“…This could be due to their antagonistic effect as reported by Gasoni et al [7], Nelsson [9], Ehteshamul-Shaque and Ghaffar [10], Zheng and Sinclair [11], Lewis and Lumsent [12], Jensen et al [13] and Santamarina and Joseph [14]. These results also were reported by Chen et al [1], Liu et al [30] and Pietrse et al [31] who showed that (PGPR) has been investigate as a possible practical way to use induced resistance to fungal pathogens in various crops.…”

“…Nelsson [9] reported that Trichoderma spp., are specific biocontrol agents against fungal pathogens (from Pythium to Rhizoctonia) according to the type of antibiotic produced. Under field conditions, Ehteshamul and Ghaffar [10] observed the antagonistic rhizobia and bradirhizobia used as seed dressing or soil drench reduced infection of Rhizoctoia solani in both leguminous and no leguminous plants. Zheng and Sinclair [11] showed that Bacillus megaterium is a potential bacterial biocontrol agent against Rhizoctonia solani.…”

Some biofertilizers agents i.e. Rhizobium leguminosarum var. fabae, Bacillus megaterium var., phosphaticum and Trichoderma harizianum play important roles in enhancing the plant growth and controlling several diseases i. e. root rot and stem canker disease. In this work, under greenhouse conditions, Rhizoctonia solani caused dampingoff and death of all faba bean seedlings, however the three tested microorganisms resulted good biocontol role against the pathogenic fungus and the application of T. harizianum gave the best result in this trend. The treatment of T. harizianum and R. leguminosarum var. fabae to the soil infested with Rhizoctonia solani showed significant increase in leaves number of faba bean plants compared with the untreated plants or which treated plants or which treated with Bacillus megaterium var., phosphaticum after 40 days from planting. Application of T. harizianum and R. leguminosarum var. fabae gave the best plant growth while the presence of the pathogenic fungus showed significant decrease in fresh weight, dry weight and nodules number on roots of faba bean plants. Also, polyphenols and antioxidants contents in the shoots and roots were decreased in the presence of the pathogen compared with the untreated plants. Application of R. leguminosarum resulted significant increase in the roots and shoots total nitrogen and protein.

“…On the basis of these results, a mode of action of antifungal activity in culture filtrate is through production of lytic enzymes and antifungal metabolites by B. amyloliquefaciens Y1 in media. Ehtesmul -Haque and Ghaffar (1993) reported that antifungal activity by many antagonistic bacteria is possible through by production of secondary metabolites.…”

This study was performed to investigate thermophilic bacteria from soil having broad antifungal spectrum against Rhizoctonia solani, Colletotrichum gloeosporioides, Phytophthora capsici, Fusarium oxysporum f.sp. lycopersici, and Botrytis cinerea. One isolate selected could resist heat shock of 60°C for one hour, and had broad antifungal activity in dual culture assay against all tested fungal pathogens and was identified as Bacillus amyloliquefaciens Y1 using 16S rRNA gene sequence. Further investigation for antifungal activity of bacterial culture filtrate (BCF) and butanol crude extract (BCE) of various concentrations showed broad spectrum antifungal activity and fungal growth inhibition significantly increased with increasing concentration with highest growth inhibition of 100% against R. solani with 50% BCF and 11 mm of zone of inhibition against R. solani with 4 mg BCE concentration. Treatment of butanol crude extract resulted in deformation, lysis or degradation of C. gloeosporioides and P. capsici hyphae. Furthermore, B. amyloliquefaciens Y1 produced volatile compounds inhibiting growth of R. solani (70%), C. gloeosporioides (65%) and P. capsici (65-70%) when tested in volatile assay. The results from the study suggest that B. amyloliquefaciens Y1 could be a biocontrol candidate to control fungal diseases in crops.

“…Application of rhizobial isolates as seed coating or as soil drench reduced disease incidence of M. phaseolina, R. solani and Fusarium spp. in okra plants [58]. Deshwal et al [42] reported that several rhizobial and bradyrhizobial isolates can effectively suppress the growth of Macrophomina phaseolina causing charcoal rot of ground nut.…”

Development of Mesorhizobium ciceri-Based Biofilms and Analyses of Their Antifungal and Plant Growth Promoting Activity in Chickpea Challenged by Fusarium Wilt

Biofilmed biofertilizers have emerged as a new improved inoculant technology to provide efficient nutrient and pest management and sustain soil fertility. In this investigation, development of a Trichoderma viride-Mesorhizobium ciceri biofilmed inoculant was undertaken, which we hypothesized, would possess more effective biological nitrogen fixing ability and plant growth promoting properties. As a novel attempt, we selected Mesorhizobium ciceri spp. with good antifungal attributes with the assumption that such inoculants could also serve as biocontrol agents. These biofilms exhibited significant enhancement in several plant growth promoting attributes, including 13-21 % increase in seed germination, production of ammonia, IAA and more than onefold to twofold enhancement in phosphate solubilisation, when compared to their individual partners. Enhancement of 10-11 % in antifungal activity against Fusarium oxysporum f. sp. ciceri was also recorded, over the respective M. ciceri counterparts. The effect of biofilms and the M. ciceri cultures individual on growth parameters of chickpea under pathogen challenged soil illustrated that the biofilms performed at par with the M. ciceri strains for most plant biometrical and disease related attributes. Elicitation of defense related enzymes like L-phenylalanine ammonia lyase, peroxidase and polyphenol oxidase was higher in M. ciceri/biofilm treated plants as compared to uninoculated plants under pathogen challenged soil. Further work on the signalling mechanisms among the partners and their tripartite interactions with host plant is envisaged in future studies.
