Fusarium wilt is a soil-borne disease, which negatively affects the lentil crop widespread in India and affecting the lentil crop productivity. So the present study was conducted to evaluate the efficacy of bioagents against wilt pathogen Fusarium oxysporum f.sp.lentis of lentil crop through antagonistic activity. Rhizospheric strains were isolated from wilt affected lentil plant in different regions of Eastern UP like Faizabad, Mau, Varanasi, Ghazipur. A total of 20 bacterial strains were isolated and tested for antagonistic activity by co-culture m

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.

Fusarium oxysporum f. sp. ciceri is one of the most destructive pathogen, causing wilt disease in chickpea and thereby inflicting accountable quantitative (48.29%) as well as qualitative losses. All the six fungal and two bacterial bioagents tested in vitro, exhibited significant mycelial growth inhibition of Fusarium oxysporum f. sp. ciceri. However, Trichoderma viride recorded significantly highest mycelial growth inhibition (75.55%), followed by Trichoderma harzianum (73.77%) Trichoderma koningii (71.88%) and Pseudomonas fluorescens (43.77%).

Biotic and abiotic stresses are major constraints in the production of groundnut. Among biotic stresses apart from bacterial and viral diseases, many fungal diseases are of economic importance. The major fungal diseases are Early leaf spot (Cercospora arachidicola), Late leaf spot (Cercosporidium personatum), Rust (Puccinia arachidis), Botrytis blight (Botrytis cinera), Aflarot/Yellow mould (Aspergillus flavus), Damping off (Pythium spp.

Efficacy of three potential microbial bioagents, viz. Trichoderma viride, Bacillus thuringiensis, Pseudomonas fluorescens were evaluated against bacterial wilt of lettuce under hydroponic culture system. The microbial bioagents were tested in vitro for their antagonistic properties against Ralstonia solanacearum, the causal agent of bacterial disease in lettuce. Bioagents applied alone or as consortia, significantly reduced bacterial wilt pathogen in vitro producing varying sizes of inhibition zones in TTC medium.

Brinjal is one of the important vegetable crop cultivated widely in India. It is susceptible to many diseases like sclerotium rot/wilt, verticillium wilt, fusarium wilt and bacterial wilt and it is being attacked by several diseases of fungi and bacteria. The collar rot/wilt disease caused by Sclerotium rolfsii is an important constraint in brinjal production. Hence, an in vivo study was conducted to evaluate the bio efficacy of antagonistic bioagents and fungicide chemicals against root rot/wilt disease of Brinjal at College of Agriculture, Bheemrayangudi during 2011–2012.

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 potent native bioagents isolated from tomato rhizosphere have high antagonistic potential against Phytophthora infestans. Molecular characterization of fungal isolates (T-11 and T-14) was performed by using Internal Transcribed Spacer (ITS) region of 18S rRNA sequence. The sequence analyses of two isolates (MK928414 and MK928417), showed 100% similarity with Trichoderma asperellum during BLAST analysis. The phylogeny tree constructed by using sequence analysis showed the formation of cluster along with T. asperellum and both the isolates were identified as T. asperellum.

An experiment was conducted to study the bio-efficacy of native bioagent and biofertilizer for the management of root-knot nematode Meloidogyne incognita infecting black gram Vigna mungo. For this the bioagents, Pseudomonas fluorescens, Bacillus megaterium, Pochonia chlamydosporia and Purpureocillium lilacinum and biofertilizers like Azotobacter sp. and Rhizobium sp. were screened against M. incognita by using seed treatment under pot condition.
