Utilization The Fungus of Mycorrhriza to Control Bean Root Rot Caused by Pathogenic Fungi Rhizoctonia Solani

The study was conducted for the purpose of knowing effect mycorrhizal fungus on controlling root rot disease caused by pathogenic Rhizoctonia solani, field experiment included four treatments and each treatment had five replicates, were as follows (Control, Mycorrhiza, Rhizoctonia, Rhizoctonia), where percentage infection with (0.00, 0.00, 96.91, 63.58), respectively. while growth indicators studied, including plant height (106.24 , 112.58, 81.64 101,72 ) respectively average number leaves above (24.98 27.14 17.50 26.16 length (23.40 30.32 10.32 28.42 wet weight ( 4.17 6.96 0.98 5.13 superior in all studied indicators, followed + rhizoctonia, pathogen recorded lowest There significant differences at a level 0.05% between
