Indian Mustard that is emerged as the core oilseed crop is cultivated in the northern regions of India during Rabi season. Alternaria blight is one of the most destructive pathogens for Indian Mustard resulting in huge losses in quality and quantity of the produce. A research study was taken up to control the alternaria blight in Indian Mustard with selected eco-friendly treatments by monitoring disease intensity and yield attributes. It is noted that T2 – Trichoderma viride has shown significant results on disease intensity and yield attributes, where disease intensity has significantly minimised in T2 may be due to the mycoparasitic nature and ability to generate volatile and non-volatile compounds against pathogen with great anti-microbial activity. The results showed that maximum plant height (56.10 cm), test weight (4.11 g) and seed yield (1.21 t/ha) of Indian Mustard with minimum disease intensity (40.21 %) were recorded in the treatment T2 and followed by T6 – neem leaf extract @15% that has shown significant results on Alternaria blight.
