Abstract

. Isolation process revealed 6 isolates belong to Fusarium oxysporum
and three Rhizoctonia solani isolates. Pea plants cv. Lincoln grown in
infested soil shows the typical root rot symptoms. Isolate PF6 was the
highest virulence among the tested Fusarium isolates. And RPl shows
the highest severity among Rhizoctonia isolates.
. The dominant pathogen in diseased pea-plants is Fusarium sp is (its frequency is 54.5 %) followed by Rhizoctonia sp (15.9 %).
. From all tested cultjvars and lines, only L4 is highly resistant and L2
is resistant and L8 considered moderate resistant to fusarial infection.
Only line L 7 is moderately resistant to R. solani.
. Czapek’s media was the best one for the growth of F. oxysporum and R.. solani. While Waxman’s medium was the best for Fusarium
sporulation.
. The highest growth of both fungi was obtained at pH 7.0.
. The maximum growth of F. oxysporum was obtained at temperature of
30 followed by 25°C and the maximum growth for R. solani was
recorded at 25 followed by 30°C.
