Lycopene, a low-calorie antioxidant element, is the primary carotenoid found in tomatoes. It is an abundant source of vitamins, minerals, fibers, and various phytochemicals that provide vital human health and immunity benefits against various disorders. Tomato fruits have a significant role in human nourishment.
This is because tomato fruits can be consumed as raw, cooked, processed, and have good palatability.
The increasing trend in tomato production and consumption is continuing. Based on the worldwide production, tomato currently ranks 7th after maize, rice, wheat, potatoes, soybeans, and cassava. Presently, this plant is extensively grown worldwide and has become a significant vegetable crop. Europeans distributed the tomato from the Americas to other parts of the world during the 16th century. It was native to South America, and domestication has occurred in Central America. Tomato ( Solanum lycopersicum L.) is affiliated to the Solanaceae family that includes a large number of economically essential vegetables. subtilis PPB9 for growth promotion, nutrient acquisition, and biocontrol of southern blight disease in tomatoes. The results show the potential capabilities of S. Bacteria colonized the entire roots, and their populations increased significantly in the protected plants. Bacteria-inoculated plants had a higher yield than those in the non-treated control. The sclerotial counts decreased significantly in these soils. The application of antagonists on container-grown seedlings in a greenhouse environment and field-grown tomato plants reduced symptoms of damping-off and Southern blight.
Significant increases in plant growth, chlorophyll contents, and N, P, and K concentrations were attained in bacterized plants compared to non-treated controls. subtilis PPB9 improved seed germination and tomato seedling vigour. They showed the potential to solubilize phosphate and fix nitrogen. The strains produced hydrogen cyanide, chitinases, siderophores, biofilm, and indole acetic acid. rolfsii was significantly inhibited by both rhizobacteria and supported their growth as a carbon source. rolfsii in dual culture (PPB3 88% and PPB9 71% inhibition), and culture filtrate assays (PPB3 53–100% and PPB9 54–100% inhibition at various concentrations). Of the six strains screened, Stenotrophomonas maltophilia PPB3 and Bacillus subtilis PPB9 showed the superior performance displaying the highest antagonism against S. The selected promising strains were tested further for plant-growth-promoting and biocontrol potentials under in vitro, greenhouse, and field conditions. rolfsii in dual culture and culture filtrate assays. The present study screened six rhizobacterial strains for antagonism against S. Although rhizobacteria are prolific candidates, comprehensive reports regarding their use in tomato disease management are limited. The use of rhizobacteria for the biological control of Southern blight disease is a potent alternative to chemical fungicides. Southern blight of tomato caused by Sclerotium rolfsii can cause severe plant mortality and yield losses.
