Wilt caused by Fusarium oxysporum f. sp. ricini poses a major problem in all the castor growing areas of the country. Since the soil borne disease can be effectively controlled by biocontrol agents, the present study was conducted to know the antagonistic activity of different bioagents in vitro at department of Plant Pathology, College of Agriculture, UAS, GKVK, Bengaluru during 2019-20.

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

This study, with two antagonists, two fungicides (alone and combinations) against Fusarium tomato wilt. Pot culture studies found that Average reduction of F. oxysporum f. sp. lycopersici recorded with the test fungicides and bioagent ranged from 25.81% to 72.21%, as against 00.00% in untreated control.

The soil-borne necrotrophic fungal pathogen Fusarium oxysporum f. sp. Ciceris (FOC)infects chickpeaand causes wilt in any stage of plant from seedling to podding. Owing to climate change and ever changing nature of the pathogen, no resistant host cultivar is sustaining long against this disease. Hence, root resident Aspergillus niger isolates as native mycoflora were evaluated as bioagent against the FOC because chemical control has long been discouraged due to its circulation in food chain. In this study, we established the biocontrol potential of organic acid producing A.

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.

Tomato (Lycopersicon esculentum L.) is the world’s largest vegetable crop after potato and sweet potato, belongs to family Solanaceae. It was universally treated as ―protective food‖ because of its special nutritive value. Fusarium wilt of tomato is one of the most devastating diseases, caused by Fusarium oxysporum f.sp. lycopersici. It is a soil borne pathogen which causes serious loss in tomato production and attacks plants through roots at all stages of plant growth.
