“…Species from more than 44 plant families have been identified by Hayward (1991) and more hosts are being recognised and described. Some of the reports included onion, Allium cepa (Girard et al, 1992); custard apple, Annona spp., (Mayers and Hutton, 1987); florist geranium, Pelagornium hortorum (Strider, 1981); strawberry, Fragaria spp., (Hsu, 1991) and radish, Raphanus sativus L., (Hsu, 1991), etc. Cassava is cultivated in many countries where bacterial wilt is endemic, yet the disease on this host appears to be confined to Indonesia.…”

Potato is one of the most important vegetable crops in Bangladesh which made it 7th producer in the world. This vegetable crop is affected by one of the most notorious soil borne pathogen, Ralstonia solanacearum and caused wilt symptoms in plant and brown rot in potato tuber throughout the world. The pathogen entered into the plants through different natural opening and wounds and is easily disseminated via infected biological material (seeds, vegetatively propagative materials, plants etc.), soil, contaminated irrigation water, surface water, farm equipment etc. and could survive for many years in association with alternate hosts. The bacteria is a quarantine organism being economically a serious problem for potatoes and other major crops in many tropical, subtropical and warmer areas of the world. It has an unusually wide host range including economically important crops (potato, tomato, tobacco, banana, ginger, geranium etc.) and weeds. The disease appeared as rapid and fatal wilting symptoms in the potato plants and vascular browning and/or rotting on tubers. The pathogen can be detected through the isolation of the bacteria on semi-selective TZC and/or selective SMSA (modified) media and through different biochemical tests and/or molecular test. It is a Gram-negative type bacterium, subdivided into five races based on host range and race 3 biovar III is reported in Bangladesh. Direct yield losses caused by R. solanacearum may vary 33 to 90% depending on the different factors such as cultivar, climate, soil type, cropping pattern, strain of the bacteria etc. Due to the latent infection of tuber by this organism, Bangladesh had been facing a temporary embargo on potato export which was imposed by Russia during 2014-15. But, latency and some other survival strategy of the pathogen created much more problems with disease detection, control and dispersal. The biological features of this pathogen makes it unusually successful against the traditional management practices. Therefore, the review focused on the biological abilities of R. solanacearum in relation to dispersal, survival and influences which might be important in designing effective management against the pathogen.

“…Trees grafted on A. squamosa rootstock were highly susceptible to bacterial wilt compared with trees grafted on A. cherimoya that had a good level of resistance. Annona cherimoya rootstocks provided a level of economic disease control for custard apple orchards in subtropical regions (Mayers & Hutton, 2008). The A. cherimoya cultivar White proved to have the highest resistance and grows equally well at both high and low soil temperatures producing more dry matter, which may explain why it also exhibits resistance to bacterial wilt compared with hybrid species ( A. cherimoya × A. squamosa ), A. squamosa , and A. glabra (George & Nissen, 1987b).…”

An overview of the genus Annona in the Family Annonaceae is provided in this review. The mainly neotropical family of trees and lianas has numerous commercial fruits that are eaten fresh, processed, or used as popular medicines. The family has 109 recognized genera and from 2,300 to 2,500 species. The taxonomy, morphology, and cytology of Annona spp. are discussed. The genus Annona has the most fruits of commercial importance, including the cherimoya (A. cherimola Mill.), soursop (A. muricata L.), sugar apple (A. squamosa L.), ilama (A. diversifolia Saff.), pond apple (A. glabra L.), biriba (A. mucosa Jacq. formerly Rollinia deliciosa Saff.), and hybrids such as the atemoya (A. squamosa × A. cherimola).

“…R. solanacearum biovar 3 has been described on some woody perennial hosts including cashew (Anacardium occidentale) and custard apple (Annona spp.) [12] . The reason for these highly different and heterogeneous bacterial pathogen is not obvious; nevertheless it is assumed that specific pathogenic strains for certain hosts may have evolved only in certain parts of the world and are not found elsewhere or these hosts may only be susceptible where a number of environmental factors such as temperature, rainfall, soil type, inoculums and other soil biological factors are conductive to disease expression coincide [20] .…”

Solanum melongena L. (Brinjal), quite common and popular vegetable crop grown extensively during warm weather in India and is a major source of income for the small and marginal farmers as well. The major constraint in the production of brinjal is the bacterial wilt disease caused by Ralstonia solanacearum. Crop rotation with non-host plants has not been effective, since R. solanacearum has its disseminating and survival stages in the soil. The race and strain diversity of the pathogen has made breeding for resistant cultivars ineffective. That's why study was done to isolate wilt causing bacteria Ralstonia solanacearum from the infected roots of Brinjal plant of Hadoti region and characterize the isolated bacteria through various methods. Initial cultures were grown by streaking on nutrient agar medium. After, bacterial wilt pathogen Ralstonia solanacearum was identified; it was confirmed by PCR (Polymerase chain reaction) amplification. Isolate of R. solanacearum were characterized by various DNA Markers.
