Abstract
1- The isolated fungi from soybean and peas damped off and root- rotted were Rhizocotania solani , Sclerotium ralfsii and Fusarium spp
2- , Sclerotium ralfsii was the most aggressive fungus and caused severe damping off( 59.2 and 20.4 % pre- and post -emergence damping – off , respectively ) followed by R. solani ( 34.6 and 13.6%) pre- and post -emergence damping – off , respectively . Fusrium spp also caused damping – off but to a lesser extent comparing to S. rofsii or R. solani
3- growth of all the tasted host more than occurred when the hyperparasites and the host were inoculated in the same time.
4- Culture filtrate of T. hazianum with all tested concentrations ( 20- 100%) reduced the fungal growth of all tested fungi . . The increase in the culture failtrate concentration , the decrease in fungal dry weight for all tested fungi
