In vitro analyzing the antagonistic activity of seventy native bacterial isolates towards plant tumorigenic Agrobacterium tumefaciens resulted in a selection of eight potential biocontrol agents. These isolates were screened for their antagonistic effect in vitro as well as their efficacy in reducing gall formation in planta.

The environmental pollution and risk of resistance development in the pathogen by the use of chemical pesticide makes necessary to use biological agents. However the major limitations to utilize biological agents are the inconsistency, unreliable efficacy and short shelf life of the living entities used in the formulation. In this context an experiment was conducted to formulate four bacterial bio-agents viz., Bacillus subtilis-KK-9A, Brevibacillus borstelensis-BK-6, Brevibacillus sp-PM-2A and Lysinibacillus xylanilyticusVK-6B and consortium of them.

Biological control is considered as new efficient method that becomes widely used for controlling plant parasitic nematodes, as aim to decrease the extent of environment degradation and the effect of the excessive toxic nematicides. So, this study was done to investigate the role of some bacterial genera as biocontrol agent against Meloidogyne incognita.

An experiment was carried out to study the interaction of root knot nematode, Meloidogyne incognita, Paecilomyces lilacinus, Pochonia chlamydosporia, Trichoderma viride, Bacillus subtilis and Pseudomonas fluorescence on the growth of black gram. This study was done to investigate the role of some bacterial genera as biocontrol agent against Meloidogyne incognita. Paecilomyces lilacinus significantly increased the growth parameters of the black gram viz.

The phylloplane and rhizosphere microbes of rose cv. Edward was isolated and nine bacteria were selected to observe their antagonistic efficacy against Diplocarpon rosae causing blackspot disease in rose. The per cent inhibition of mycelial growth of the fungi by bacterial isolates was observed. The bacterial isolates PB1 and PB2 recorded 100 per cent inhibition followed by SB1, PB2 and SB2 isolates.

Bacterial blight is a destructive disease of rice causes 20-50% yield losses in conducive conditions. In this paper a review on the occurrence and spread of the disease, about the pathogen, its races and strains, its survival, mode of infection and transmission, different management approaches and potential role of P. fluorescens in suppression of the pathogen has been carried out. From the laboratory and field assays it is evidenced that P. fluorescens is an effective bioagent against X. oryzae pv. oryzae. The integration of micronutrient with P.

Compatibility of biocontrol agents viz., Trichoderma viride, T. harzianum and P. fluorescens were studied with four Fungicides viz., Thiram @0.3%, Carbendazim @0.1%, Captan @0.3%, fosetyl AL @0.2%, in favour of tolerance to fungicides. It was indicated that radial growth of fungal biocontrol agent Trichoderma viride was significantly inhibited (100%) with Thiram (0.3%) and Carbendazim (0.1%). Growth of T. harzianum was also 100 per cent inhibited with Carbendazim (0.1%). Whereas, both fungal biocontrol agents had recorded compatible with Fosetyl AL (0.2%), which have less (57.59% and 1.

The compatibility of bacterial biocontrol agent Bacillus subtilis was assessed with commonly used chemical fungicides viz., Carbendazim, Mancozeb, MetalaxylMZ, Wettable sulpher, Hexaconazole, Difenconazole, Tebuconazole and Kresoxim methyl. The compatibility was assessed at different concentrations and the concentration of 50, 100, 250, 500, 1000, 2000, 3000 and 5000 mg/lit for solid formulation fungicides and µl/lit for liquid formulation fungicides respectively.

Damping off caused by Pythium aphanidermatum is one of the destructive diseases in chilli (Capsicum annuum L.) worldwide. The present study was carried in vitro conditions to assess the possible use of antagonists (biocontrol agents) in field conditions. Trichoderma viride, Trichoderma harzianum, Pseudomonas flourescens and Bacillus subtilis were evaluated for bio- assay study by production of volatile metabolites.

Plant diseases have a major adverse effect on the crop yield and these can controlled by the biological approach by using PGPRs. Mustard crop suffers due to the increased number of abiotic and biotic stressors which affects its growth and yield. Now a day’s PGPR are being widely used worldwide, due to their eco-friendly nature and is considered as traditional agricultural technique. Keeping in view theabove problem, the present study has been conducted to explore the biocontrol agents along with their Plant Growth Promoting activities.

Alternaria leaf blight of tomato caused by Alternaria solani is a soil inhabiting and airborne pathogen responsible for considerable loss in tomato production. In the absence of resistant cultivars, the use of fungicides and biocontrol agents to control the disease is one exercise training. When there is an epidemic outbreak for some reason, perhaps the use of fungicides are one of the best options available. These fungicides must be used judiciously according to the need, type of body involved and availability of new fungicides.

The aim of study was development of industrially and agriculturally important bacterial strains which produces antimicrobial protease. It is a kind of study that tends to contribute the potential Pseudomonas strains that may be helpful as plant growth promoting, biocontrol agent and may be used for the production of antimicrobial protease at industrial level. In the present study we have tried to isolate the fluorescent Pseudomonas sp. from three medicinal plants i.e., Achyranthus aspera, Elaegnus umbellate and Heracleum candicans. Three strains were isolated i.e.
