Abstract: Stem rot of mustard is the most important and serious disease in all over India. It is mainly caused by Sclerotinia sclerotium. The pathogen was tested with six fungicides and two bio-pesticides. The fungicides manly Propineb, Mencozeb, Sulphur, Thiomethile, Copper oxychloride and Carbendazim and bio-pesticides were Garlic oil and Ginger Oil. All the tested fungicides and bio-pesticides were reducing the growth of pathogen In- Vitro condition except control. Among the tested fungicides Propineb and Mencozeb were found most effective fungicides inhibit the growth of the pathogen is 100%. Sulphur and Thiomethile which were sowed 71.47% and 70.45% inhibition over control respectively. Whereas Copper oxychloride and Carbendazim was least effective showed 41.17% and 47.05% inhibition over control. In-Vitro condition Propineb and Mencozeb was most effective fungicides which were showed minimum disease incidence and maximum yield in both the year of 2017-18 and 2018-19. The minimum disease incidence 9.46 and corresponding yield 23.09 was recorded in 2017-18. Next best order of superiority fungicide were Sulphur, Thiomethile , Copper oxychloride and Carbendazim, which were showed average disease incidence 9.92 to 15.03 and yield from 20.52 to 13.50 q/ ha grain yield. Among the bio-pesticides Garlic oil and Ginger Oil were least effective. Chemical which was showed maximum disease incidence 56.84 and minimum corresponding yield 11.50 q/ha in the year of 2018-2019.
