Abstract: Among the various causes of biotic diseases namely downy mildew, Alternaria blight, white rust, powdery mildew and wilt are widely prevalent diseases of Indian mustard in Eastern U.P. Alternaria proved most devastating disease in Indian mustard and causes heavy loss in seed yield. To manage the Alternaria blight, a field trial was conducted in 2012-13 and 2013-14. Two test varieties namely Varuna and NDR8501 were sown on 20 October and 10 November and four fungicides namely Mancozeb, Folicur, Quintal and Nativo were used to managing the disease. The minimum interaction effect between date of sowing (1st date of sowing), variety (NDR8501) and fungicide (Folicur) was 2.59 and 4.35 for leaf blight, 0.00 and 0.00 for pod blight, 4.22 and 4.08 for test weight and 1886.18 and 1685.59 for seed yield, respectively in 2012-13 and 2013-2014.
