The present work deals with the bio-efficacy of newer fungicides against sheath blight of potato, the most important disease of potato worldwide. All the fungicidal treatments recorded significantly less PDI in comparison to control. However, amisulbrom 20% SC (Kirari) applied @ 500 ml ha−1, recording minimum and significantly less PDI was found the most effective in producing disease free tubers and yielding significantly higher yields ie., 402.77 q ha−1 in 2013–14 and 380.06 q ha−1 in 2014–15 than other treatments.
