Abstract
Management of soil borne disease of tomato with the aim of reducing the use of chemical pesticides and produce healthy products needs to provide appropriate policy. Grafting is one of the most effective control measures of soil borne pathogens result in healthy crop production and is an excellent substitute for chemical control. According to some investigations, grafting the commercial varieties on resistant rootstocks results in higher yield as well as the better quality. In addition to obtain higher product quality and optimize plant growth, disease management can be achieve by minimum application of pesticides.

Moslemkhani K. & Mozafari J. 2016. Management of bacterial wilt disease of potato by health assay of seed tubers. Plant Pathology Science 5(1): 62-75.
Ralstonia solanacearum is an important phytopathogen which reduces quantity and quality of potato. Due to its wide distribution and broad host range and in soil of different regions through irrigation water or latent infected tubers. It is generally difficult to control the damage of this bacterium. It has widely distributed in most of potato growing regions of Iran and by causing wilt and brown rot disease of potato, is a serious treat for cultivation of this crop in the country. Providing and sowing the healthy and certificated seed tubers is the most effective method of controlling the disease. For a successful strategy of disease management, a clear understanding of mode of disease distribution and epidemiology of causal agent is necessary. In this paper, recent scientific findings on this disease are described and new methods of bacterium detection and health assay of seed tubers are introduced.

Kamgar, A. & Ketabchi, S. (2023). The effect of three biofertilizers on growth indices of tomato and severity of bacterial wilt disease. Plant Pathology Science 12(1), 105-112.
Introduction: Bacterial wilt caused by Ralstonia solanacearum is one of the major diseases of tomato in the world. Today, new methods based on the use of biological products for the management of plant diseases have been considered to reduce the consumption of chemical toxins and damage to the environment, to provide an organic product for consumers. Materials and Methods: The effect of three biofertilizers: Nitro Kara (containing several nitrogen-fixing bacteria), effective microorganisms (EM®: containing several species of yeasts and bacteria), and compost on tomato growth indices and severity of bacterial wilt disease were evaluated in a completely randomized design in greenhouse conditions. Results: Analysis of variance showed that, these three bio-fertilizers had significant effect on increasing tomato growth indices, but did not significantly reduce the disease severity. Compost among them had the greatest effect on tomato growth indices even in the presence of the pathogen. Conclusion: Compost can be considered as an improvement factor for tomato growth indices in the management program of bacterial wilt disease.

Abstract
Rastgou, M., & Honarvar, S. (2024). Application of phages for biological control of plants pathogenic bacteria. Plant Pathology Science, 13(1),55-64.
Pathogenic bacteria are one of the most important factors in reducing the yield of plant products. In the past, the management of these pathogens was limited to the use of antibacterial compounds or resistance inducers, but with the discovery of bacteriophages in recent decades, attention to their use has increased. Bacteriophages or phages are viruses that specifically affect bacterial cells. Currently, hundreds of bacteriophages have been isolated and tested against plant pathogenic bacteria, and there are still many more that need to be investigated. This approach requires special protocols to identify new phages, understand the emergence of phage-resistant clones and the infectivity of other bacterial species. Phage therapy or the use of phages to biological control plant pathogenic bacteria due to its cheapness, very high specificity of phages against bacteria, no negative effect on humans or animals, and no environmental pollution, as a suitable method to control these pathogens can be considered.
