  • Krishi Vigyan Kendra, Khowai, Tripura, 799 207, India


Bacterial wilt of tomato caused by Ralstonia solanacearum is the dreaded diseases causing severe yield loss (25-75%) in farmers field. A field experiment at demonstration farm of KVK West Tripura was conducted for the evaluation different chemicals, botanicals and bioformulation against the disease. The study revealed that all the treatments were significantly effective over the control. However, soil drench with antibiotic @ 100 ppm was found best with lowest (23.6%) disease incidence and highest yield (228.2 q/ha). This was followed by copper oxychloride in terms of disease incidence (28.4%) and Biofor Pf in terms of yield (220.6 q/ha). Highest disease incidence (78.67%) with lowest yield(86.5 q/ha) was recorded in control plot.
