Black scurf of potato caused by Rhizoctonia solani is one of the most important disease in the category of soil and tuber borne disease especially in fungal group. Infested seed tubers are the main source of infection. Boric acid and pencycuron are the two chemicals which are frequently used by the Indian farmers to control black scurf of potato. New molecule: Thifluzamide 24% SC was evaluated for bio-efficacy and phytotoxicity effect against black scurf disease of potato during two consecutive years (2014-2016). Results revealed that Thifluzamide 24% SC @ 3.0 ml/10 kg seed was highly effective and resulted in reduction in disease incidence (95.69% during 2014-15 and 96.50% during 2015-16) and disease severity (97.39% during 2014-15 and 97.43% during 2015-16) with higher yield (42.93 t/ha) followed by Carboxin 37.5 + Thiram 37.5 WS @ 25 g/10kg tubers. The plant emergence percentage ranged from 90.22 to 97.39% at tested different doses of Thifluzamide 24% SC. No adverse effect on emergence (%) and on phytotoxicity parameters was observed when Thifluzamide 24% SC was tested at 2.5 ml/10 kg tubers. Thifluzamide 24% SC @ 2.0, 2.5 and 3.0 ml/10 kg seed tubers was effective against black scurf of potato by slurry treatment.
