Chemical pesticides have always been seen as an effective methodology in control of plant pathogens in the past, but greater environment-consciousness is pushing the demand for minimum use of harmful chemical inputs. Moreover, a pesticide does not provide complete or lasting defense against soil-borne plant pathogens besides posing great threat to our lives (Johansson et al., 2004). This has led to advanced research into bio-control methods, which are beneficial for farmers who are not very economically well-off and for sustainable agricultural practices, which will benefit our environment and biodiversity as a whole. The biological control of plant pathogens by using arbuscular mycorrhizal fungi in providing resistance against various plant pathogens have been well-documented (Singh et al., 2000; Declerck et al., 2002; Ludwig-Muller, 2004; Whipps, 2004).Groundnut (A. hypogaea L.) is important as a chief oilseed crop in the Indian subcontinent. Several soil-borne plant pathogens attack groundnut plants during their growth. Among various pathogens, fungal pathogen M. phaseolina Tassi (Goid.) causes severe charcoal root-rot disease, which may assume huge economic proportions. Because of being soil-borne in nature, it remains a difficult pathogen to eradicate completely and chemical inputs are already considered both hazardous to the environment as well as costly. M. phaseolina is distributed worldwide and prevalent mainly in areas with high temperature and low rainfall (Raut and Bhombe, 1984). The main objective of this study was to evaluate the effectiveness of mycorrhizal inoculation against M. phaseolina under field conditions.
