Evaluation of Different Fungicides against False Smut Disease of Rice (Oryza satival L.) in North Bihar

Evaluation of Different Fungicides against False Smut Disease of Rice

Abstract

An attempt was made to evaluate the efficacy of fungicides against false smut disease of rice caused by Ustilaginoidea virens at the farmer’s field in different locations of Bhagalpur district (Bihar) during kharif 2013 and 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 two spray of propiconazole @ 1 ml/l has showed minimum disease severity (20.3%) over the all technology option and farmers practice (control). Significantly maximum grain yield (36.5 q/ha) was also obtained from technology options (TO₃), which was statistically superior over TO₂ seed 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 the minimum grain yield (18.3 q/ha) was obtained from control (Farmer's Practice).
