This work was carried out at the Girls College of Education, Jeddah, Saudi Arabia. Apparently healthy looking seeds of soybean (Gylcin max) pre-soaked in 25, 50, 75 and 100% concentration of 4, 8 and 12-day- old cell-free culture filtrates of seed-borne Aspergillus niger, Fusarium culmorium, Penicillium sp. and Rhizoctonia solani of soybean seeds for 2, 4, 6, 8 and 24 h were investigated for phytotoxicity. Results showed that all the fungal filtrates irrespective of filtrate concentrations, filtrate age and presoaking period significantly (P # 0.05 and P # 0.01) reduced percentages seed germination and seedling development when compared with the control. Percentage seed germination and seedling growth decreased with increase in filtrate concentration, filtrate age and presoaking time in all the fungal filtrates. Sterilized filtrate of A. niger, F. culmorium, Penicillium sp and Rhizoctania solani lost some of their phytotoxicity than non-sterilized filtrates.
