Management of Bacterial Wilt of Tomato through an Innovative Approach

Abstract

Bacterial wilt of tomato caused by Ralstonia solanacearum is dreaded disease causing severe yield loss (25-75%) in farmer's field. A field experiment at demonstration farm of KVK West Tripura was conducted for evaluation of 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.
