Abstract
This study was carried out to determine the effect of Phragmites communis & Schanginia aegyptioce leaves used as source of carbon and potato extract & nutrition solution ( unigreen) used as source of nitrogen & other nutrients elements on the growth and probagetion of the biological fungus Trichoderma harzianum . The Laboratory experiments showed that although all the culture media were effective , Schanginia aegyptioce powder + nutrition solution ( unigreen) was the most effective concerning the sporulation (1.9 x 610spore/ gm ). Also It achieved better economical value since it verified highly effective on Rhizoctonia solani attained 100% since it increased significantly the percentage of seed emergence to 90 % & significantly decrease the percentage of seedling damping- off which reached 10 % compared with control treatment (contaminated) the percentage of seed emergence reached 66.6 % & the percentage of seedling damping- off reached 33 % . On the other rand, it did not differ significantly from the treatments of the chemical fungicide (vitavax) and control (uncontaminated) treatment.
