Evaluation of Efficacy of different Fungicides againstFalse Smutdisease in rice

Abstract

An attempt was made to evaluate the efficacy of fungicides against the false smut disease of ricecaused by Ustilaginoideavirensat farmer’s field in different locations of Bhagalpur district (Bihar) during the two consecutive kharifseasons of 2013and 2014. The results revealed that all the tested fungicides showed significantly better performance over control (Farmers practice). Technology option (TO3)seed treatment with Carbendazim @ 2g/kg seed and twospraysof Propiconazole @ 1 ml/lhas shownthe minimum disease severity (20.3%) over the all technology option and farmers practice (control). Significantly maximum grain yields (36.5 q/ha) was also obtained from technology options (TO3), which was statistically superior over TO2seed treatment with Carbendazim @ 2g/kg seed and one foliar spray of Propiconazole @1ml/l and technology option (TO1) seed treatment with Carbendazim @ 2g/kg seed and one foliar spray of Carbendazim @2g/l, whereas minimum yield (18.3 q/ha) was obtained from control
