The inhibitory effects of volatile and non-volatile compounds on different soil borne fungal pathogens were observed (Sabaratnam and Traquair 2002;Elango et al 2015). The results of the present study demonstrate that non-volatile substances produced by Streptomyces strains have a significant effect on the mycelial growth of pathogen.…”

“…Previous studies have illustrated that Streptomyces spp. effectively suppressed red root-rot disease of tea plants and red rust disease caused by Poria hypolateritia and Cephaleuros parasiticus, respectively (Elango et al 2015). Of the five Streptomyces strains tested in the greenhouse, the highest degree of increment of plant biomass was observed by strains KS112 and KS55 (Table 4).…”

Abstract:In this study, about 112 isolates of Streptomyces were isolated from chickpea rhizospheric soils. Among the isolated strains, five showed strong inhibitory effects against chickpea Fusarium wilt caused by Fusarium oxysporum f. sp. ciceris in vitro using plate assay and selected for further studies. The selected strains were identified as Streptomyces spp. based on morphological and biochemical characterization as well as 16S rDNA sequences analysis. Our results assigned them to strains related to genus of Streptomyces.In vitro, antagonistic effects of Streptomyces strains against the disease were evaluated through the dual-culture method, volatile and non-volatile metabolites, siderophore, protease and chitinase production. All bacterial strains inhibited mycelial growth of the pathogen ranging from 26 to 44.2% in dual culture assay. The non-volatile extract of five of the Streptomyces strains inhibited more than 50% growth of the pathogen, whereas volatile compounds were less effective on mycelial growth inhibition (20.2 to 33.4%). The ability of the biocontrol agents to produce siderophore and protease were varied, whereas, production of chitinase was detected for all strains. Results of the greenhouse assay indicated that all biocontrol agents reduced disease severity (ranging from 38.7 to 54.8%).Accordingly, strain KS62 showed higher control efficacy (54.8%). In addition, the biomass of chickpea plants (plant height and dry weight) significantly increased in plants treated with Streptomyces strains compared to non-bacterized control. The results of this study showed that it may be possible to manage chickpea Fusarium wilt disease effectively by using Streptomyces species, as biocontrol agents. Therefore, evaluating their efficiency under field conditions is needed.

“…Streptomyces are filamentous Grampositive soil bacteria with a high G + C content and they are well known for their ability as biological control agent (El-Tarabily 2008;Caraveo et al 2014;Soltani Nejad et al 2015b). In a research, Streptomyces griseus and Streptomyces lydicus along with Bacillus subtilis and Trichoderma harzianum were used for the control of red root rot disease of tea plants caused by Poria hypolateritia in field condition (Elango et al 2015).

Black root rot, caused by Fusarium solani f.sp. pisi, is a devastating soil‐borne disease in chickpea in Iran with no effective control measures. With the aim of finding applicable biocontrol agents to alleviate the malady, isolates of Actinomycetes isolated from soil and their antagonistic effect against F. solani f.sp. pisi were evaluated both in vitro and in vivo. More than 100 Actinomycetes isolates were screened for their antifungal activities against the pathogen. The most active isolates were evaluated in greenhouse for their biocontrol performance. Based on the results of dual cultures in screening evaluations, the size of inhibition zone of fungal growth, and the most effective antagonist isolates (S3, S12 and S40) were selected for further studies. Identity of active isolates was determined, in this regard, 16S rDNA of isolates were amplified using universal bacterial primers FD1 and RP2. The PCR products were purified and sequenced. Sequence analysis of 16S rDNA was then performed using NCBI BLAST method. Comparison of the near full length 16S rRNA sequence of isolates to GenBank sequences demonstrated that isolates S3 and S12 were most similar to Streptomyces antibioticus, while isolate S40 was most similar to Streptomyces peruviensis. Biocontrol studies of these isolates in control of the disease in greenhouse significantly decreased the disease severity. Actinomycetes isolate S12 demonstrated the greatest effect in reducing disease than the other two. Results of this research are at preliminary stage for developing biocontrol agents. These data can be utilized as a platform for future studies with the aim of commercializing these biocontrol products and hoping to step towards sustainable agriculture.

Microbial inoculants for controlling soil pathogens are an environmentally sustainable approach for attaining agricultural intensification. Charcoal root rot pathogens might threaten global food security and degrade prime agricultural lands. Microbial antagonists to control charcoal root disease were not properly studied with reference to physiological and photochemical basis. This research was aimed to examine the impact of newly isolated microbial biocontrol agents (MBCAs) on growth and photosynthetic efficiency (photosystem II) in pathogen (Macrophomina phaseolina)‐infected plants. The MBCAs (Purpureocillium lilacinum and Aspergillus terreus) were isolated and seeds were coated to improve soil fertility and resilience of agricultural lands. Both MBCAs inhibited the colonization of pathogenic fungus around the roots of host plants. Decline in growth traits was observed due to the detrimental impacts of root rot disease on growth parameters compared with plants treated with M. phaseolina. However, the growth of corn plants in both soils with and without M. phaseolina infestations was substantially improved by treating corn seeds with P. lilacinum and A. terreus. The pathogen drastically reduced the distinct parameters of photosystem II of photosynthesis. However, applying P. lilacinum and A. terreus significantly improved the total performance index (PItot), size, and the number of active reaction centers of photosystem II (Fv/Fo), electron transport rate, electron trapping per absorption (TRO/ABS), electron transport per absorption (ETO/ABS), electron transport per trapping (ETO/TRO), and the efficiency of light reaction (φEo) but downregulates nonphotochemical quenching (NPQ). Our study demonstrates that microbial antagonists offer a more effective, ecofriendly alternative to improve the land to sustainable agriculture.
