The present study describes physicochemical characterization and rhizosphere soil mycoflora in the field of onion white rot caused by Sclerotium cepivorum. Soil fungi in onion infected field need to improve knowledge of diversity of fungi associated with white rot of onion. Infected rhizosphere soil, sixteen physicochemical parameters were analysed. It founds alkaline pH but EC, N, Ca, Na, B, S and Mo contents were found least whereas OC, P, K, Zn and Cu high in infected soil as compared to standard range. | Physicochemical characterization and papulation dynamics of mycoflora in infected rhizosphere soil of onion white rot caused by Sclerotium cepivorum
