Abstract

Genetic Diversity and Biological Control of Rhizoctonia solani Associated with Root Rot of Soybean in Assiut Governorate, Egypt

Rhizoctonia solani Kühn (Teleomorph: Thanatephorus cucumeris) is considered one of the most destructive soil and seed-borne plant pathogens infecting various agricultural crops including soybean. Study on genetic diversity of the pathogen can provide information on its behavior in field as well as its pathogenicity. We isolated five isolates from R. solani and tested that for pathogenicity test our results indicate that, all tested isolates were able to infect soybean plants causing root rot with different degrees of virulence. Isolates R5 showed the highest pathogenic capability and gave high significantly root rot rating.
