In vitro efficacy test of fungicides against Ustilaginoidea virens causing false smut of rice

Rice false smut caused by Ustilaginoidea virens (Cke.) Tak. is an emerging threat now a days. It causes both qualitative and quantitative yield losses. The present study is carried out to evaluate the efficacy of five fungicides against Ustilaginoidea virens. The result revealed that the complete inhibition was observed under treatment Propineb, Propiconazole, Carbendazim 63% + Mancozeb 12% and Tebuconazole 50% + Trifloxystrobin 25% while in Kresoxim methyl, inhibition per cent is 57.69 and 69.98 at concentration 0.1% and 0.2% respectively in in vitro condition.
