“…For instances, nonpathogenic strains of Streptomyces sp. are known to control scab of potato (Solanum tuberosum L.) caused by Streptomyces scabies (Neeno-Eckwall and Schottel, 1999). The antagonistic activity of Streptomyces is likely to be associated with the production of extracellular hydrolytic enzymes and secondary antifungal metabolites.…”

Agriculture is a complex network of interactions of plants with microorganisms. There is a growing demand for ecologically compatible, environment friendly technique in agriculture that might be able to provide adequate supply of nutrients for the increasing human populations through improvement of the quality and quantity of agricultural products. Under the changing climatic scenario of global fluxes of the key biogenic greenhouse gases (carbon dioxide, methane, and nitrous oxide), and some other environmental problems, the application of beneficial microorganisms in agriculture would serve as an important alternative gateway to some of the traditional agricultural techniques. Microorganisms of agricultural importance represent key ecological strategy for integrated management practices such as nutrient management, disease, and pest management in order to reduce the use of chemicals in agriculture as well to improve cultivar performance. The present review is intended to focus on the emergence of agriculturally important microorganisms to develop an ideal agricultural system through efficient utilization of nutrients and recycling of energy and thereby to preserve the natural ecosystem resources under climate change. The progress to date in using the beneficial microflora in a variety of applications related to agriculture along with key mechanism of action is also discussed in this review.

Aims: The primary objective of these experiments was to reduce pathogenicity and virulence of endemic soil pathogenic Streptomyces strains that cause potato common scab (CS) using nonpathogenic Streptomyces strains to suppress CS in a field situation. Methods and Results: Nonpathogenic Streptomyces strains that had shown potential for mitigating CS in greenhouse assays were used in Michigan and Pennsylvania fields known to have high CS disease pressure. Five biocontrol (BC) strains and three potato cultivars were used in 2009, and three BC strains and three cultivars were used in 2010 in each location. The effects of BC strains on CS disease incidence and severity differed between locations, years and potato cultivars. When overall means of individual BC treatments were compared with nontreated controls, CS incidence and severity were decreased by all BC strains in PA2009, PA2010 and MI2010, particularly in cultivar 'Yukon Gold' in MI. Biocontrol treatments also significantly shifted the proportions of superficial, raised and pitted lesion types in some cultivar/ biocontrol treatment combinations. Conclusions: All BC strains significantly reduced CS incidence and severity on 'Yukon Gold' in three of four trials, and one BC strain significantly improved the lesion severity profile in cultivar 'Atlantic'. No BC strain significantly reduced CS incidence and severity on all potato cultivars in the different years and locations. Significance and Impact of the Study: Several nonpathogenic Streptomyces strains showed potential to reduce CS incidence and severity on two important potato-chipping cultivars in the field. These results can be further applied to reduce CS disease severity in potatoes.

“…Scab suppressive soils have been identified and it has been found that the lenticels on these tubers are colonised by Streptomyces . Suppressive strains of Streptomyces isolated from a naturally scab suppressive soil produced antibiotics that inhibited S. scabies in vitro (Neeno-Eckwall and Schottel, 1999).…”
