Abstract

Extract of garlic (Allium sativum), Neem (Azadirachta indica), BAU-Biofungicide (Trichoderma based preparation), Bavistin DF (Carbandazim) and Potent 250 EC (Propiconazole) were studied in in-vitro test to evaluate the efficacy of plant extracts, BAU-Biofungicide and fungicides on the inhibitory effects on some selected rice pathogen. BAU-Biofungicide (2 & 3%) showed significant effect in reducing mycelial growth of Bipolaris oryzae, Cercospora oryzae, Rhizoctonia solani and Ustilaginoidea virens. Potent (0.1%) showed excellent effect in controlling mycelial growth of Ustilaginoidea virens, Sarocladium oryzae, Rhizoctonia solani, Bipolaris oryzae and Cercospora oryzae. Bavistin (0.1%) was found to have better result in inhibiting the mycelial growth of Cercospora oryzae, Sarocladium oryzae and Rhizoctonia solani. Highest increase (16.67%) in seed germination was recorded over control when seeds were treated with BAU-Biofungicide (3%). BAU-Biofungicide (3%) also resulted in higher increase vigour index compared to control.
