| Abstract : This study was carried out to evaluate the efficiency of the associated fungus to the seeds and stems of Dodder plant on controlling Dodder plant parasitic on egg plant , in which eighteen species elated to seven fungus genesis was isolated from dodder plant from eight locations from Babylon Gorneate . A. Oryzae and A. niger was isolated from tested samples , in which the highest frequent fungus was A. niger with 28.43% rate followed by A. oryzae with 32.50% rate followed by A. terreus with 19.16% rate while peneicillium fuscum was found with the rate of 1.1% . The pathogenicity test for H. oryzae induce high effect in reducing germination rate of egg plant seeds to 3.5 comparing with alt . sp 5 in which the germination rate off egg plant seeds was 20.25 , also A.niger redus seed germination of dodder which was 0.5 comparing with the control which was 20.00 , A. niger redus seed germination of dodder which was 0.5 comparing with the control which was 20.00 . Also results of this study indicate significant differences in dodder seed germination which range between 2.75 – 18.00 for A. niger , Alternaria sp1 comparing with the control which was 23000 , while the germination of egg plant seeds with fungus filtrate for A. terreus and Chaetomium elatum . Was 20.25 , 22.25 respectively comparing with the control which has germination rate of 23.25 . Results of spraying the filtrate of selected fungi ( 100% conc. ) on the old growth of dodder contain seeds . shows significant decrease in germination comparing with the control which was 2.50 for A. terr and A. sp while the seed germination in the control was 11.00 . | ||
