ABSTRACT
The study was conducted at the Molecular Plant Pathology Laboratory, Department of Pathology, Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during 15 November to 15 February, 2015 to investigate the effect of salicylic acid (SA) and Bacillus suspension based formulation on bacterial wilt of tomato. Chemicals are either hazardous for environment or less effective against Ralstonia solanacearum causal agent of bacterial wilt of tomato. The effect of SA and Bacillus subtilis on the severity of bacterial wilt and growth of tomato seedling were evaluated. Result showed that combination of SA and Bacillus recorded best performance compared to control and their sole performance. Plant growth such as plant height, branch per plant, fruit per plant and yield per plant were also enhanced by the combined application of SA and Bacillus subtilis. Collectively, SA and Bacillus subtilis proffer a remedy of an environmentally sustainable approach to increase crop production and enhancement of public health.
Keywords: Bacteria, Wilt, Salicylic acid, Bacillus and TTC.
