Bacillus subtilis (Bbv57) Strain Controls Post Flowering Stalk Rot of Maize caused by Fusarium verticillioides

Among the treatments implied under artificial epiphytotic conditions, Seed treatment (10 g/kg) with Bacillus subtilis (Bbv57) and Soil Application (2.5 kg/ha) recorded lower Fusarium Post Flowering Stalk Rot incidence (3.8 %) compared with Untreated control (8.9%). Among the treatments implied at infected fields of Vagarai and Keeranur, Seed treatment (10 g/kg) with Bacillus subtilis (Bbv57) and Soil Application (2.5 kg/ha) recorded lower Fusarium Post Flowering Stalk Rot incidence (2.0% and 1.04%) compared with Untreated control (7.5% and 3.56%) in both hot spot areas with yield of 5 to 6 t/ha. This study indicated that, Bacillus subtilis (Bbv57) was found to be a potential bio control agent for controlling stalk rot of maize.
