Study was undertaken to know the effective management strategy through novel bio control agents and botanicals against Ralstonia solanacearum a dreaded pathogen causing bacterial wilt of tomato. The study revealed that Bacillus subtilis was found to be most effective in inhibiting the growth of the pathogen followed by Pseudomonas fluorescens, by producing an inhibition zone of 22.50 mm and 18.00 mm in diameter, respectively under in vitro conditions. However, among plant extract tested Isabgol seed extract was found to be highly inhibitory to the growth of the pathogen in which inhibition of 22.00, 19.50 and 18.00 mm was observed at 1:0, 1:1 and 1:5 dilutions. Similarly under field condition, Bacteriophages and Bacillus subtilis were found to be very effective in reducing the disease incidence by 72.50 per cent and 64.58 per cent with reduced soil population of the pathogen both in soil and rhizosphere.Keywords

The experiment was conducted on powdery mildew of Chilli (Capsicum annuum L.) caused by Leveillulla taurica to know the effective management strategy. The pooled data revealed that there was significant effect of the treatments in reducing the disease. However, plants sprayed with Difenconazole (0.5g/L) as a second spray 15 days after the Chlorothalonil (2/L) was found to be effective in the management of powdery mildew, where in the PDI of 11.85 as against to control plot and also supported the higher yield of 13.4 t/ha in contrast to 9 t/ha in untreated control plots.Keywords
