Chickpea wilt

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.

Chickpea wilt caused by F. oxysporum f. sp. ciceri is one of the most important seed and soil-borne disease in India. The study on association of the pathogen with chickpea seeds showed that the viable mycelium fragments, micro and macro-conidia of the pathogen were present on the seed surface of all susceptible and two resistant varieties/ germplasms in seed washing test. The pathogen was recovered from the untreated and sodium hypochlorite treated seeds of all susceptible varieties/ germplasms in the range of 10.67– 18.67 and 5.33–11.
