Isolation and characterisation of rhizosphere bacteria active against Meloidogyne incognita, Phytophthora nicotianae and the root knot-black shank complex in tobacco

摘要

BACKGROUNDThe use of dually antagonistic bacteria (DAB) as alternatives to chemicals for biological control of disease complexes has received little attention. In this study targeting the Meloidogyne incognita-Phytophthora nicotianae complex, DAB from the tobacco rhizosphere were identified and screened against the diseases caused by one or both pathogens in tobacco.
