Abstract
The possible role of biochar and its interaction with the fungus Glomus mosseae in promoting the growth of the common bean plant, Phaseolus vulgaris L., grown under biological stress with the pathogenic fungus, Rhizoctonia solani was investigated. The results showed that the addition of biochar and the treatment with mycorrhizal fungus, and the interaction between them, led to a significant reduction in the seedling mortality and the severity of root rot disease of the common bean plant. The results obtained showed that the mycorrhizal traits, which included infection rate, severity of infection, and number of spores, were affected by the presence of the pathogenic fungus, as all the studied mycorrhizal traits decreased, compared to the treatment of the mycorrhizal fungus in the absence of the root rot fungus. The results obtained also showed that the decrease in the disease had a positive effect on the vegetative and root plant growth and nutrients content. The results obtained encourages the application of biochar as an alternative to chemical pesticides for the control of common bean root rot.
