Bacteria are generally the predominant initial inhabitants of newly expanded leaves, while yeast and filamentous Fungi dominate later in the growing season (Srivastava and Shalini, 2008). The extraordinary use of chemical fungicides resulted in environmental pollution and ill health to biotic community as a whole. Therefore biological method of plant disease management seems to be a better alternative to chemical fungicides in managing the ISSN: 2319-7706 Volume 2 Number 1 (2013) pp. 59 65 
This research was aimed to isolate and identify microbes which antagonistic against Fusarium oxysporum, the causative agent of vascular wilt in watermelon plants. The antagonistic microbes were
In vitro activity to promote plant growth and biological control of rhizobacteria isolated from bermuda grass ruderal
Although Cm0711 was significantly higher than Pm0710 in most of the properties analyzed, the two bacteria have potential to be used as bio-inoculants; however, before validation must be done in vivo.
Bioprospecting of elite plant growth-promoting bacteria for the maize crop
The results highlight the potential of bacterial genera little explored as maize PGPB but indicate the need to investigate their interactions with different plant genotypes.

With a growing dominance of nematodes in India, Meloidogyne javanica is considered as an important limiting factor in a yield reduction of brinjal crop.
Selection and Characterization Of Siderophore-Producing Rhizobacteria and Potential Antagonistic Activity Toward Ralstonia Solanacearum
Among 29 isolates producing siderophore and having negative result on hypersensitivity reaction, two isolates provided the widest diameter of inhibition zone toward R. solanacearum.
Enumeration and Identification of Rhizospheric Microorganisms of Sugarcane Variety CO 421 in Kibos, Kisumu County, Kenya
The sugarcane Variety CO 421 was selected for this study because it is widely adapted and grown in allugarcane growing areas of Kenya and was selected based on their morphological, biochemical characters, taxonomic guides and standard procedures.
Plant Growth Promoting (PGP) Attributes of Stress Tolerant Rhizobial Isolates from Root Nodules of Pigeon Pea [Cajanus cajan (L.) Millspaugh] Growing in Haryana, India
Pigeon pea (Cajanus cajan (L.) Millspaugh) is one of the important pulse crop and a very popular food in developing tropical countries and inoculation of pulse crops with effective rhizobium strains prior to sowing is a recommended practice as it improves nodulation and nitrogen fixation, which in turn is translated into enhanced growth and grain yield.
On the potential of Bacillus aryabhattai KMT-4 against Meloidogyne javanica
Background Nematodes ( Meloidogyne spp.) are a major reason behind the global crop yield reduction. The bacterial strain KMT-4 was isolated from nematode-affected tomato ( Solanum lycopersicum )
Simple and Effective Method for Development of Longer Shelf Life Liquid Formulation with Azospirillum brasilense strain Asp-7
Liquid formulation is an upcoming technology to overcome the limitations associated with carrier based formulation. In our study a total of nine Azospirillum spp. were isolated, screened for plant


Antifungal Activity of Pseudomonas fluorescens Against Different Plant Pathogenic Fungi
Out of the five strains studied, the best result was shown by A-5, which showed almost complete inhibition against pathogenic fungi such as Curvularia lunata.
Screening of free-living rhizospheric bacteria for their multiple plant growth promoting activities.
On the basis of multiple plant growth promoting activities, eleven bacterial isolates were evaluated for their quantitative IAA production, and broad-spectrum antifungal activity on Muller-Hinton medium against Aspergillus, one or more species of Fusarium and Rhizoctonia bataticola.
Antagonism of Bacillus spp. Isolated from Marine Biofilms Against Terrestrial Phytopathogenic Fungi
Overall antagonistic assays showed differential susceptibility among the pathogens as a function of the type of culture media and time of colonization, and F. oxysporum was the most resistant fungus while the most sensitive was C. gloeosporioides ATCC 42374.
Isolation of Bacteria with Antifungal Activity against the Phytopathogenic Fungi Stenocarpella maydis and Stenocarpella macrospora
The bacteria described in this work have the potential to be used in the control of white ear rot disease because they did not show a cytotoxicity effect against brine shrimp and inhibited germination of conidia.
Characterization and Antagonistic Activities of Metabolite Produced by Pseudomonas Aeruginosa Sha8
The antagonistic activities of Bacillus firmus and Pseudomonas aeruginosa which were isolated from rhizosphere field of Triticum sativum cultivated in El-Sharkia governorate, Egypt; were studied against 13 fungal isolates and the antifungal activity was remarkable at 100°C for 30 mins.
Biological Control of Sclerotium rolfsii, Causing Stem Rot of Groundnut by Pseudomonas cf. monteilii 9
In an attempt to develop effective biocontrol system for management of stem rot disease caused by Sclerotium rolfsii in groundnut, 11 Pseudomonas spp . isolated from rhizospheric soil, were evaluated
Antifungal activity of Bacillus subtilis 355 against wood-surface contaminant fungi
A strain of Bacillus subtilis was examined for antifungal activity against phytopathogenic and wood-surface contaminant fungi and the presence of at least two active compounds against the blue-stain fungus Cladosporium cucumerinum was revealed.
Antifungal activity of Bacillus sp. E164 against Bipolaris sorokiniana.
Control exerted by Bacillus E164 over B. sorokiniana isolates was relevant in vitro, nevertheless the influence and importance of the metabolites produced must be elucidated for the application in vivo.
Effect of iron and growth inhibitors on siderophores production by Pseudomonas fluorescens
The ability of Pseudomonas to grow and to produce siderophores is dependent on the iron content and the type of carbon sources in the medium. Under conditions of low-iron concentration the
