| Abstract | ||||
| Eleven isolates of Rhizoctonia solani and 15 isolates of Fusarium sp < /em>p were isolated from lentil rotted roots and crowns. All isolates of R.. solani except two (R2 and Rg) aggressively attacked lentil mostly during their seedling stages. On the other hand. three isolates of F. solani (Fll . F'2 . F,5 ). out of the 15 tested isolates showed high pathological effect at all stages of the subjected plants causing pre- and post- emergence damping-off and root rot. Isolates Rs and Re of R. solani and isolate F" of F. solani attacked six local cultivars of the lentil plants but the three Canadian cultivars tested showed great resistance. Seven fungicides showed various inhibitory effect against R. solani and F. solani in vitro, the four more effective ones (Topsln-M, Rhizolex -T. Monceren and Homi) were tested in vivo. • Two antagonistic bacteria (Bacillus spp < /em>.) with great inhibitory effect towards R. solani and F. solani were secured from lentil rhizosphere and adequately used as a biocontrol agents against the two pathogens in pots experments. | ||||
