly minimum size of spot was recorded in T1 CaS at 0.5% (1.73) followed by T3 CaS at 1.5% (1.75) and T2 CaS at 1.0% (1.78) respectively in comparison to check. The minimum number of average leaf spots/25 mm2 leaf area was observed in T3 CaS at 1.5% (1.78) followed by T1 CaS at 0.5% (2.26). T1 CaS @ at 0.5% showed significantly lowest disease index (13.00%) followed by T15 NaB at 0.75% (17.77%) and T8 KS at 1.0% (18.00%) respectively over check. The average minimum apparent infection rate was recorded in T1 CaS at 0.5% ( 0.504) followed by T9 KS at 1.5% (0.553) and T3 CaS at 1.5% (0.573) respectively. The AUDPC was significantly minimum in all the treatments of CaSO4 i.e. in T1 CaS at 0.5% (32.25), T2 CaS at 1.0% (33.8) and T3 CaS at 1.5% (35.55) in comparison to check (77.95). The foliar spray of CaSO4 at 0.5% concentration induced resistance significantly against alternaria blight and reduce pesticide residue in food and environment.
