“…While the host ranges of R. solanacearum race 4 is restricted to edible ginger (Duressa, 2018). GBW disease was first reported from the Benchmaji zone of Southern Ethiopia and distributed to the nearby areas of Wolayta and Sheka zones with 22.3 and 67% yield loss, respectively (Bekelle et al, 2016). Yield loss can vary across agroecologies, weather conditions, climate, soil type, cropping pattern, and pathogen strains.…”

Horticultural crops that can solve food insecurity problems are essential commodities. The availability of diverse soil, favorable climatic conditions, and comfortable agro-ecological zones in Ethiopia provide ample opportunities to produce them. However, the success of production has been challenged by biotic and biotic factors. From which, diseases caused by bacterial pathogens are the current globally emerging and re-emerging threats of crop production. Hence, this review is crucial to accentuating newly emerged and re-emerged bacterial diseases that cause great economic damage to essential horticultural crops in the country. Many African countries are experiencing outbreaks and the potential for these bacterial pathogens to emerge. Among these, many hosts killing and yield loss problems due to ginger bacterial wilt (Ralstonia solanacearum), bacterial blight of coffee (Pseudomonas syringae), banana, and enset wilt (Xanthomonas campestris) diseases result in > 50% yield reduction. Various factors like introducing new types within a species, homogeneity of resistant plant varieties, hybridization within pathogen species, and introducing an arthropod vector to be "emergence" or increase in importance within that environment to favor their distribution. Once they are established, bacterial disease management is so complex both by chemical and biological means and is restrained primarily by preventive measures such as hygiene, healthy planting materials, good cultural practices, and avoidance. The potential use of community heterogeneity/plant population/is an exciting and controversial option to reduce the risk of disease emergence. In all, this article is crucial to offer detailed insight on some bacterial diseases that threaten the production of economically essential horticultural crops.

Background: Bacterial wilt incited by Ralstonia solanacearum is the most important disease affecting ginger production in southwestern Ethiopia. The unavailability of disease-free planting materials, resistant cultivars, and effective chemical compounds are the key constraints in managing the disease. Objective: The study was initiated to determine the effect of integrated management methods on bacterial wilt disease and yield loss of ginger through combining hot water, bio-fumigation, soil-solarization and chemical pesticides. Methods: A total of seven treatment combinations comprising hot water, bio-fumigation, soil-solarization, Mancozeb, and bleaching powder were tested in a randomized complete block design in three replications. Data on disease incidence, growth, yield, and yield components were recorded from randomly selected plants. Results: The use of Mancozeb for seed socking and soil drenching combined with bio-fumigation and soil-solarization reduced the incidence of bacterial wilt by 63.3% and enhanced the rhizome yield by 66.8%. Rhizome and soil treatment using bleaching powder along with soil bio-fumigation also reduced the disease incidence by 38.9% and increased ginger yield by 61.5%. It also provided the highest (6678.7%) marginal rate of return of any treatment combination tested in the experiment. Disease incidence was highly significantly and inversely (r= -0.98**) correlated with rhizome yield. The regression slope estimated that 83.4% of ginger yield loss was associated with bacterial wilt disease. Conclusion: A combined application of Mancozeb, bio-fumigation and soil-solarization can be used to control ginger bacterial wilt. Alternatively, bleaching powder for rhizome and soil treatment in conjunction with bio-fumigation can be employed as an integrated management system against the disease.
